Title: Compensating circuit of optical pulse width
Inventor: YAMAGATA MATAZOU
IPC: H04B10/00
Filed: 1981-09-16
Abstract: PURPOSE:To set the optical pulse width at a certan value, by controlling the quantity of a phase circuit in accordance with a change of a DC bias current of a laser diode. CONSTITUTION:The pulse signal of the voltage EO is supplied to an NAND gate  2, and at the same time the signal of the same waveform which is delayed by time taud1 is supplied to the gate 2 via a phase circuit 1. The pulse signal having a width increased by taud1 through the gate 2 is applied to the base of a transistor TR33. The reference voltage VO is set lower than the voltage EO, and as a result the base potential of the TR33 is higher than the potential VO at a point A. Then the TR33 is turned on, and the current path of a constant current source 35 is switched toward the TR33. In this case, an amplified current having the same waveform as the control signal applied to the base is supplied to the collector of the TR33. While a current obtained by adding a bias current IB to the collector current of the TR33 is supplied to a laser diode 31. As a result, an optical output which has the same width as the input signal and is delayed by time taud1 to the current IB is oscillated from the diode 31.

Abstract: PURPOSE: To perform exposure correction while viewing the finder by changing the correct exposure information having been stored in a register, step by step, by a logarithmic extension circuit and the automatic reset type 2-contact switch mounted to the camera outside.  
     CONSTITUTION: When the photographer judges by viewing the finder visual field that exposure correction needs by performed, he pushes the exposure correction switch 7 of automatic reset type 2 contacts once to the + side or - side, then a CPU 3 emits a shift instruction to a memory 9 which has stored correct exposure information. When the memory 9 upon receiving this shifts the storage contents by 1 bit to the upper position, the exposure time is changed of setting to the value of 1/2 time by the operation of a logarithmic extension circuit 11 and when it shifts to a lower position, the exposure time is changed of setting to the value of 2 times. Hence, when the switch 7 is pushed n times, the contents of the memory 9 in which the exposure time is corrected to 2 n  times or 1/2 n  times are displayed in the shutter second time portion of the finder 15 and the exposure correction may be performed while the photographer is viewing the finder.

Title: Control device for power take-off gear
Inventor: HIROSE YOSHITO
IPC: B60K25/06
Filed: 1991-05-21
Abstract: PURPOSE:To prevent the occurrence of a gear noise, gear fracture or the like at the time of turning on PTO(power take-off system) by connecting a speed switch, a PTO switch, a time lag switch and three-way magnet valve in series to a clutch switch. CONSTITUTION:When a clutch is disengaged (i.e., clutch switch 01 off) with a PTO switch 02 kept on, the contact of a time lag relay 2 does not immediately turn on for a few seconds after releasing the clutch, and turns on only after the elapse of a delay time. Also, a PTO gear becomes engaged with the clutch via a three-way magnet valve 03, due to the actuation of the time lag relay 2. In this case, a counter shaft stops a concurrent turn and comes to rest during the delay time. Consequently, the occurrence of gear noise and fracture can be prevented. Also, even when the PTO switch 02 is tuned on immediately before the stop of the counter shaft, the PTO gear does not become engaged, because a speed switch 1 is turned off, thereby preventing the occurrence of gear noise and fracture as well.
