Title: Cavitation preventing device for hydraulic cylinder
Inventor: TAJI HIROSHI
IPC: E02F9/22
Filed: 1992-01-16
Abstract: PURPOSE:To prevent occurrence of cavitation in an arm cylinder upon reduction of the main discharge hydraulic oil volume, by providing a poppet valve in a return passage of a pilot selector valve for passing return oil therethrough from a hydraulic cylinder when hydraulic oil is fed into a load side oil chamber of the hydraulic cylinder. CONSTITUTION:When an engine for a hydraulic shovel is rotated at a high speed so as to shift a working manipulation lever 6 to an arm pulling position, a pilot pressure is applied to a pilot pressure receiving part 10 through a pipe line 44, a spool 13 in a pilot selector valve 9' is moved leftward, and a passage selector valve 23 is changed over to a position (b). Accordingly, oil discharged from a main pump 16 is fed into a bottom side chamber 4 and an arm cylinder 3 pulls an arm. Meanwhile, during pulling of the arm in a lower engine rotational speed range, the discharged hydraulic oil flow volume is less and a poppet 36 in a cavitation preventing valve 21 restricts a return oil passage 15', and accordingly, the return oil from a rod side oil chamber 5 is inhibited from being discharged, and, it is possible to prevent occurrence of cavitation.

Title: Discharge lamp lighting device
Inventor: SUGINO MOTOHIRO
IPC: H02M7/48
Filed: 1994-02-24
Abstract: PURPOSE:To prevent extinction of a discharge lamp in the final period of lifetime and also its running temperature by controlling the duty ratio of the lighted period and turned-off period so that the mean value of the power supplied to the discharge lamp becomes constant. CONSTITUTION:The switch element current sensing voltage generated in a current sensing resistance 10 is passed through a low pass filter 11 to determine the mean value of the switch element current, and the obtained value is compared with the target voltage value Vref by a comparator 12. When the reference value Vref is exceeded, the output voltage value of the comparator 12 is lowered, and the duty ratio of the output signal of a PWM circuit 13 is lessened. In other case, the duty ratio is enlarged. By an AND gate 15, the output frequency of an oscillator 14 is supplied to a switch element driving circuit 16 only when a PWM signal is Hi, and current flows to switch elements 2-5 during the Hi period of PWM signal, and the mean value is controlled constant. Because the supply voltage is constant, the power to the lamp 9 connected to the secondary side of trunks is proportional to the constant primary current I1 of the trunks, so that supply voltage to the lamp 9 becomes also constant.

Title: Test signal generator for color camera
Inventor: ADACHI YUKIHIRO
IPC: H04N17/02
Filed: 1985-02-15
Abstract: PURPOSE:To obtain high reliability with a cheap and simple construction by forming a test signal to be fed to a signal processing circuit in a color camera based on an output signal from an oscillating circuit in which an oscillation is controlled by a drive signal of an image pickup means. CONSTITUTION:A carrier oscillating circuit 2 has a multi-vibrators and a gate for controlling start/stop of oscillation is incorporated in a part of this multi-vibrator. To this gate, a horizontal drive signal is inputted. Base on this signal, the oscillation generated from the carrier oscillating circuit 2 is controlled by a level of the horizontal drive signal 1. When a drive of the horizontal drive signal 1 inputted to the gate is a low level L, the oscillation is stopped, and when it goes to a high level H, the oscillation is started. Judging from the characteristic of the multi-vibrator, the level and cycle of the first 1 pulse of a carrier starting to oscillate and outputted are substantially the same as those of a normal condition in which the oscillation is stabilized and a rise polarity becomes the same every time the oscillation is started.
