Inventor: SAITO KENJI
IPC: H04N9/11
Filed: 1995-02-27
Abstract: PURPOSE: To set a detection area and a control area in the white balance control of a video camera provided with the fetching function of negative film images by using the same light source as the one for the adjustment of a normal video camera. CONSTITUTION: By using plural ones whose color temperatures are different as reference illumination light, defining a difference between the maximum value and the minimum value of signals obtained at the time as a reference, 100% for instance, and storing the deviation amount of the detection value and the control value of chrominance signals in the case of photographing a negative film by the prescribed light source in a storage part 39 by a ratio to the difference, percentage display for instance, the color temperature detection area and the color temperature control axis of this automatic white balancing device of the respective video cameras are corrected by the ratio.

Title: Semiconductor rectifier diode
Inventor: SHIMIZU YOSHITERU
IPC: H01L29/861
Filed: 1982-03-12
Abstract: PURPOSE:To obtain the low-loss and high-speed diode, reverse blocking voltage thereof is approximately 200V, by forming p<+> layers, a space thereof is 14mum or less and thickness thereof is 12mum or less, to an n<-> layer on an n<+> type Si first layer. CONSTITUTION:An n layer 2 with approximately 15mum thickness is formed onto an n<+> type Si substrate 1 in an epitaxial shape, and the p<+> layers 3 with approximately 5mum thickness are formed through the selective thermal diffusion of B. B ions are implanted in the surface on the channel section 7 side surrounded by the p<+> layers 3 and annealed, and a p layer 4 with 2mum depth is formed. A Cr-Ni-Ag layer 5 is evaporated on the cathode side and an Al layer 6 on the anode side. In the diode with such structure, reverse blocking voltage rises because there is a p-n junction extending over the whole, and currents flow mainly through a p-n junction, potential incorporated therein is low, during the time when forward currents are small. When channel length is brought to 12mum or less, the high-speed diode, reverse recovery time thereof is 100ns or less, loss thereof is low (not more than 0.9V forward voltage drop) and withstand  voltage thereof is approximately 200V, can be manufactured with high yield.

Title: Re-entrant cylindrical resonator
Inventor: HIROYA HIKARI
IPC: H01P1/205
Filed: 1978-03-31
Abstract: PURPOSE:To obtain a re-entrant cylindrical resonator by which a desirable degree of coupling can be set freely, by providing a sectionally-flat center conductor which is longish in the direction connceting the center of a cavity to the coupling part. CONSTITUTION:Center conductor 15 with a rectangular section has longer side L in the direction connecting center line 3 of cavity 2 to antenna 12 and longer side W perpendicular to it. Intervals between opposite surfce 12A of antenna 12 and coupling window 14, and center conductor 15 decreases as the size of longer side L increases, and the degrees of coupling with coupling window 14 and antenna 12 increase. The increase in the degree of coupling with antenna 12 depends upon an increase in electrostatic capacity between the both, but the degree of coupling with coupling window 14 is caused by the concentration of an electromagnetic field at a part where the interval between conductor 15 and circumferential wall 6 becomes small. Consequently, only the change in the sectional shape of the center cnductor allows the degree of coupling with the outside to increase. As a result, the coupling part of the antenna, etc., can be set easily and a filter of required characteristics can be obtained easily.

Title: Motor controller for record player
Inventor: KITAJIMA MASARU
IPC: H02P29/00
Filed: 1979-03-30
Abstract: PURPOSE:To maintain the speed of the motor at a constant level eliminating variation in the angular velocity by controlling the rotation thereof with the voltage obtained from the comparison of the proportional voltage and the error voltage with the reference voltage. CONSTITUTION:A frequency S90 deg. shifted in the phase by 90 deg. from the frequency S0 deg. proportional to the rotational frequency of the motor M is obtained from a velocity detector SD. The frequency S0 deg. is converted into a proportional voltage with a frequency-voltage converter FV while compared and combined with the reference frequency S0 by means of a multiplier M2 to produce the output S1. At the same time, the frequency S90 deg. is compared and combined with the reference frequency S0 by means of a multiplier M2. An error signal S1A is obtained by passing the output S1 through the LPF1 while an error signal is obtained by shifting the output S2 by 90 deg. with a shift circuit SFT via the LPF2. The error signals S1A and S2B are proportionally combined with a multiplier M3 to produce the output S3, which is passed through the LPF3 to obtain the error signal S3A. The error signal S3A is processed with an integrator INT to obtain an error voltage E2. After the voltages E1 and E2 are added with an addition circuit ADD, the voltage obtained from the comparison between the resulting voltage and the reference voltage Er serves to control the rotation of the motor M to a constant level.

Title: Polarization light source device
Inventor: NAKAYAMA TADAAKI
IPC: G09F9/00
Filed: 1990-02-20
Abstract: PURPOSE:To efficiently convert light radiated from a light source lamp into linearly polarized light and to emit the light by forming an angle of 45 deg. with the main cross section of a lambda/4 wavelength plate and the polarization plane of lenearly polarized light reflected from a polariscope. CONSTITUTION:The angle formed by the main cross section of the lambda/4 wavelength plate and the polarization plane of a linearly polarized light reflected from the polariscope 15 is 45 deg.. After non-polarized light emitted from a light source device passes through the lambda/4 wavelength plate 14, the linearly polarized light is extracted by the polariscope 15. Linearly polarized light intersecting orthogonally with this linearly polarized light is reflected in the light incident direction and its opposite direction by the polariscope 15, and again passes through the lambda/4 wavelength plate to be circularly polarized. This circularly polarized light is reflected by a reflector in the light source device to be circularly polarized in the opposite direction. This light passes again through the lambda/4 wavelength plate 14 to be linearly polarized. At this time, the polarization plane of the linearly polarized light is intersected orthogonally with the polarization plane obtained when the light is reflected by the polariscope 15, therefore the light is emitted in the same direction and with the same plarization plane as those of the linearly polarized light extracted first after the light is again made incident on the polariscope 15. Since all the non-polarized light emitted from the light source device is converted into the linearly polarized light and used, the coefficient of utilization is increased.

Title: Optical waveguide
Inventor: NAKAGOME SEIJI
IPC: C08F8/00
Filed: 1990-02-20
Abstract: PURPOSE:To enhance a self-shape holding property by forming a core material and clad material of a high-polymer material having a three-dimensional crosslinked struc ture with the glass transition temp. of room temp. or below and rubber-like elasticity and forming a clad material coating layer of a high-polymer material having a three- dimensional crosslinked structure of a specific glass transition temp. CONSTITUTION:Both the core material and the clad material consist of the high- polymer material of the three-dimensional crosslinked structure with the glass transition temp. of the room temp. or below and the rubber-like elasticity and the clad material coating layer is constituted of the high-polymer material having the three-dimensional crosslinked structure of 40 to 80 deg.C glass transition temp. (Tg). The coating material of the high-polymer material having the three-dimensional crosslinked structure is limited to the 40 to 80 deg.C range of the glass transition temp. (Tg), but the Tg is required to be >=40 deg.C in terms of the shape holding thereof when the material is used at the room temp. (about <=30 deg.C) or below. On the other hand, the reason for limiting the Tg to <=80 deg.C lies in that the heating up to a high temp. at every time of deforming of the material is difficult if the temp. is above the limited range. The optical waveguide itself can maintain its specific shape in this way.
