Title: Synchronizing signal level detection circuit
Inventor: AMANO KUNIHIKO
IPC: H04N5/04
Filed: 1990-03-29
Abstract: PURPOSE:To detect a stable synchronizing signal level by using a detection signal of a synchronizing signal level with a peak hold means having a small time constant so as to detect a synchronizing signal and detecting the synchronizing signal level through a low pass filter having a larger time constant. CONSTITUTION:A synchronizing signal level of an input signal is detected by a peak hold circuit 44 having a small time constant and the synchronizing signal of the input signal is detected by a comparator 46 based on the synchronizing signal. Since the location of the synchronizing signal is nearly detected, the periodic signal period is widened up to the synchronizing signal period equivalently by sampling and holding 48 to the input signal (that is, the level of the synchronizing signal is held in this case), and the input signal is converted into a signal of only the synchronizing signal level. Since no undesired part such as a video signal exists in the input signal, the signal is given to a low pass filter 49 with a large time constant to average the signal level. Thus, the synchronizing signal level is stably detected.

Title: Light receiving circuit
Inventor: HORIKAWA SOJI
IPC: H04B10/00
Filed: 1986-04-08
Abstract: PURPOSE:To prevent the changing of a monitor output due to a temperature change by controlling the output temperature characteristic of a direct current- direct current converting device to supply a bias to a photoelectric transducer so as to show the characteristic corresponding to the temperature characteristic of the photoelectric transducer in an automatic gain control (AGC) circuit. CONSTITUTION:The temperature characteristic of the output voltage of a direct current-direct current amplifier 11 is constituted so as to be the same characteristic as the temperature characteristic of an avalanche diode APD1. When a temperature change occurs, the temperature characteristic of the APD1 and the direct current-direct current converting device 11 is compensated by an AGC function. For the temperature characteristic of the output of a low-pass filter 10, by comparing with the reference voltage having the corresponding temperature characteristic, the influence of the temperature characteristic is removed, and the output corresponding to the change only of a photodetecting power can be obtained based on the output of an error amplifier 17. By branching a part of the output of such an error amplifier 17 and giving it to a direct current amplifer 12, the change only of the photodetecting level can be monitored at a monitor terminal 13.

Title: Hydraulic shock absorber
Inventor: NEZU TAKASHI
IPC: F16F9/50
Filed: 1991-03-20
Abstract: PURPOSE:To select the extent of damping force according to acceleration acting on a hydraulic shock absorber. CONSTITUTION:When upward acceleration of more than the specified value acts on a hydraulic shock absorber at a contraction stroke, a weight 22 moves downward by dint of inertia force, a bypass passage 27 is opened so that damping force becomes lessened. On the other hand, an oil liquid in a cylinder lower chamber 3b pressurized at time of a contraction stroke passes through an orifice part 26 and flows into a small cylinder 17, thereby making a small piston 28 move against elastic force of a spring 29. Then, such a set weighting as energizing the weight 22 in a direction of closing the bypass passage 27 in proportion to travel of this small piston 28 grows larger. At this time, hydraulic pressure in the small cylinder 17 moving the small piston 27 has a vibration frequency dependency being determined by a damping coefficient of the orifice part 26 and an elastic coefficient of the spring 29, while the weight 22 is hard to move as set load become larger to a small frequency input, but it is easy to move as the set load becomes smaller to a large frequency input the other way.

Title: Temporarily stopping device for article carried on roller conveyor
Inventor: ISHIKAWA KAZUHIRO
IPC: B65G13/075
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent the deformation or damage of an article carried, which is caused when it is stopped for a time. SOLUTION: When an article carried is to be stopped for a time on a roller conveyor, a stopper 18, which stayed below the transferring surface, is raised before the article reaches the position of the stopper 18. At the same time with this action, two carrier rollers 6 standing behind the stopper 18 are stopped by a brake shoe 21. Accordingly, the article that was transferred toward the stopper 18 is brought into a brake-applied state when the article rides on the two carrier rollers 6 stopped. Thus, article slows dawn and it hardly collides with the stopper 18 violently.
