Title: Surface mounting land
Inventor: ABE YOSHINOBU
IPC: H05K3/34
Filed: 1993-03-12
Abstract: PURPOSE:To provide the shape of a surface mounting land, which can prevent a lead from floating due to coplanarity of a lead without increasing the printed application thickness of a solder paste. CONSTITUTION:A number of land bodies 21 are slenderly formed in the surface of a board at a pitch corresponding to the IC lead of a quad flat package(QFP). A round wide surface part 22 so as to be wider than the width of the land bodies 21 is formed into one body in a part of the respective land bodies 21. Each wide surface part 22 is provided by alternately displacing the adjacent ones so that they do not stand in a line with each other to prevent the occurrence of a bridge between the adjacent wide surface parts 22. When a solder paste is applied by printing on the respective land bodies 21 for reflow, the height of a melted solder alloy partially becomes higher on the wide surface part 22 than on the land bodies 21. The melted solder alloy on the wide surface part 22 surely comes into contact with a lead in the upper side of lead coplanarity which makes the cause of floating a lead.

Title: Optical disk device
Inventor: ICHIKAWA KOJI
IPC: G11B7/005
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To make possible answering to plural optical disks with different initial positions by providing an optical disk device with a stopper stopping disk inner peripheral side movement, a sensor detecting radial direction movement and the required number of stop position detection parts. SOLUTION: When a rotational speed of a spindle motor 2 arrives at a prescribed value, a movable head performs initial operation. A controller presses the movable head at an inner peripheral side stopper 63 formed on a base 6, and recognizes that a head is stabilized in an innermost periphery by that an output of a photosensor 64 continues for a prescribed time to focus an objective lens 51 by a two-dimensional acutuator 5. The stopper 63 is set in so that the lens 51 is positioned on a control data recording area 11 on the optical disk 1, and when the lens 51 is focused, the controller reads in a condition recording or reading out the disk 1 to move to next operation.  When the focusing doesn't succeed, the controller moves the movable head to an outer peripheral side, and moves it to the initial operational position of the outer peripheral side by using the output of the sensor 64 to position the movable head.

Title: Cam tappet with heavy metal alloy
Inventor: HAMADA HIROSHI
IPC: F01L1/14
Filed: 1980-04-23
Abstract: PURPOSE: To prevent a scarfing by a method wherein a specified volume of heavy metal is added to a base material of a cam or a tappet for use in opening or closing valves of an internal combustion engine and the like.  
     CONSTITUTION: 0.1 to 7% (weight) of one or more elements selected from elements of heavy metal such as lead, zinc, bismuth, tin and tellurium is added to the cam or tappet of which base material is any one of steel, cast steel and cast iron. For example, when a lead is added, the lead is hard to be combined with the base iron and is left in the base iron as its molecular form. Since a lead shows a low degree of hardness, no cutting or grinding of the mating components element, as well as a lubricating characteristic of the lead itself shows a high value to accommodate a local breakage of the oil film produced in the base iron. As a result, a sliding friction resistance shows a low value and a heat generated under a sliding movement is  made to be reduced. In this way, it is possible to prevent the scarfing.

Title: Magnetic head
Inventor: SAITO MITSUYOSHI
IPC: G11B5/187
Filed: 1986-03-11
Abstract: PURPOSE:To obviate the generation of adsorption by coating Al2O3, TiC and SiC to the sliding surface of a magnetic head with a magnetic recording medium. CONSTITUTION:The magnetic head 2 is pressed to the bottom surface of the magnetic recording medium 1. The head 2 is coated with the Al2O3, TiC or SiC on the sliding surface of the base material thereof. The Al2O3, TiC and SiC have poor wettability with water. Since these materials are coated on the head 2, the adsorptive power is suppressed. Since the wettability of the sliding surface of the head 2 with water is thereby debased, the adsorption between the head 2 and the medium 1 is effectively prevented.

IPC: G01S13/76
Filed: 1988-03-07
Abstract: PURPOSE:To achieve a highly accurate measurement of distance, by measuring signal transmission time in a transmitting system and an intermediate frequency receiving system as each query pulse is sent out to detect a variation of the signal transmission time in the transmitting system and the intermediate frequency receiving system for temperature changes. CONSTITUTION:To correct a system delay time, a timing pulse generation circuit 21 outputs a distance start pulse at a timing delayed in time from a query pulse 2a to be supplied to gates 11-1 and 11-3 within a distance measuring circuit section 11 through a line 35. This gate 11-1 opens a gate in response to a distance start pulse to supply a clock signal outputted from a clock generator 22 to a distance measuring counter 11-2 of the distance measuring circuit section 11. The timing pulse generator circuit 21 also outputs a transfer pulse immediately before the outputting of the distance start pulse. The pulse is fed to the distance measuring counter 11-2, which has a distance measurement start reference value preset by the transfer pulse to start a distance measurement from the value thereby enabling a stable measurement of distance.

