Abstract: PURPOSE:To prevent the denaturation of mercury thereby to improve the accuracy by connecting an end part at the side of a cathode of a semiconductor circuit network showing a larger voltage decrease to the side of mercury and the other part to a power source, and controlling a current flowing into a liquid tank via the mercury to be slightly smaller than a current flowing out of the liquid tank. CONSTITUTION:Diodes D1, D2 are connected in series, and a diode D3 is provided in a reverse direction in parallel to the diodes D1, D2, thereby constituting a semiconductor circuit network 17. The circuit network 17 is placed between a three-phase power source E and the phase of a mercury 5 (second phase T2). A part of a larger voltage drop at the side of the cathode is set as a mounting side and connected to the side of the mercury 5. The voltage drop when a current passes through the diodes D1, D2 in the circuit network is always larger by the amount of one diode than that when a current passes through the diode D3. Therefore, a current flowing into a liquid tank via the mercury 5 can be made smaller than a current flowing out of the liquid tank at all times, so that the friction torque of the mercury can be maintained in the initial state (as a fresh product).

Title: Method for detecting etched depth for dry etching apparatus
Inventor: YAMAMOTO HITOSHI
IPC: H01L21/302
Filed: 1984-11-30
Abstract: PURPOSE:To realize an uninterrupted monitoring of the quantities etched in an etching process by a method wherein the surface exposed to etching is irradiated with a laser beam and the number of coherent waves in the reflection is counted for the determination of the etched depth. CONSTITUTION:A laser beam 110 originating in a laser source 11 is applied through a window 15 vertically to a surface 166 to be etched, producing a reflection composed of a reflection 111 from the surface 166 and some coherent waves. The coherent waves exist as the result of the interference between the reflection 111 and another reflection 112 back from the surface of an SiO2 layer 162 after travelling through a layer 163 and the number of the waves is dependent on the distance td between the two surfaces. The intensity of the reflection is detected by a photoelectric detector 14, and the value is compared with a threshold level 324 that is the reference level signal 24 of the laser beam 110. A rectangular signal similar to a waveform 323 is generated by a level judging unit 23 with the threshold level 324 serving as a trigger level. The minus slope (trailing edge) is formed into a trigger signal (waveform 325) for the activation of a counter 25, which gives the etched quantity (depth).

Title: Endless belt, its manufacturing device and manufacture thereof
Inventor: MATSUO MINORU
IPC: B29K79/00
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent generation of dislocation with an easy structure. SOLUTION: An endless belt 1 is tensed over at least two rollers 2 whose both ends are tapered, for example, and both ends of the belt 1 are heated by a heater 4 to be deformed so that the circumference of both ends of the belt 1 may be shorter than the circumference of any other portion. When the endless belt 1 is used in a belt device, the shorter portion in the circumference of both ends becomes a stopper when the belt 1 is dislocated to serve as a side stopper of the belt 1. The belt itself prevents generation of dislocation, thus it is possible to prevent the dislocation in driving the belt with an easy structure as compared with a case where a side stopping member such as a tape is attached.

Title: Information recording device for writable disk
Inventor: TAKAHASHI SHINYA
IPC: G11B7/00
Filed: 1991-09-30
Abstract: PURPOSE:To prevent overwriting by inhibiting the track jumping to the inner peripheral side of a disk by means of an inhibiting means when actuators supported by means of a carriage through an elastic body start to make the tracking jumping at the time of recording information, on a writable disk. CONSTITUTION:When a change-over switch 112 is closed at the time of recording operations, an amplifier 109 is made to add an offset current IOFS from a constant-current source 111. Since a main offset current IOFS is supplied to a carriage motor 110 through the amplifier 109 even when a deflected amount signal ISFT from a carriage equalizer 108 is '0', the carriage 105 is moved to the outer periphery side relatively to actuators 102. As a result, the optical axis of optical parts 103 is displaced to the inner peripheral side of an MD 114 by a prescribed offset length OFS against the neutral position of the carriage 105. In other words, the actuators 102 are displaced by the offset length OFS unless a tracking error signal TE is given to the actuators 102 and the actuators 102 are set to standby states.

Title: Automatic speed change control system
Inventor: YAMAMOTO MITSUO
IPC: B60W10/10
Filed: 1984-11-29
Abstract: PURPOSE:To ensure the safety of speed change operation by restricting the speed change gear to the second or third speed when a vehicle speed detecting signal becomes not obtainable, and restricting the speed gear when engine revolution is less than a prescribed value. CONSTITUTION:When the output of a vehicle speed sensor has vanished during high speed traveling, a breaking flag is raised, and the vehicle comes into the second or the third speed traveling. When engine revolution once decreases to be less than a threshold value, the vehicle speed of the third, second or first speed is selected in accordance with the shift lever position of D range, 2 range or L range, and, after that, the state in which a breaking flag is raised is maintained until the output of the vehicle speed sensor is restored, and conse quently the third, second or first speed is primarily determined by shifting the shift lever to select the D range, 2 range or L range. Accordingly, when the output of vehicle speed detecting means is cut, the second or third speed is determined, and, when the vehicle speed becomes less than a threshold value, the speed change operation can be shifted to manual shift.

IPC: G06K9/00
Filed: 1992-09-22
Abstract: PURPOSE:To provide an optical character reader in which correcting work by an operator is reduced, and the recognition rate of a character is improved. CONSTITUTION:A recognizing part 6 outputs a character candidate string by using a recognition dictionary part 5. A knowledge processing part 8 collates the combination of character candidates with a word dictionary, and outputs a word candidate string in the order of the highness of the marks obtained.

Even in the case that the marks obtained of the first rank and the second rank among the word candidate string become equal to each other, they are not rejected, but the character candidate is outputted again by collating the character image of a low correct solution rate with the character pattern of a narrow range stored in the recognition dictionary part 5 as being classified in this way, and therefore, the character candidate of the high correct solution rate can be outputted.

Filed: 1988-10-06
Abstract: PURPOSE:To obtain a metal magnetic powder whose coercive force is high at 800 oersteds or higher boy decomposing a carbonyl compound whose main metal is cobalt. CONSTITUTION:This magnetic powder is obtained by decomposing a metal carbonyl compound whose main metal is cobalt, i.e., by pyrolyzing the compound in a gas phase.
