IPC: G11B7/00
Filed: 1991-02-28
Abstract: PURPOSE:To improve a recording capacity in a recording medium by converting a binary signal string into the multi-value pit level, changing a pit interval and recording the information after forming a local pit in the medium in accordance with the conversion signal. CONSTITUTION:A modulation circuit 41 divides the content of the information into the signal level and the information on the interval between pits to the information expressed by the binary signal string. The signal level is converted into multi-value pit level by the modulation signal and the space between pits is sequentially set by the modulation signal. In accordance with the conversion signal, the local pit is formed on a recording medium 1 and the information is recorded. A modulation circuit 42 returns the multi-valued signal from the recording medium 1 to the binary signal string. Namely, the binary signal string is sythesized by the pit level detected in the pit level detection part within the modulation circuit and the pit interval detected in the pit interval detection part.

Title: Method for working rare earth group silicate monocrystal
Inventor: KURATA YASUSHI
IPC: B28D5/00
Filed: 1994-03-30
Abstract: PURPOSE:To obtain the smooth side surface without crack and peeling by performing the cylindrical grinding in the condition that the axial direction of a column is set in the direction within a specified range of the angle of inclination from the c-axis. CONSTITUTION:In the case of working rare earth group silicate monocrystal into a columnar shape, a direction within the range of angle of inclination from the c-axis ([001] axis) at 0-65 degree is selected as the axial direction of the column, and the cylindrical grinding is performed, and the generation of crack and peeling of the side surface can be thereby securely prevented. In the case of performing the mirror polishing to the bottom surface of the column, since the cleavage plane ((100)side) crack is easy to be generated at the time of working at a small angle formed by the bottom surface and the (001)-17 side, axial direction of the column is desirably set in the direction at 15 or more of the angle of inclination from the [001] axis. In the relation between the cleavage plane ((100)side) and the column, it is the best to set the axial direction of the column in parallel with the (100) side from a view of the strength to the mechanical impact from outside of the columnar sample after the working.

Filed: 1981-04-21
Abstract: PURPOSE:To manage the axial length, by providing three thickness slip oscillators with different electrical axis directions in a quartz wafer, measuring the resonance frequency of the three oscillators and performing etching so that the ratio of frequency differences can be made constant. CONSTITUTION:Three monitor quartz oscillators with different widths W of a turning fork arm are provided in one wafer. Frequencies of monitor quartz oscillators 14, 15 and 16 are set to f1, f2 and f3 and the ratio of (F2-F1) to (f3-f1) is obtained. (W1/W2)<2>-1/(W1/W3)<2>-1 is obtained and the ratio of the two frequency differences is independent of on the thickness of the oscillators, but only dependent on the width W.

IPC: E21F1/00
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of the number of driven ventilators due to suddenly increasing concentration of contamination in a tunnel. SOLUTION: A measurement for an contamination sensor 5 is compared with a set value for high concentration judgement to monitor and detect whether the concentration of contamination in a tunnel 1 exceeds or not a set upper limit concentration, for judging whether the concentration of contamination in the tunnel 1 is changed by a fixed value or more and increased or not from the change amount of the measurement for the contamination sensor 5 when a high contamination condition such that the concentration of contamination in the tunnel 1 exceeds the upper limit concentration is detected and for judging whether a traffic density in the tunnel 1 is an upper limit density or less or not, based on the maximum density for a fixed time period immediately therebefore, from the number of measured vehicles 4 running in the tunnel 1.  When a high contamination condition such that the concentration of contamination in the tunnel 1 is increased to be a fixed value or more take places, if the traffic density in the tunnel 1 is the upper limit density or less, the measurement for the contamination sensor 5 is invalidated to prohibit the increase and change of the number of driven ventilators 2.

Title: Detecting structure for guide roller abrasion of wire saw
Inventor: MIZUNO YASUO
IPC: B24B27/06
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To detect easily surely an abrasion limit of a guide roller. SOLUTION: Air is supplied to an air passage 74A formed inside a guide roller from a compresser to keep an inside of the air passage 74A at a specific pressure. The air passage 74A, when a guide groove reaches an abrasion limit, is so formed as to be interconnected to the abraded guide groove 72A. Therefore, when the guide groove 72A is abraded to the abbrasion limit to be interconnected to the air passage 74A, air is leaked from the interconnected part to reduce air pressure in the air passage. By detecting drop of the air pressure in the air passage 74A with a pressure sensor 94, the guide groove 72A of the guide roller is detected to have reached the abrasion limit.

Title: Ultrasonic wave type doppler flowmeter
Inventor: SAITOU KOUJI
IPC: G01F1/66
Filed: 1982-04-14
Abstract: PURPOSE:To make it possible to perform the stable measurement and to measure the flow rate accurately even though the acoustic coupling between a detector and a pipe wall is degraded without silencing beats, by controlling the gain of an amplifier so that the DC component of the output of the detector is kept constant. CONSTITUTION:The gain control of a variable gain type frequency amplifier 18 is performed by a current (or voltage). An automatic gain control circuit 19 mainly comprises a Miller integrating circuit, generates a reference voltage for comparing the DC component of the output of a detector 10, and operates as a differential Miller integrating circuit. When the acoustic coupling of the detector and the pipe wall is insufficient, the DC component of the output of the detector 10 is lower than the reference voltage. Therefore, the automatic gain control circuit 19 is operated so that the DC component becomes equal to the reference voltage, and the gain of the variable gain type high frequency amplifier 18 is increased. When said acoustic coupling is fluctuated owing to the external cause, said operation is repeated and the DC component of the output of the detector 10 is kept constant.
