Title: Optical output control circuit for laser diode module
Inventor: OKAMOTO AKIRA
IPC: H01S5/068
Filed: 1986-03-20
Abstract: PURPOSE:To prevent the forward output light of a laser diode element from being changed even when the dark current of a photodetector is changed by detecting the AC component in the output current of the photodetector and controlling the optical output so that the magnitude of the AC component is constant. CONSTITUTION:A bias source and bias modulator 6 gives a photodetector 3 a prescribed DC bias voltage and modulated signals with an arbitrary frequency and a constant amplitude which are superposed on the bias voltage by the bias modulator. The AC component of monitor output current, applied to an AC component detecting circuit 7, is detected thereby. The AC component signals are applied to an automatic output power control (APC) driving circuit 4, compared with a reference value, a driving signal is produced in accordance with an error to operate a laser diode (LD) element 2 and a feedback control is conducted so that the magnitude of the AC component signals is constant. In this case, even though the dark current of the photodetector is changed, the AC component of the monitor output current is not changed and therefore the light output of the LD element 2 is not changed.

Title: Continuously variable transmission
Inventor: MATSUMOTO HIDEKI
IPC: F16H9/12
Filed: 1988-03-18
Abstract: PURPOSE:To reduce the operating force on the speed change operation in the title transmission by securing an intermediate pulley with a movable shape in a counter form having such a structure as to be axially moved by a speed change switching mechanism and rotatably supporting a ring on the bottom of a pulley part of the intermediate pulley between the driven pulley and the same. CONSTITUTION:Under the engagement between a cam groove 17a of a cam member 17 and a roller 18 in a speed change switching mechanism 14, a movable shape 10 is axially shifted so as to change an effective radius of the first and second pulley parts 11, 12. This causes the movable shape 10 to be driven with a small force, thereby reducing an operating force on speed change operation. Since the movable shape 10 is connected to the cam member 17 through a bearing 16, the resistance between the cam member 17 and the movable shape 10 on the turning operation is smaller, thereby furthermore reducing the operating force. In addition, in the transient state of riding of the second V belt B2 on the ring 22, the contact area of the V belt B2 to the second fixed shape 9 is smaller, thereby more smoothly shifting to a neutral state.

Title: Pinball machine
Inventor: MATSUBARA NOBUO
IPC: A63F7/02
Filed: 1991-03-05
Abstract: PURPOSE:To provide a pinball machine capable of controlling the variation stop of a pattern display according to the appearance probability of a big prize pattern so that neither disadvantage nor discontent is brought about both on the amusement place side and on the player side. CONSTITUTION:A pattern display 13 provided in the game board 1 of a pinball machine can display variation according to the low and high probability modes of the appearance probability of a big prize pattern. After starting of variation, the variation is stopped by the lapse of a given time through a timer in the low probability mode and the variation is also stopped by pushing down of a timer or stop switch 28 before the lapse of a given time through the timer in the high probability mode. Thus, it becomes impossible to intentionally cause a bitg prize pattern to appear by considering the periodicity of a pattern variation in the low probability mode and it is possible to shorten a bariation time and to reduce the number of useless starting prizes in the high probability mode where there is little necessity for intentionally causing the big prize pattern to appear.

Abstract: PURPOSE:To easily detect three-dimensional displacement by obtaining attenuation characteristics of waves and directional characteristics of a wave receiver, then obtaining a distance in a wave direction and displacement within a wave received plane with signals from a first wave receiver and adding signals from other receivers to separate the in-plane displacement. CONSTITUTION:Directional characteristics of a wave sender 11 and wave receivers 13a, 13b, 13c and attenuation characteristics with respect to a distance are obtained in advance. Delay time when the wave sender 11 is received by the wave receivers 13a, 13b, 13c is T+DELTATa, T and T+DELTATc, respectively, while an attenuation amount at the wave receiver 13b is DELTAV. The delay time T is converted into a distance rb, wherein difference from a reference position r0 is calculated to obtain displacement DELTAr in a wave propagating direction. In addition, DELTAV is compared with an attenuation amount DELTAV0 from distance- attenuation characteristics to obtain an angle theta from the directional characteristics. Separation in Y-Z in-plane displacement is possible with respect to arbitrary motion by analyzing a relative change in delay time difference DELTATa, DELTATc of the wave receivers 13a, 13c.

Filed: 1990-03-16
Abstract: PURPOSE:To avoid a trouble of seeking a file reservation list later for the operator leaving an outputted file reservation list as it is by devising the output system such that a final transmission original is discharged after the file reservation list is outputted. CONSTITUTION:While a recording section 2 records a received data, a transmission original is inputted to a file memory section 10, and when the input is finished, a stop means 12A stops tentatively the discharge of the final page of the transmission original by an automatic document feeder section 13. Then, the reception recording is interrupted, a file reservation list is outputted which is reserved by a file management section 11 between pages of the recording paper, the final transmission original is discharged and then the reception recording is restarted. Thus, the final transmission original is discharged after the file reservation list is outputted, then the operator does not forget the extraction of the outputted file reservation list but is surely accepted and a trouble of seeking the list later is avoided.

Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To restore the charging value of a sample holding capacitor to a steady value even if the charging value is changed in a sample holding period by a method wherein the ON/OFF of a charging current applied to the sample holding capacitor is controlled by the output of a comparator consisting of a capacitor and an inversion amplifier.
