Title: Drive control for thermal head
Inventor: MIYASHITA KAZUHISA
IPC: B41J2/36
Filed: 1983-09-30
Abstract: PURPOSE:To enable a high-speed printing without lowering the printing quality by applying a pulse with a uniformly set pulse width to a heat generating body at the position of a dot under a specified condition. CONSTITUTION:The printing pulse Px shall have the pulse width t3 the same when a printing pulse P(x-3) exists at the dot position D(x-3) three dots ahead of the dot position Dx for printing and when a printing pulse P(x-2) exists at the dot position D(x-2) two dots ahead of the Dx. The pulse is applied to each heat generating body with the pulse width t3 in the almost middle (t1<t3>t2) between the pulse width t1 determined when the printing pulse P(x-2) two dots ahead of Dx by a 2-stage control system and the pulse width t2 determined when the printing pulse P(x-3) exists three dots ahead of Dx by 3-stage control system. Thus, though a printing pulse exists two dots ahead of the dot position for printing with respect to the heat generating body 1 and it exists three dots ahead of Dx for the heat generating body 2, both are applied with the pulse width equivalant to application time t3 uniformly thereby enabling the printing with an equalized printing density.

IPC: G02B5/18
Filed: 1985-08-20
Abstract: PURPOSE:To form grooves which have a desired saw-tooth section shape in a substrate and to obtain a blaze grating which has high diffraction grating by beams incident at the same time in such two different directions that a projection on a substrate in at least one direction extends not in parallel to the diffraction grating of a mask on the substrate. CONSTITUTION:A photoresist film 22 is formed on the surface of an SiO2 substrate 21.

IPC: B22D11/18
Filed: 1991-06-26
Abstract: PURPOSE:To provide means for preventing pouring of slag in a tundish into a mold at the time of executing multi-sequential continuous castings. CONSTITUTION:At the time of coming to the end period of molten steel casting in the tundish 1 for the previous heat in the multi-sequential continuous castings, a molten steel surface level signal in the mold 4 and an opening degree signal for a sliding nozzle 2 are inputted into an arithmetic and control unit 13. In there, lowering speed of the molten steel surface level and the opening degree of the sliding nozzle, are obtd. The obtd. values and the preset reference values are compared, and in the case of executing the reference value, the sliding nozzle 2 is closed and the slag is shut-off. The slag in the tundish for the previous heat is not poured into the mold. As the closing operation of the sliding nozzle can be automatically executed, pouring of the slag can be perfectly prevented and quality of the cast slab is improved. Operational trouble, such as breakout, is eliminated.

Abstract: PURPOSE:To make a synchronizing reception the best by varying a synchronizing control signal in a prescribed range so that a synchronizing reception state may be the best, deciding whether the synchronizing reception state is the best state or not when a channel selection is performed for a broadcasting channel and a reception is performed. CONSTITUTION:The DAC value according to a channel for which a station selection is to be performed is read from the memory of a microcomputer MC for control and is outputted to a low-pass filter 4 via an inverter 3. From the filter 4, the tuning voltage signal VT according to the DAC value is supplied to a tuning voltage signal input terminal 5a, and if a tuner unit 5 receives a broadcasting ratio wave, an AFC signal having the sigmoid characteristic is outputted from an AFC signal terminal 5c and a video signal is outputted from a video signal output terminal 5d. If they are outputted, whether the response by a reception synchronization or a synchronizing detection signal from a synchronizing detection part 2 is outputted to an SD input terminal 1d composing a station selection part 1 or not is decided. If the response is not received in the terminal 1d, the DAC value is varied in a lower limit direction.

Title: Displacement detecting device
Inventor: CHICHII MASARU
IPC: G01D5/38
Filed: 1995-06-26
Abstract: PURPOSE: To find the displacement information of a displaced object from the rotation of polarization direction by synthesizing diffracted luminous fluxes of a specific order from a diffraction grating into a linear polarized luminous flux by superposing the luminous fluxes upon another through a polarized light splitting means and splitting the luminous flux into two fluxes through a one-dimensional diffraction grating, and then, respectively detecting the split luminous fluxes by means of photodetecting means through polarizing elements which polarize light in different directions. CONSTITUTION: After the luminous flux from a light source 11 is made incident on a polarized light splitting means 13, the luminous flux is directed to a polarized light splitting surface 14 and divided into a reflected luminous flux 15 and transmitted luminous flux 16. The flux 15 is emitted from a splitter 13 as a luminous flux IA after passing through a prism 17A. The flux 16 is emitted from the splitter 13 as a luminous flux IB after passing through another prism 17B. Then a luminous flux I is formed by superposing the luminous fluxes upon another and converted into linearly polarized light through a 1/4-wave plate 2. The polarized light is split into two luminous fluxes 4a and 4b though a light splitting means 3 and the split fluxes are respectively made incident on polarizing elements 5a and 5b whose polarization directions are shifted from each other by 45 deg..  The quantity of the luminous fluxes transmitted through the elements 5a and 5b and received by means of light receiving elements 6a and 6b varies sinusoidally and the light receiving elements 6a and 6b output two sine-wave signals having a phase difference of 90 deg. between them when a displaced object is displaced.

Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain improved fracture toughness by changing at least one of the distribution density, diameter and length of the whisker to the inward direction of the whisker composite ceramic. SOLUTION: The objective product is a whisker composite ceramic in which the whisker distribution density is changed inward so that it may become 5-50 vol.% in the surface area bearing the toughens and 0-30 vol.% in the middle part bearing the strength. During the process that the ceramic powder and powder as a raw material for dispersed whiskers are mixed, molded and a sintered, the raw whisker material are allowed to react thereby forming whiskers in the ceramic. In this case, the amount of the whiskers formed in the molded product increases, as the initial relative density becomes lower, wile the formation of whiskers are suppressed as the initial relative density becomes higher. Thus, the initial relative density is controlled to 20-60 wt.% to produce the composite ceramic having the objective performance.  The dispersed whisker raw powder is selected form Si3 N4 , SiO2 , C polycarbosilane as a raw material for SiC or Si3 N4 .
