Title: Chroma signal processor for veneer color camera
Inventor: OZAWA NAOKI
IPC: H04N9/07
Filed: 1987-10-09
Abstract: PURPOSE:To simplify a chroma signal processing circuit by mixing luminace signals into chroma signals obtained from the outputs of subtraction circuit in two horizontal scanning periods at an arbitrary ratio in the separation circuit separating the output signals of an image pickup element and in the subtraction circuit subtracting the separated picture element signals at the arbitrary ratio, and directly obtaining color difference signals. CONSTITUTION:When the gain of addition signals S1 is set to '1', the gain a1 of addition signal Sa becomes smaller than '1'. Consequently, the output signals of separation circuits 121 and 122 are added to amplifiers 131 and 132, for example, and the gain of the amplifier 131 is set to 1+a1 and that of the amplifier 132 to 1-a1. The output signals of the amplifiers 131 and 132 are added to the subtraction circuit 141 and the obtained signals are band-restricted in a low pass filter 151, whereby they are delayed in a 1H delay circuit 161 for one horizontal scanning period. When the output signals of the low pass filter 151 and the 1H delay circuit 161 are added in an addition circuit 181, the color difference signals CB can be obtained. Thus, the color difference signals can be obtained by gain-adjusting the amplifiers 131 and 133, or the amplifiers 132 and 134.

Title: Information recording and reproducing device
Inventor: ISHIKA TAKESHI
IPC: G11B11/105
Filed: 1989-09-29
Abstract: PURPOSE:To miniaturize an optical head, to simplify assembly and adjustment and to stably detect a light beam by setting the plane of polarization of the light beam from a light source so that it makes a specified angle against a reference axis on the light source with respect to the polarizing direction of the light beam separated by a separation means. CONSTITUTION:A non-polarizing light beam split surface (m) is used as the separation means for the light beam generated from a semiconductor laser element 2 and the plane of polarization of the light beam generated from the laser element 2 is rotated by about 45 deg., for example, against the reference axis included in a plane parallel with a direction where the light beam is transmitted on the polarizing light beam split surface for separating the light beam and making it incident on photodetectors 26 and 28, that is, a Y-axis. Therefore, a 1/2lambda plate for making the transmittivity of the P polarization component of the light beam and the reflectance of the S polarization component constant and a rotation adjusting mechanism for adjusting the rotation with respect to the optical axis of the light beam can be eliminated. Thus, the device has simple constitution and stable characteristic, it is miniaturized and the easy assembly and adjustment of the device are accomplished.

Title: Heterojunction bipolar transistor
Inventor: TABUCHI TOSHIHIRO
IPC: H01L29/16
Filed: 1987-10-07
Abstract: PURPOSE:To enhance a current gain by using fine crystal silicon in an emitter layer. CONSTITUTION:Micro crystal silicon (muc-Si) is used in an emitter layer of a silicon heterojunction bipolar transistor. Because conductivity of the muc-Si is very high, a carrier is high, a resistance value is low, and a carrier density is high; accordingly, many electrons are injected into a base from an emitter. In addition, because the muc-Si does not contain atoms of a different species such as a carbon of a-SiC:H, a localized level density due to a lattice strain is not increased. However, muc-Si:H discussed here is a structure containing a micro crystal phase in amorphous silicon. By this setup, a current gain is enhanced.

Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To improve the resonance effect of a diaphragm by specifying the thickness of the diaphragm in a machine in which a vibrator is attached to the diaphragm, the vibrator is driven by an ultrasonic wave generator. SOLUTION: In an ultrasonic cleaning apparatus using an ultrasonic vibrator which gives ultrasonic vibration to cleaning liquid for cleaning semiconductor wafers etc., the cleaning liquid is supplied to a pair of supply routes 31, a vibrator 24 is driven by an ultrasonic vibration generator to vibrate a diaphragm 21 ultrasonically. The cleaning liquid supplied to the supply route 31 is distributed into ejection routes 32 to be ejected from the other end openings of the ejection routes 32 toward the diaphragm 21. When the cleaning liquid ejected from each ejection route 32 collides with the lower surface of the diaphragm 21, the ultrasonic vibration is propagated to the liquid. The thickness of the diaphragm 21 is set up to be less than 0.1mm to obtain a high effect of resonance with the vibrator 24.  In this way, the diaphragm 21 is made to resonate with the vibrator 24, the attenuation of the vibration is restrained to be able to give strong ultrasonic vibration to the cleaning liquid.
