Title: Detector for flow rate of sucked air of internal combustion engine for car
Inventor: HIRANO JIYUUMEI
IPC: F02D35/00
Filed: 1979-12-29
Abstract: PURPOSE: To make it possible to detect even a low flow rate easily by holding flows of ultrasonic-wave transmitter and receiver sides at high and low temperature respectively and by differentially detecting Karman vortexes that correspond to the volocities of the flows.  
     CONSTITUTION: When shutter valve 4 is closed through detector 5 for low flow-rate air suction operation range mode and servomechanism 6, a high-temperature exhaust air flow passed through air conduit 2 and a fine sucked air flow from air conduit 7 are rectified via filter 10 to generate clockwise and counterclockwise Karman vortexes 13 and 14 of high and normal temperatures at sides of ultrasonic- wave transmitter 16 and receiver 18 for Karman vortex detection through vortex generation pole 12. Therefore, an ultrasonic wave modulated corresponding to vortexes 13 and 14 is received by receiver 18 to detect securely and differentially fine vortex 13 proportional to the flow rate that corresponds to the amount of sucked air. As a result, even if the flow rate is low, the amount of sucked air can be detected easily and securely.

Inventor: TOKIDA HARUHIRO
IPC: G01D5/244
Filed: 1993-06-18
Abstract: PURPOSE:To reduce current consumption of a speed detector. CONSTITUTION:The speed detector comprises a sensor 1 principally producing a pulse corresponding to the position or the speed of an object 10 to be measured, a circuit 5 for generating reference clock signal Ck, and a counter 7 for measuring the time interval of a pulse from the sensor 1 based on the reference clock signal Ck. The speed detector further comprises a clock gate 6, disposed between the reference clock generating circuit 5 and the counter 7, for obtaining a speed signal based on a count received from the counter 7 and opened by a detection signal Sp received from the sensor 1 through an oscillation removing circuit 4, for example, whereas closed by a gate close signal received from the counter 7. When the count of the counter 7 is not required, the clock gate 6 is closed by the gate close signal to interrupt provision of the reference clock signal Ck to the counter 7 thus suppressing current consumption of the counter 7.

Title: Aggregate of valve
Inventor: AANORUDO II TEIRAA
IPC: B29C45/26
Filed: 1981-10-30
Abstract: A hot sprue valve assembly is provided for controlling flow of molten material into the mold cavity of an injection molding machine. The valve assembly is particularly designed for use with an injection molding machine for molding centrally apertured record discs, such as video information discs. The valve assembly includes a hot sprue bushing defining a heated flow path for passage of molten material toward a stationary dispersion head positioned centrally within the mold cavity. The dispersion head directs the molten material to flow in a generally radially outward direction with substantially uniform radial distribution into the mold cavity. A cylindrical sleeve valve is carried about the hot sprue bushing for reciprocal movement between an open position retracted from the mold cavity to permit flow of the molten material into the mold cavity, and a closed position projecting into the mold cavity in seated engagement with the dispersion head simultaneously to prevent flow of the molten material into the mold cavity and to mold a central aperture in the disc.

Title: Method for estimating gas pipe capacity
Inventor: TANAKA TAKASHI
IPC: G01F3/22
Filed: 1993-07-13
Abstract: PURPOSE:To simply estimate the pipe capacity in a specific zone in a short time by arranging a supply gas pressure fluctuating device most upstream the estimation object zone, actively changing the gas pressure at a fixed time interval, and measuring the fluctuation patterns of pressure and flow. CONSTITUTION:A pipe capacity estimating device 6 drives a supply gas pressure fluctuating device 3 to fluctuate the supply gas pressure at a fixed time interval. A pressure measuring device 4 and a flow measuring device 5 measure the fluctuations of pressure and flow in an estimation object zone 1 and output them to the estimating device 6. The estimating device 6 estimates the total capacity in the estimation object zone 1 based on the fluctuations of pressure and flow measured by the device 4 and the device 5. The fluctuations are small when the object zone 1 is short, and the fluctuations are made larger as the object zone 1 becomes longer.

Title: Caterpillar vehicle
Inventor: SUZUKI HIDEAKI
IPC: B62M27/02
Filed: 1989-07-05
Abstract: PURPOSE:To improve the running performance and to improve the driving ability on a very uneven bad road by providing a oscillation regulating means for keeping an angle of oscillation of a rear arm to a rear fork within a designated range. CONSTITUTION:In the case where the trailing end side of a caterpillar device 10 is out of contact with the ground, such as the case of passing a projection, a rear sub-cushion 21 is about to stroke to a full-elongation position, so that a rear arm 12 is about to oscillate downward at the same time. When the rear arm 12 oscillates to a designated angle, however, the oscillation is regulated by an oscillation requlating means 25 and stopped. Accordingly, the rear arm 12 is kept from being oscillated downward over a designated angle. Thus, it is possible to prevent the generation of a stack caused when a guide roller 16 provided on the trailing end of caterpillar device 10 gets under the snow and furthermore at the time of passing a projection, the trailing end side of the caterpillar device 10 is not positioned on an inclined surface, but quickly separated therefrom so as to facilitate passing a projection.

Abstract: PURPOSE:To improve dielectric strength and degree of coupling between winding with each other by a method wherein a winding wound to one side bobbin is consisted of windings at least two sorts and a sort of winding thereof is divided to two and more and the other sort of winding is inserted between the divided winding and then they are wound together. CONSTITUTION:A winding P1 is divided in two of P11 and P12 and is designated as current division type in which these windings are connected to the common terminals 16 and 17 in parallel. Additionally, winding constitution is made by means that another winding P2 is sandwiched between the divided windings P11 and P12. As double bobbin constitution is provided by consisting of a coil bobbin 22 wound by the winding 1 and a coil bobbin 23 wound by a winding S, therefore dielectric strength comes to be high. The divided windings P11 and P12 are entwisted respectively with plural wire materials or are subjected to neatly- ordered winding and thereby degree of coupling between the windings P1, P2 and the winding S is improved and leakage inductance becomes further smaller.

IPC: H01L21/027
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To considerably improve dimensional accuracy of a resist pattern even when a phase shift mask is used together with a photomask. SOLUTION: A thickness of a quartz plate 14 is changed so that a spherical aberration amount is, represented by Seidel aberration coefficient, set at -0.025λ to -0.045λ. Thereby variation in dimensions of both of a 0.20μm pattern formed with a phase shift mask and a 0.25μm pattern formed with a photomask can be made small at the same time. Therefore, even when the phase shift mask is used together with the photomask with a single excimer laser stepper 1, dimensional accuracy of both of them can be considerably improved.