Title: Bias applying method for developing and cleaning process
Inventor: TAKAHASHI MICHIO
IPC: G03G21/00
Filed: 1978-05-04
Abstract: PURPOSE:To achieve the reduction in the bias effect at the developing by the toner deposited on sleeve surface by changing over bias potential to be applied to a sleeve  in developing and cleaning and making the potential difference between the photoreceptor and sleeve as small as possible. CONSTITUTION:A photoreceptor is charged to, e.g., -600V in developing step and is next exposed so as to become dark part -500 and bright part -100V. Next, a bias -250V is applied thereto to let toner 2 be deposited on the photoreceptor. After transfer, the bias is made -50V, photoreceptor +200V, potential difference 250V to avoid depositing the toner 2 on the sleeve 1. Namely, the bias of the cleaning step is so set that the potential difference between the photoreceptor and sleeve  is made smaller than the bias to be applied in the developing step. This obviates  deposition of the toner on the developing sleeve in the cleaning step and obviates  the reduction in the bias effect in the developing step, hence enables the ground stains of the copy to be prevented.

Title: Air flow rate measuring instrument
Inventor: KOBAYASHI CHIHIRO
IPC: G01F1/68
Filed: 1993-03-15
Abstract: PURPOSE:To stabilize the measurement accuracy of an air flow rate measuring instrument even when a reverse flow occurs due to large variation of the flowing speed of air by arranging a plurality of pieces of temperature sensitive resistors for detecting the temperature of intake air. CONSTITUTION:An exothermic resistor 4 has such a structure that cannot distinguish the flowing speed of air in the normal direction with that in the reverse direction and causes the jumping of its output voltage by outputting the flowing speed in the reverse direction in the same way as that for the flowing speed in the normal direction. Therefore, a temperature sensitive resistor A 5 is arranged at a position where the resistor A 5 is easily affected by the heat of the resistor 4 when air flows in the reverse direction and another temperature sensible resistor B 6 at another position where the resistor B 6 is hardly affected by the heat of the resistor 4 when the air flows in the normal or reverse direction. The resistor B 6 indicates a fixed intake-air temperature when such a state occurs that a reverse flow is generated at a fixed intake-air temperature, but the resistor A 5 is affected by the heat of the resistor 4 and its detecting temperature abruptly changes only when a reverse flow occurs. On the other hand, the detecting temperature of the resistor A 5 similarly changes when the intake-air temperature changes, but the temperature change is not so abrupt as compared with that at the time of reverse flow. Therefore, the presence/absence and flow rate of a reverse flow in an intake pipe can be discriminated from the variation of the detecting temperature of the resistor A 5.

Abstract: PURPOSE:To quickly suppress residual vibration after ink injection and to enhance pulverizing frequency, by providing a plurality of projections to at least a part of the inner wall of a pressure chamber so as to make flow resistance towad a nozzle smaller than the flow resistance to the opposite direction. CONSTITUTION:A plurality of projections are formed to at least parts of the inner walls of the pressure chambers 16-1-16-n of a recording head and ink directed to the outlets 26 of the pressure chambers communicated with guide paths 20-1-20-n from the inlets 24 of the pressure chambers communicated with supply passages 18-1-18-n. In this example, the width (the distance between side walls) of each pressure chamber is constant and a large number of saw tooth shaped projections 28 to said walls. Each saw tooth shaped projection is formed so as to make the flow resistance toward an a-direction smaller than the flow resistance to the opposite direction of (a) and, therefore, acts as large resistance against the vibration from a nozzle side to make it possible to quickly attenuate residual vibration. On the other hand, said projection does not act as large resistance against the supply of the ink and the ink can be smoothly supplied.

Abstract: PURPOSE:To enable operating a device referred to above even in the case where the heating capacity of the heating means for heating the solution in a generator is liable to change or the heating capacity is low at all times and make it unnecessary to take measures for preventing crystallization of lithium bromide even where an aqueous solution of lithium bromide is in use for the solution. CONSTITUTION:In a high-temperature generator 30, there are provided a pool of solution into which a dilute solution channel 26 conveys a dilute solution and a heat-transfer tube by which the dilute solution in the pool of solution is heated. High-temperature vapor, which has absorbed heat discharged from a fuel cell (not shown in diagram), is sent into the heat-transfer tube to heat the dilute solution to boil and make it generate refrigerant vapor. The boiling solution overflows a weir marking a specified liquid level and, as a solution of intermediate strength, falls into a channel for a solution of intermediate strength placed under the pool of solution; from this channel the solution flows into a high-temperature heat exchanger 8 through a conveyance line 7 for solution of intermediate strength. Thus the generation of refrigerant vapor and the separation of the refrigerant vapor from the solution of intermediate strength can be effected without using a conventional liquid-lifting tube and a separator.

Abstract: PURPOSE:To prevent the wetting of a floor by eliminating the flocculation and growing of liquid droplets by preventing the collision of sprayed liquid droplets with a curved wall by providing an opening injecting air between the curved wall and the jet stream layer of the sprayed liquid droplets. CONSTITUTION:A back surface opening 20 and a side surface opening 22 are formed to an air duct 10 on this side of the curved wall 10A of said duct 10 and the air sent from an air feed fan 16 is blown out between the jet stream layer A of the sprayed liquid droplets from a spray nozzle 24 and the curved wall 10A from the back surface opening 20. Therefore, the sprayed liquid droplets from the spray nozzle 24 are prevented from directly colliding with the curved wall 10A and the side wall of the duct and directionally turned without generating the flocculation and growing of the liquid droplets. The sonic wave generated from the nozzle 24 collides with the curved wall 11A to be arrested. Therefore, the wetting of a floor due to the flocculation and growing of the liquid droplets injected into an air conditioning chamber is eliminated.
