Title: Optical imformation recorder and reproducing device
Inventor: WAKAMI NOBORU
IPC: G11B7/09
Filed: 1983-03-18
Abstract: PURPOSE:To perform excellent recording and reproducing even on a highly warped optical disk, by installing a detecting means which detects the condition of a light beam irradiated almost verticaly upon the information recording surface of the optical disk by a deflecting means which deflects the optical beam in the direction of the radius of the optical disk. CONSTITUTION:A tracking driving means 13 is driven through a tracking driving circuit 23 by inputting a signal B of a sawtooth-like wave into a signal adding circuit 22 and a movable bodytube 10 is started to turn. At this time, a tracking error signal obtained from a tracking light detector 9a is taken into a microcomputer 25 through an AD converter 24 and the difference in the tracking error signal before and after the movable lens bassel 10 is turned is operated. The value of the signal B is maintained at a level reached when the difference just starts to decrease and the turning of the lens barrel 10 is stopped. When such a constitution is used, the movable lens barrel 10 is held at a location where the lens barrel is turned for an angle theta, and therefore, the light beam is corrected so that it is irradiated upon the disk surface vertically and an excellent tracking condition is obtained.

Title: Method of controlling braking pressure of anti-lock car brake-system
Inventor: FUORUKAA BURASHIERU
IPC: B60T8/172
Filed: 1989-02-27
Abstract: PURPOSE: To enhance the braking characteristic in a device for comparing the control magnitude decided on the basis of a wheel slip or the like to a limit value so as to increase or decrease the brake fluid pressure by variable setting a limit value in response to a deviation of the control magnitude in relation to the predetermined set value. CONSTITUTION: At the time of operating a brake, a slip ΔV as a difference between the velocity Vw and the reference speed Vr of a wheel is obtained as a control magnitude in a block A, and this ΔV is stored in a peak value memory B in the downstream side. A peak value stored in a block C is compared with the predetermined set valve Sw, and when the braked wheel is changed from the stabilized condition to the unstable condition, a switch S2 is closed, and a limit value or the filtering time is adjusted in a block D. The limit value is adjusted on the basis of the deviation value of the control magnitude from the predetermined set value Sw, and the brake liquid pressure is controlled for increase or decrease in response to a result of the comparison of the obtained limit value with the control magnitude.

Title: Combustion control device for multi-cylinder engine and its method
Inventor: ATAGO TAKESHI
IPC: F02P5/15
Filed: 1989-03-01
Abstract: PURPOSE:To reduce a scattering in output by each cylinder by obtaining the fluctuating condition in engine revolution by each cylinder, and thereby controlling a regulation means regulating the ignition timing or the quantity of fuel injection in response to the fluctuating condition. CONSTITUTION:When an engine is in operation, the basic quantity of fuel injection is computed by a control unit 12 based on the quantity of suction air and an average engine revolution. Then, the engine revolution Ne is measured by making use of POS signals from a revolution detecting sensor 6. The basic ignition timing thetaig is obtained depending on the basic quantity of fuel injection and the average engine revolution by means of map retrieval, and the maximum value Nmax of the engine revolution Ne and the angle thetan at the time of the maximum engine revolution are thereby computed. Then, thetanmap is searched for by making use of Nmax and the average engine revolution. When DELTAthetan (= thetan through thetanmap) is positive (negative), a correction lead angle is increased (decreased) by a definite angle.

Title: Frequency control method for inverter
Inventor: KANIE TETSUO
IPC: H02P27/06
Filed: 1991-03-12
Abstract: PURPOSE:To improve frequency control for inverter. CONSTITUTION:Power of a three-phase AC power supply 1 is fed through a noise filter 2 and converted through a converter 3 into DC power which is then fed through a reactor 4 and a smoothing capacitor 5 and inverted through a switching element section 6 into AC power to be fed to a motor. The switching element section 6 is switched through a driving circuit 8 based on a command delivered from a control circuit 9 comprising a CPU 10 and a memory 11. The memory 11 contains a data table previously stored with waveform data for each operating frequency. The control circuit delivers a command, based on the waveform data for each operating frequency stored on the table, to the driving circuit 8. For an operating frequency not stored on the table, data on the table closest to that operating frequency is utilized for driving the switching element section 6 with time ratio of waveform pattern being varied. At that time, variation width of the operating frequency is decreased immediately before or after modification of the waveform data whereas it is increased during modification.

Title: Pin ball game machine having continuous service
Inventor: FUKUSHIMA SEIICHIRO
IPC: A63F7/02
Filed: 1989-02-28
Abstract: PURPOSE:To enable expectation of effective utilization of a specified game state by a method wherein when a specified game state is entered, an interval at a point of time when the number of times which a continuous service is continuously actuated amounts for approximately half an upper limit value is set to a value longer than other intervals. CONSTITUTION:When there is, for example, a V prize memory, it is decided whether a value of the upper limit number of counting times is '5'. When the value of the upper limit number of counting times is '5', since the number of times is a value being approximately half the allowable upper limit number of times, before the progress to a subsequent opening state is made, rest processing is effected so that a rest time having a relatively long interval is taken. Digital display devices 9a-9c start variable display in relation to a game, after elapse of a specified time, the devices are automatically stopped. When a display form during a stop is a specified display form, a motion is continued, but when it is not a specified display form, a specified game state is completed at a current point of time. In this case, by sharply increasing probability of display of the specified display forms of the digital display devices 9a-9c, there is much possibility for subsequent continuance, and amusement of a game player is further increased.

Title: Metal gasket
Inventor: YOSHINO NOBUO
IPC: F16J15/08
Filed: 1987-03-03
Abstract: PURPOSE:To make it possible to stably seal an engine by forming a bead in a base plate made of a resilient metal plate, surrounding each combustion chamber hole, and by folding back the base plate so as to form a compensating part in the base plate, at a position nearer to the combustion chamber hole than that of the bead forming part so as to compensate the gap between deck surfaces. CONSTITUTION:In order to compensate irregularity in the gap between deck surfaces 18a, 20a, which is formed between a cylinder head 18 and a cylinder block 20 that are fastened together, a base plate 4 is fold back so as to form a compensating section 14 having a fold-back abutting part 12 whose width is greater than that of a fold-back gap 10 at a position nearer to a combustion chamber hole 6 than a position where a head 8 is formed surrounding the combustion chamber hole 6. Accordingly, the metal gasket may be held stably without the deck surfaces 18a, 20a being damaged. Further, due to the provision of the compensating section, it is possible to prevent combustion gas from entering through the gap between the deck surfaces 18a, 20a having a large area around each combustion chamber so as to weaken alternate load exerted to the bead 8. Further, since the compensating section 14 is formed with no other member being provided on the base plate 14, the arrangement is made to be simple, thereby it is possible to facilitate the manufacture thereof.
