Title: Production of hexagonal boron nitride sintered body
Inventor: OGAWA TAKASHI
IPC: C04B35/583
Filed: 1988-04-25
Abstract: PURPOSE:To enable sintering under normal pressure and to obtain a dense hexagonal BN sintered body having high purity and stability by adding a precursor monomer having a B-N bond as sintering aid to hexagonal BN powder and executing sintering of the mixture. CONSTITUTION:A precursor monomer having a B-N bond is added to hexagonal BN powder as sintering aid. Concrete examples for the precursor monomer having a B-N bond are B-triamino-N-triphenyl borazine, hexaphenyl borazole, hexamethyl borazole, etc. A hexagonal BN sintered body is obtd. by executing the sintering under normal pressure. A dense sintered body having high purity is obtd. since the precursor monomer having a B-N bond causes contraction when it is polymerized at high temp. Obtd. sintered body is used suitably for an electric insulating material, material for a high temp. electric furnace, etc.

Title: Video signal noise reducing circuit
Inventor: KAWAKAMI SHIGERU
IPC: H04N5/21
Filed: 1990-04-18
Abstract: PURPOSE:To reduce the change of the amplitude of a carrier chrominance signal of a video signal by eliminating a chrominance subcarrier component of the video signal from a first output of a distributor by a trap filter whose center frequency is the chrominance subcarrier frequency of the video signal and taking out only a high band component of the video signal by a high-pass filter. CONSTITUTION:The video signal inputted to a distributor 2 is divided into two, and the chrominance subcarrier component of the video signal in the first output 10 is attenuated by a trap filter 3. The high band component of the video signal is taken out by a high-pass filter 4, and the output of the high-pass filter 4 is amplified by an amplifier 5 and is inputted to a limiter 6 and the amplitude is limited to take out noise components other than the chrominance signal of the video signal. Taken-out noise components have the polarity inverted by a polarity inverter 7 and is superposed on a second output 11 of the distributor 2 by a superposing circuit 8, and thus, noise components of the video signal are reduced.

Title: Distortion controller
Inventor: WADA KUNIO
IPC: G05D15/01
Filed: 1981-06-29
Abstract: PURPOSE:To control the distortion of a material testing machine completely and precisely, by load-controlling a distortion set value so that distortion becomes constant or load becomes constant when the load given to a test piece is a prescribed value. CONSTITUTION:A set signal generator 1 generates a signal, which gives the distortion set value of a target value, and outputs this signal to a comparing part 10 with a waveform such as a sine wave, a triangular wave, and a trapezoidal wave required for the test of materials. A deviation (d) is converted to a stop signal through an amplifier 9 and is introduced directly to the generator 1. This generator 1 stops by this stop signal and incrases or reduces a distortion set signal in accordance with the deviation (d) so that the load value detected by a load detector 7 becomes a set load value. In this distortion controller, when the load given to a test piece 4 is changed gradually after stopping the distortion set signal output, the distortion set signal is increased or reduced in accordance with the polarity of the deviation (d) to return the load value to a preliminarily set stop load value.

Title: Heating roller fixing device
Inventor: HASHIDA YOSHINORI
IPC: G03G15/20
Filed: 1978-08-24
Abstract: PURPOSE: To prolong fixing time and make the device small in size, less in consumption energy and low in cost by providing a heating roller, two pressure-contacting rollers and a pressing roller and driving the heating roller at the outside peripheral surface.  
     CONSTITUTION: Pressure-contacting rollers 1, 2 made of heat-resisting rubber and a heating roller 6 by infrared ray lamp or the like are provided afloat from a shaft 8. A pressing roller 12 is held fixed to a pressure revolving shaft 9 and is pressed to the heating roller 6 by the pressure of a spring or the like. When one, e.g., roller 1, of the pressure-contacting rollers is turned counterclockwise, the pressure-contacted roller 6 is turned clockwise and the roller 2 counterclockwise. When the paper to be fixed is put in from the A direction and is sent to the B direction, the paper is fixed under pressure over a long distance between the contact point of the rollers 2 and 6 and the contact point of the rollers 1 and 6 and since the heat losses by the shaft of the heating roller are less, the temperature of the heating roller 6 may be made low hence preheating time short, resulting in decreased consumption energy.

Title: Optical recording method
Inventor: SUZUKI YUKI
IPC: G11B7/246
Filed: 1995-04-26
Abstract: PURPOSE: To obtain a recording method which is capable of forming good microrecording parts in order to realize high-density recording by utilizing phase differences, is capable of having a large recording modulation degree in spite of the slight rate of the change in the film thickness before and after recording and is adequate for short-wavelength recording of a wavelength of 620 to 690nm. CONSTITUTION: This optical recording method comprises making a laser beam of a wavelength of 620 to 690nm incident from a substrate side, changing the film thickness of a recording layer by 10 to 30% by the laser beam condensed onto guide grooves to induce the occurrence of the phase differences of the laser beam arriving at a reflection layer and reading the change in the reflected light quantity by the phase differences. The recording layer of the optical recording medium includes a resin having a glass transition point of >=50 deg.C and a main weight loss initiation temp. higher than 250 deg.C or a resin having the glass transition point of <50 deg.C and the main weight loss initiation temp. of 100 to 250 deg.C and org. dyestuff.

Title: Warning device of automatic exposure control camera
Inventor: MIYASAKA TETSUO
IPC: G03B7/30
Filed: 1983-06-08
Abstract: PURPOSE:To minimize the range of warning display and to reduce the missing of shutter chance by performing the warning display only when a stop-down extent exceeds a set aperture value. CONSTITUTION:The stop-down extent of a stop 2 is calculated on the basis of subject brightness information passed through a lens 1, or the subject information and manual setting information on a shutter speed. This calculated stop- down extent is compared by a comparing circuit A7 with information on a manually set aperture value of a lens barrel. A display circuit LED performs the warning display on the basis of the output of the circuit A7. In this case, an aperture ring is turned to a small-aperture side auto position to perform automatic control over the stop. Therefore, when the stop-down extent is on the open-aperture value side of the set value, the warning display is not performed, so the missing of shutter change is reduced because the re-setting of the aperture value becomes less.
