Abstract: PURPOSE:To ameliorate an operating lag in a control valve as well as to prevent a steering lag in a handle wheel from occurring, by making a controller so as to open or close a compensation pressure relief valve according each signal out of a car speed sensor and a steerage sensor. CONSTITUTION:A pair of compensation pressure supply passages 22 and 23 connect compensation steering pressure chambers 51 and 52 of a compensation steering valve 21 to an accumulator 20, leading the high pressure stored in this accumulator 20 into these compensation steering pressure chambers 51 and 52, whereby the compensation steering valve 21 is made so as to be slidden in design. These compensation pressure supply passages 22 and 23 set up compensation pressure throttles 97 and 98 whereby pressure oil is made easily escapable from these pressure chambers 51 and 52 by way of compensation pressure escape passages 24 and 25. These passage 24 and 25 make the pressure oil so as to escape to an oil reservoir from these compensation steering pressure chambers 51 and 52 in design. These compensation pressure relief valves 26 and 27 are driven by an output current out of a controller 28.

Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To ensure a stabilized control by measuring the time interval between variation of a signal derived from a signal detected by specific one of a plurality of position detecting elements and variation of the next signal thereby suppressing generation of an error contained in a conduction overlap time. SOLUTION: A signal variation time interval measuring means 3 measures the signal variation time interval between variation of a signal obtained from a signal detected by a specific one Hu of a plurality of position detecting elements 2 (Hu, Hv, Hw) and variation of next signal. A conduction overlap time calculating means 4 calculates a conduction overlap time corresponding to a predetermined electric angle based on the signal variation time interval at that moment. The Qu<-> ,..., Qw<+> of a switching element 7 provided with a signal from a microcomputer 8 are conducted by being supplied with a base current in the direction and the order of stator windings dependent on the state of the position detection signal. Conduction timing can be regulated optimally by altering the on/off timing of the switching element arbitrarily.

Title: Pachinko game machine
Inventor: SATO FUMIAKI
IPC: A63F7/02
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To increase expectation imparted to a player and improve interest by providing a probability indicator displaying a plurality of patterns when a possibility of getting a special prize exists after a reach during a pattern varying game to be stopped after patterns are varied and displayed by a pattern fluctuation indicator. SOLUTION: When a game ball enters a starting hole during a Pachinko game (Japanese pinball game), patters of indicators L1 to L3 are fluctuated via a controller and the patterns of the indicators L1 to L3 are successively stopped after fixed time elapses. Because a possibility of getting a special prize exists when the patterns of the indicators L2, and L1 are matched at this time, display parts 63a to 63c formed by three LEDs in a probability indicator 63 are made to display patterns to be displayed on the indicator L3 which is lastly fluctuated and stopped. Thus, a player knows a probability of a pattern to be stopped by the indicator L3 and plays a game in a state that expectation and anxiety are mixed, while comparing fluctuated figures of the indicator L3, and interest for players is increased.

Title: Rack and pinion mechanism
Inventor: SUDA HARUO
IPC: F16H55/28
Filed: 1989-09-29
Abstract: PURPOSE:To adjust backlash arbitrarily by forming all of rack teeth so as to be tapered teeth having variable tooth thickness which increases from one side of the rack toward the opposite side, and also by forming all of pinion teeth so as to be tapered teeth having variable tooth thickness which decreases from one side of the rack toward the opposite side. CONSTITUTION:All teeth 11 of a rack 10 are formed so as to be tapered teeth, whose tooth thickness increases from one side of the rack 10 toward the opposite side making an equal lead taper angle theta on both flanks. A pinion 20 has plural teeth 21 on its outer periphery which are to be engaged with the teeth 11 of the rack 10 and have a conical section of an involute profile on both sides. All teeth 21 of the pinion 20 are formed so as to be tapered teeth, whose tooth thickness decreases from one side of the rack 10 toward the opposite side and have an equal lead taper angle on both flanks. This taper angle is nearly equal to the taper angle theta of the rack 10. Consequently, backlash between the rack 10 and the pinion 20 can be adjusted by shifting the pinion 20 in its axial direction in a state where a center distance (h) between a axial line O of the pinion 20 and the center of the rack 10 is kept constant.

Title: Mel type crystalline metallosilicate and its production
Inventor: OKU TOMOHARU
IPC: B01J20/18
Filed: 1999-09-09
Abstract: PROBLEM TO BE SOLVED: To obtain fine particles of the subject metallosilicate having small primary particle size by efficiently introducing trivalent metal ions into the crystal lattices while shortening a crystallization time so that the outer surface area of the crystal, which is obtained by a mercury press-injecting method, is made into a specified value or larger and the average primary particle size is made into a specified value or smaller. SOLUTION: This metallosilicate has 50 cm3/g or larger outer surface area of the crystal and 0.1 μm or smaller average primary particle size. The production method of such a metallosilicate comprises a process for drying a water-soluble slurry starting material composition consisting of a trivalent metal salt, a silica source, a tetra-n-butyl ammonium salt and an alkali metal source to obtain a precursor and bringing the precursor into contact with saturated steam to crystallize metalosilicate. The temperature of the saturated steam is preferably made to 70-240 deg.C. The crystallization time can be remarkably shortened when the metal salt of boron, aluminum, chromium, iron or gallium is used as the trivalent metal salt. As the tetra-n-butyl ammonium salt, its hydroxide is preferably used.  This metallosilicate is suitable particularly as a catalyst or an adsorbent when the mass transfer into the crystalline particles by diffusion affects the catalyst activity.

Abstract: PURPOSE:To obtain the control over a wide range of a car speed for a delay time by making the surface detecting position of a road surface detecting sensor variable, by adjusting either the delay time or sensor moving quantity for an actuator on the front wheel side, and by adjusting the delay time on the rear wheel side, so that the damping force variable signal can be outputted separately. CONSTITUTION:A front wheel 2 and a rear wheel 3 are provided with shock absorbers 20, 20' having a damping force variable device and suspensions 5, 5' equipped with motors 7, 7' which can control/vary the damping force. In addition, a road surface sensor 10, which can detect the irregularity of the road surface, is installed in the forward, lower part of a car body 1 in such a manner that the sensor 10 can be moved forward from the vicinity of the front wheel 2 so as to vary its road surface detecting position. The signal from the road surface sensor 10 and a car speed sensor 13 is processed by a control unit 14. With regard to the motor 7 of the front wheel suspension 5, the delay time or sensor moving quantity is adjusted in correspondence to the car speed, while, with regard to the motor 7' of the rear wheel suspension 5', the actuation is delayed by the delay time for the entire range of the car speed. Thus, the damping force variable signal corresponding to the irregularity of the road surface can be outputted separately.
