Title: Engine tuning structure
Inventor: TAMURA YASUKI
IPC: F02D45/00
Filed: 1991-06-20
Abstract: PURPOSE:To improve the acceleration performance of an automatic transmission car by specifying the volume of the air-intake system so that a resonance condition may be generated in the stall condition during acceleration. CONSTITUTION:A resonator 6 connected to an air-intake pipe 3 constituting an air-intake system is capable of changing the volume by moving a partitioning plate 7. Here, in an engine 1 of an automatic transmission car, the volume of the air-intake system is specified so that the resonance condition may be generated in the stall condition during acceleration. This specification allows the resonance supercharging to be realized in the stall condition during acceleration, and the stagnation of the engine speed is eliminated due to the torque rise, leading to improvement of the acceleration performance.

Title: Processing window assignment system
Inventor: KUJIRATSU ATSUSHI
IPC: G06F12/00
Filed: 1991-06-20
Abstract: PURPOSE:To prevent the futile use and the shortage of the computer resources by securing a constitution where a system decides automatically the number of required processing windows based on the traffic value and the working ratio of the system. CONSTITUTION:A counter is provided for each terminal in the transaction processing applied from a terminal in an on-line system. The counter counts the number of applied transactions at each fixed time interval during the working of the on-line system. The counting result of transactions is recorded to the counter and the file stored in a auxiliary storage. When the on-line system is started again, the counter value is restored out of the file of the auxiliary storage. Then the latest traffic value and working ratio of the on-line system are obtained from the restored counter value. Thus the least necessary number of processing windows can be automatically decided.

Title: Image pickup device
Inventor: TATSUMI SHINGO
IPC: H04N19/625
Filed: 1991-06-20
Abstract: PURPOSE:To interpolate the defect of the picture element of a solid state image pickup element without increasing a circuit scale. CONSTITUTION:In a period in which the output of the solid state image pickup element 2 is normal (period free from defect), the switch 7-8 of a predictive encoder 7 is connected to the side of (a), and normal predictive encoding (data compression) is executed. When it becomes the timing of the defect of the picture element, the switch 7-8 is connected to the side of (b), and '0' of digital data is supplied to the loop of the predictive encoder 7. Namely, at the timing of the defect, the difference of a signal Xn at present and the signal Xn-1 of the one line preceding same timing is made '0', and interpolation by a preceding value is executed. Thus, by only providing the predictive encoder 7 with the switch 7-8, the defect can be interpolated.

Title: Oscillation proof apparatus for air spring
Inventor: KARASAWA KOUICHI
IPC: F16F15/027
Filed: 1980-10-23
Abstract: PURPOSE:To prevent transmission of oscillation from a floor and improve absorption of low frequency oscillation by controlling internal pressure of an air spring using a non-contacting level sensor at a level detection point. CONSTITUTION:A non-contacting level sensor 21 which is to detect mechanical level fluctuation in a non-contacting method is set in a properly spaced position with respect to a lower face of a machine loading disk 16. A control circuit 22 transmits a signal output from the non-contacting level sensor 21 to a suction valve 17 for an air spring 15 or an exhaust valve 18. An ordinary oscillation frequency of a floor itself is 10Hz which any universally known air spring can absorb, however, movement of machine gravity sometimes causes a vibration of several Hertz order that cannot be absorbed. This apparatus effectively acts upon such low frequency oscillation and absorbs it.

Abstract: PURPOSE:To reduce the beam path obstacle of laser beam, by providing such a structure that a contact pin for the electrical continuity with the electrode part of a resistor is erected on a transparent insulating base plate pervious to laser beam and wiring is performed to a transparent film conductor pervious to laser beam. CONSTITUTION:In trimming a film resistance base plate 13 having a resistor 11 and an electrode part 12 formed thereto, a transparent insulating base plate 14 easily transmitting laser beam is used and holes are provided to the base plate 14 at the positions corresponding to the electrode part 12 while contact pins 15 having springiness are planted to the holes in an upright state. In the next step, the pins and external connection terminals 16 are connected by transparent thin film conductors transmissive to laser beam, for example, a thin film pattern 17 formed of indium oxide to which about 5wt% of tin is added. By using thus constituted resistance value measuring probe, the resistor 11 can be trimmed and the beam path obstacle of laser beam can be reduced because laser beam 18 is transmitted even if the conductor 17 is present on the beam path of said beam 18.

Title: Optical device
Inventor: SAITO TOMIHISA
IPC: G02B6/28
Filed: 1989-06-12
Abstract: PURPOSE:To improve an isolation characteristic by obtaining such structure that a part of the end surface of a rod lens is obliquely cut off, the surface of the rod lens is roughed or a swollen part having the same refractive index is attached. CONSTITUTION:The second rod lens 12 has the structure that a part of the end surface of the rod lens is obliquely cut off so as to include a symmetric position by interposing an optical axis with respect to a second optical fiber 5. A part of light proceeding to a ground surface 14 is reflected on a B part. However, the direction of the reflected light is out of an original optical path by the oblique ground surface 14. Then, when the angle of the oblique ground surface 14 is set so that the light arrives at the side surface of the rod lens before arriving at a beam splitter film 3 in the second rod lens 12, the light reflected on the B part gets out at the side surface of the rod lens or it is reflected to the inside of the rod lens again and the light is not returned to the optical fibers 4 and 5. As the result, the isolation characteristic is drastically improved.

Filed: 1988-06-17
Abstract: PURPOSE:To know the multiplicity of a multi-job without a special display device by displaying the multiplicity of the jobs in the middle of parallel execution by means of the display state of a cursor. CONSTITUTION:When there is an input request from a second job among plural jobs in the middle of parallel execution and when the input request from first and second jobs are overwrapped, namely, when multiplicity shows '2', the multiplicity information is stored in a cursor control register 4. A display controller 5 emits a display signal in accordance with information that the multiplicity shows '2'. The display state of the cursor on the display screen of the first job which as made the input request first is changed by the display signal from the display controller 5. Thus, the multiplicity of the multi-job can be displayed without providing the special display device.

Abstract: PURPOSE:To accurately form ultrafine vertical wirings and resistors by using a property that the bonding surface of an SiO2 film formed by a CVD method is quickly etched by wet etching, thereby facilitating the hole of the bottom of an ultrafine groove. CONSTITUTION:After a convergent groove 10 is formed on an Si substrate 1, an SiO2 film 12 is accumulated by a CVD method. Then, it is wet etched with etchant such as fluoric acid. Generally, since the accumulated film of SiO2 has a property that the bonding surface 13 of the film 12 grown from the side wall of the groove is quickly etched, the surface 13 is preferentially etched as a result of the wet etching to form an open groove 14. Thereafter, a polycrystalline silicon is filled in the groove to obtain a vertical wiring structure. Polysilicon high resistance is filled in the groove 14 to form an accurate resistance element.
