Title: Automatic transmission device
Inventor: SATO YUJI
IPC: F16H63/20
Filed: 1987-05-30
Abstract: PURPOSE:To improve accuracy by driving second and third solenoid valves by means of pulses having a high frequency which forms one period in a shorter time than the time at which the second and third solenoid valves respond by their turning on and off. CONSTITUTION:Both fluid pressure differential cylinder 1a for a selecting operation and fluid pressure differential cylinder 1b for a shifting operation have the same structure and the small pressure-receiving area side chamber 13 of the cylinder 1a (1b) is connected to a hydraulic source via a first solenoid valve 5 while connecting its large pressure-receiving area side chamber 15 to a tank side via a third solenoid valve 7. Also, both of the side chambers 13, 14 are connected to each other via a second solenoid valve 6. And, the second and third solenoid valves 6, 7 are driven by pulses having a high frequency which forms one period at a shorter time than the time at which the second and third solenoid valves 6, 7 respond by their turning on and off. Thereby, an analog type opening area control can be performed, enabling the minute control of the flow-in/flow-out quantity of fluid pressure and, since a highly accurate mechanical position output can be obtained from the fluid pressure differential cylinder 1a (1b), sifting and selecting operations can be favorably performed.

Filed: 1992-05-29
Abstract: PURPOSE:To reduce troublesome telephone calls for a mobile telephone subscriber and to effectively utilize radio resources by providing a subscriber information registration device and an incoming call control means in a mobile communication switchboard. CONSTITUTION:When an incoming call is present from a subscriber B through a public telephone network (NW) 3 to a subscriber A of a mobile set (MS) 1, at the mobile communication switchboard (MSC) 2a, a CPU22a recognizes the corresponding caller information registration device (HLR) 23a from the caller number of the subscriber A received through a speech path switch (SW) 21 and performs access. The MSC2a stores a password instrinsic to the subscriber A of the MS1 in a password memory part (PWM) 24 inside the HLR23a. Then, the CPU22a collates the password of an incoming call caller transmitted by a call originating subscriber B at the time of originating the call and the password of the subscriber A registered in the PWM24, allows the incoming call in the case of coincidence and refuses the incoming call in the case of non-coincidence.

Title: Magnetic pulse compression circuit
Inventor: OTEGI HIROICHI
IPC: G05F7/00
Filed: 1988-06-06
Abstract: PURPOSE:To perform pulse compression in high repetition for a long time by making the changing quantity of the magnetic flux density of the core of the saturable reactor in the final stage in the course of pulse compression smaller than that of the magnetic flux density of the core of the saturable reactor in the stage just before performing the pulse compression. CONSTITUTION:The inductance of the loop from a capacitor 7 to the capacitor 7 through a capacitor 8 and saturable reactor 10 is made smaller than that of the loop from a capacitor 6 to the capacitor 6 through the capacitor 7 and a saturable reactor 9 after the switching of the saturable reactor 9. Therefore, the supplying time gamma3 of a pulse current i4 becomes shorter than that gamma2 of another pulse current i3. In addition, the inductance of the loop from the capacitor 8 to the capacitor 8 through a capacitor 14 and saturable reactor 15 is made smaller than that of the loop from the capacitor 7 to the capacitor 7 through the capacitor 8 and saturable reactor 10. Therefore, the supplying time gamma4 of a pulse current i5 becomes shorter than that gamma3 of another pulse current i4. Thus pulse compression can be performed in high repetition for a long time.

Title: Catalyst combustion device
Inventor: NOMURA YOSHIHIRO
IPC: F23D11/40
Filed: 1988-06-06
Abstract: PURPOSE:To enhance oxidizing cability on a catalyst body, to improve combustion properties and enlarge a combustion area by a method wherein a premixing chamber is heated with the heat of burnt gas in an exhaust passage to promote the gasification of fuel, and air for combustion is preheated. CONSTITUTION:When an air change-over valve 40 is changed over after combustion for a predetermined period of time, air is fed through a bypass 33 to cause no spinning stream of air within a premixing chamber 26, and flames spread out to shift the initial combustion to catalyst combustion. More particularly, the shifting to catalyst combustion becomes possible while the feed of fuel and the flow rate of air are maintained in a constant level. The air flowing from the bypass 33 into the premixing chamber 26 through an opening 29 annularly opened passes through a space defined by a heat exchanging wall part 27' and the outer cylindrical wall of an air feed passage 28. In this instance, said air for combustion is preheated by the wall part 27' for a heat exchanger to flow into the premixing chamber 26, and is mixed with fuel fed through a fuel nozzle 36 to be converted into the premixed gas which is burnt at a catalyst body 20 in one combustion chamber 24 provided in the downstream of the premixing chamber 26. After heating the wall part 26' sand 27' of the premixing chamber 26, the burnt gas is discharged to the outside of a catalyst combustion device through an exhaust passage 27.
