Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to compensate for a stabilized operation over a long time by lubricating properly an engagement area between an pinion and an inner wheel of a swivel wheel or the like all the time. SOLUTION: A grease receiver projection 33 and a grease scraping out projection 37 are provided on the lower end of a housing 31 of a swivel motor where the grease receiving projection 33 is designed to prevent the grease which drops near the top of an inner wheel 4 and extends and is pushed out from an engagement area between the inner wheel 4 and a pinion 29 from flowing in the outward and radial direction of the inner wheel 4 and the grease scrape out projection 37 is designed to scrape out the grease remaining in the pinion 29 and the inner peripheral surface 30A of the grease pass 30.

Title: Signal processor
Inventor: KITAGAWA SHIYUNJI
IPC: G06K7/10
Filed: 1981-09-30
Abstract: PURPOSE:To stabilize the output signal of a waveform shaping part by inputting the output of a subtracting circuit to the control input terminal of a voltage gain control amplifying circuit and then controlling the gain of the amplifier. CONSTITUTION:An input signal to an input terminal 1 is amplified by a voltage variable gain amplifier 2, whose output is supplied to an upper envelope circuit 5 and a lower envelope circuit 6. The circuit 5 detects the upper envelope of the output signal of the amplifier 2, and the circuit 6 detects the lower envelope. The upper envelope waveform and lower envelope waveform inputted to a subtracting circuit 13 are processed by subtraction, and the difference signal is supplied to the control input terminal 22 of the voltage gain amplifier 2 through a low-pass filter 19. Namely, the signal obtained by cutting the high frequency component of the output of the subtracting circuit 13 is applied to the terminal 22 of the amplifier 2. Consequently, the gain of the amplifier 2 varies with the voltage applied to the terminal 22; the gain is low when the input voltage is low and high when the voltage is high.

Title: Electronic still camera
Inventor: OGAWA HIDEHIRO
IPC: H04N5/765
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To display a monitor image of an object onto a display device even when object luminance is low and it gets dark by lighting the object to pick up an image of the object with an image pickup element, storing the picked-up object image to a storage means and displaying the image onto the display device. SOLUTION: Storage of charge by a CCD 7 is started and a speed light 5 is lighted for the storage period synchronously with the storage. Thus, a dark object is lighted by the speed light 5 so as to allow the CCD 7 to store an object image with sufficient luminance. Then the picked-up object image is stored in an image memory 11 and displayed on an LCD 2 as a still image. Whether or not a release switch 4 is half-depressed is confirmed. When the switch 4 is half-depressed, the display of the tentatively picked-up image by the LCD 2 is finished and the tentatively picked-up image data stored in the image memory 11 are deleted. Then the moving image reproduction mode is restored and a usual image is displayed on the LCD 2.

Title: Data pulse reproducing circuit for magnetic disk device
Inventor: NARITA TERUYUKI
IPC: G11B5/09
Filed: 1990-06-14
Abstract: PURPOSE:To prevent an omission in a data pulse at the part of a signal amplitude decreased from a constant amplitude due to the delay of an AGC flow-up by holding successively the peak value of the waveform amplitude of an AGC output as a slice level signal, and preparing the data pulse from the peak part of an AGC output waveform exceeding this peak holding value. CONSTITUTION:This circuit is equipped with a peak holding means 20 which holds successively the peak value of the AGC output signal, and outputs the peak value to a gate signal preparing means 16 as the slice level signal. At this time, the AGC output signal inputted to a differentiation circuit 14 and a gate signal preparing means 16 against the AGC output signal inputted to the peak holding means 10 is delayed in the prescribed time so that the peak holding means 20 can precede the differentiation circuit 14 and the gate signal preparing means 16. Then, the differentiation circuit 14 differentiates the AGC output signal, and the peak holding means 20 holds successively the peak value after rectifying the AGC output signal and converting it to a unipolar signal waveform. Thus, the gate signal corresponding to the amplitude peak part can be certainly prepared, and the omission in the data pulse can be surely prevented.
