IPC: H03H9/10
Filed: 1979-05-30
Abstract: PURPOSE:To increase the stability and to make accurate the oscillation, by sealing the crystal body and gas adsorbent in a package via an intermittent part. CONSTITUTION:In a package formed with a cover 2 welded in airtightness at the external flange of a base 1, a crystal body 4 and gas adsorbent 6 are connected and supported with electrodes 7, 7' and 8, 8'. Between the crystal body 4 and the adsorvent 6, a shutter plate 9 is mounted on the base 1 in airtightness with a leg 10. The adsorent 6 adsobvs the gas produced in the package and at airtight sealing of a vent tube 3 to always keep clean the inside of the package. A lot of gas and particles are discharged from the adsorbent 6 in this case. The shutter plate 9 prevents the gas and particles from being stuck to the crystal body 4 for the change in the resonant frequency of crystal oscillator.

Title: Method for transferring medium to be recorded in recording apparatus, and recording apparatus
Inventor: KANAMARU HIROSHI
IPC: B41J13/00
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To improve transfer efficiency for a medium to be recorded and a record speed of a recording apparatus. SOLUTION: A specific length detection sensor 28 detects whether or not a medium 14 to be recorded which is placed at a paper feed part 1a of a recording apparatus is longer than a specific distance L1. When the medium 14 to be recorded is longer than the specific distance L1, a part of the medium 14 corresponding to the specific distance L1 is set as a 'front half part' and a part exceeding the specific length is set as a 'rear half part'. When images are recorded by a recording head 2 to the front half part of the medium 14, whether or not a rear end part of the medium 14 passes a medium pass sensor 27 is not detected and the medium 14 is transferred by an LF roller 11 or the like. When images are recorded to the rear half part of the medium 14, the medium 14 is transferred while it is detected whether or not the rear end part of the medium passes the medium pass sensor 27.

IPC: G08B23/00
Filed: 1978-06-06
Abstract: PURPOSE: To detect abnormality accurately by attaching an alarm detection circuit which generates an alarm signal when a PLL circuit is not locked or when reception of a signal is interupted.  
     CONSTITUTION: In the timing extraction system using a PLL circuit, signal (f) differentiated by the input of phase comparator PC24 is expanded in pulse expander circuit 31 by one bit of the repetitive frequency of voltage control oscillator 28 and signal in case of coincidence with another input (g) of PC24 is extracted by FF circuit 32 and then pulse-expanded by pulse expander circuit 33 to obtain an alarm signal, thereby detecting an unlocked state. At every time when the change point of received signal (a) is detected, pulses are expanded by pulse expandar circuit 35 and when the output is OFF, an alarm signal is sent out, thereby detecting the state when the received signal is intermitted. Two alarm detection circuits added make it possible to detect abnormality accurately.

Title: Valve system for internal combustion engine
Inventor: NAKAMURA MAKOTO
IPC: F01L13/00
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To always obtain stable and smooth opening/closing operation of an engine valve by preventing deformation of valve timing characteristics immediately after lifting down from the maximum lift position. SOLUTION: An oscillation cam 17 oscillatably supported to a driving shaft 13 is operated for opening an intake valve 12 by means of a valve lifter 16 by the use of cam lifting force transmitted from a driving cam 15 through a transmitting mechanism 18, against the force of a valve spring. Oscillation direction from the maximum lifted position to the lift down side is samely set, in respect to the intake valve according to the rotational direction of the driving shaft 13 and a cam surface 22 of the oscillation cam 17. Frictional force between the driving shaft and the oscillation cam immediately after the maximum lifting is thus applied to the lift-down direction. The oscillation cam is speedily inversed, for preventing deformation of the valve lifting characteristics.

IPC: H01L21/304
Filed: 1984-04-06
Abstract: PURPOSE:To control disposition of a monomolecular film or a mono-molecular multilayered film in two dimensions by forming a pattern of a monomolecular film or a monomolecular multilayered film after scanning the surface of the base with gamma rays under the environmental gas absence. CONSTITUTION:A base is prepared by forming a monomolecular multilayered film 1-2 of arachidin acid on the surface of the Si (100) substrate 1-1. When the base is put into the vacuum environment and scanning is performed on the surface of the base with gamma rays using a mask, a pattern is formed by the transmutation of the hydrophobic portion of acid in the scanning area 1-4. After developing a solution made by dissolving a mixture, which is a mixture of arachidin acid and a derivative of merocyaninl shown in the formula I with a ratio of 1:1 in mol, in chloroform at 1X10<-3>mol/l, on the surface of water, 10 laminated layers are formed with a pulling up speed of 8cm/min and the surface pressure at 30dyne/min. The monomolecular multilayered film 1-5 is formed in accordance with the pattern, on the area of 1-3 only but not formed on the area of 1-4. Thus, by the modification of the base using gamma rays, the formation of a monomolecular film or a monomolecular multilayered film on the base in accordance with a pattern is made possible.

Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To enable sure backup with a slave side controller by providing the slave side controller with a function for skipping a task so as not to go down with the same task as the side of master. SOLUTION: When any abnormality occurs in a task A of the software of a controller 1 in a step 11 and the controller 1 goes down in a step 12, the task A, which is the factor of down of the controller 1, is detected through a transmission line by a controller 2 in a step 13. In the next step 14, control is switched from the controller 1 to the controller 2 but the controller 2 is prevented from going down by skipping the task A as shown in a step 15 and can be continued by control like a step 16. Thus, since the controller 2 detects and skips the task A of the software, which is the factor of down of the controller 1, backup in the case of abnormality is performed.

Abstract: PURPOSE: To eliminate a freezing tendency that freezing repeatedly happens in a heat-exchanger by a method wherein when specified times of freezings of one part of water to be cooled in the heat-exchanger are detected within a specified period of time, a refrigerator is stopped for a specified period of time. CONSTITUTION: When one part of water to be cooled is frozen in a heatexchanger 2 during an operation of an ice-making device, a pressure switch 8 detects the freezing, and the information is notified to a controller 14 by a circuit 13. The controller 14 stops the operations of a refrigerator 1 and water supply pump 10 by a signal from the pressure switch 8, and at the same time, totally opens a solenoid valve 12, and feeds replenishing water of a normal temperature into the heat-exchanger 2, and releases the freezing in a short period of time.

Title: Television receiver
Inventor: EBE NAOTAKA
IPC: H04N9/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To automatically prevent the deviation of screen by controlling a switch such that a synchronizing signal or a composite video signal is not supplied to a digital comb-line filter in an external display mode but the signal is detoured directly to a synchronizing separator circuit. SOLUTION: An input terminal 100 includes a terminal 12 to receive a composite video signal of a television signal, a terminal 1 to receive a composite video signal or a synchronizing signal from an external device, input terminals 2a-2c to receive an RGB signal from the external device and an input terminal 3 to receive a high speed switch signal. An input detection circuit ANDs the high speed switch signal and a synchronizing signal from a synchronizing separator circuit and applies peak holding to the ANDed signal to obtain a control signal, which is used for switching control of a switch circuit 5. In the case of the external display mode, the switches SW1, SW2 are switched to connect each of terminals 2, 3. Thus, the composite video signal bypasses a digital comb-line filter and is fed to the synchronizing separator circuit and a video chroma processing circuit.
