Title: Position detecting device
Inventor: UCHIDA GEN
IPC: G03F9/02
Filed: 1992-10-20
Abstract: PURPOSE:To provide the position detecting device which can accurately detect the position and tilt of a partial area on a surface to be inspected in the optical axis direction of an objective optical system and can be arranged compactly in a limited space. CONSTITUTION:Projection lights from light sources 11a1 and 11a2 are passed through a condenser lens 12 and a projection slit 13 and are bent by a mirror 14, and further passed through an optical transmission side objective 15 and split by a half-prism 16. The split lights form images of the slit 13 at mutually different detection positions a1-a4 on the surface to be inspected. Reflected lights from respective detection positions are passed through a mirror 14a and a photodetection side objective 15 and photodetected by photodetecting elements 17a1-17a4.

Title: Filling time determining method of transmission clutch
Inventor: HILLMAN JONATHAN R
IPC: F16H61/08
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To secure smooth shift operation by detecting an engine speed within a specified range, reading stepwise increment pulse time value corresponding to the detected speed, and obtaining the adjusted pulse time value using the read stepwise pulse time value and a specified nominal pulse time value. SOLUTION: An electronic control module 26 controls the operation of a control valve 22 in response to input signals input from a shift lever 28 and an engine speed sensor 30. At this time, in the electronic control module 26, a stepwise pulse time value corresponding to an engine speed signal received from the speed sensor 30 is obtained using a map of stepwise increment pulse time value related to a specified range of an intermediate engine speed, which is recorded in a memory device 36. Secondly, an adjusted pulse time is obtained using the read value of the stepwise increment pulse time and nominal pulse time value to control a control valve 22. Thus, the filling time of a transmission clutch is optimized to accomplish smooth shifting.

Title: Thermal head
Inventor: FUJII MITSURU
IPC: B41J2/345
Filed: 1987-12-02
Abstract: PURPOSE:To obtain a larger number of driving IC chips, by making the mount position interval of the driving IC chips shorter than the position interval of the heat generators corresponding to the respective driving IC chips. CONSTITUTION:For example, in a thermal head wherein the total number of heat generators 2 are 672 and the density of heat generators is 8 pieces/mm and the total length of the heat generators is 84mm, for example, 11 driving IC chips 5 each capable of driving 64 heat generators are mounted. Therefore, the mount position interval of the driving IC chips 5 becomes 7.5mm and becomes shorter than the position interval of 8mm of the heat generators 2 corresponding to the driving IC chips 5. Therefore, even when the length of a substrate 1 is 90mm for example, the space of a common electrode 3 can be sufficiently obtained. Therefore, three chips are available from a B4-size substrate having a length of 270mm. By this method, a large number of chips can be obtained without enlarging the size of the substrate and manufacturing cost can be reduced.

By the height of matching rate, it can be judged automatically whether the sticking condition of a conductive film 7 is good or bad.
Patent JP-H03166822-A (JP)
Title: Semiconductor integrated circuit device
Inventor: SAKAMOTO MASARU
IPC: H01L27/10
Filed: 1989-11-27
Abstract: PURPOSE:To prevent a through current from being generated by providing a buffer circuit for a reference voltage deviated from the reference potential of emitter coupled logic(ECL) level on the input part of a circuit which converts the signal of (ECL) level into a CMOS level signal. CONSTITUTION:An address buffer ADB generates the ECL level signal which has a -1.3V reference voltage, a -0.9V H level, and a -1.7V L level. The amplifier LVA for level conversion which is provided on the input part of the level converting circuit LVC has an about -1.5V reference voltage VRF between a reference voltage VBB and the L level. Therefore, when an external address signal is set to an intermediate level, the output of a wired OR WOR circuit also has an intermediate potential like the voltage VBB. An amplifier LVA, however, has the voltage VRF deviating to the L-level side, so the intermediate level like the voltage VBB is regarded as an H level to generate the output signal of level corresponding to the nonselection state of a word line. Consequently, no through current flows through the output-side MOSFETs Q2 and Q4 of the circuit LVC.

Abstract: PURPOSE:To improve a thyristor of this design in cutoff strength as holding down an ON-voltage by a method wherein two or more separate gate turn-off thyristor (GTO) element sections are formed on the same semiconductor substrate to control a load current at turn-ON or turn-OFF. CONSTITUTION:Two or more strip-like n-type cathode emitter layers 2 are formed in a radial manner on the surface of a circular semiconductor substrate, a p-type cathode base layer 3 is provided as being exposed surrounding the layers 2, and the layer 3 is divided into an inner and an outer part through a groove 7 to form GTO element sections (a) and (b). A low resistivity semiconductor layer 4, which serves as a buried gate inside the layer 3, is so arranged in distribution as to make the gate drawing resistance of the element section a lower than that of the section (b). Therefore, a load current is controlled so as to flow through the element section (b) whose On-voltage is low in an On-state and to flow through the element section a whose cutoff strength is large at turn-off, whereby a thyristor of this design can be improved in cutoff strength restraining an ON-voltage.

Title: High reliability self-exciting power converter
Inventor: SHIMOMURA TETSUYA
IPC: H02M1/06
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To improve the reliability by the multiplification while pulses having small widths are suppressed by a method wherein minimum pulse width regulators are provided in three systems to generate signals from which pulses having small widths are eliminated and a majority operation is performed by a majority decision circuit. SOLUTION: Small width on-pulses which cause the device breakdown of a GTO are eliminated by a minimum pulse width regulator 140-1 from a pulse signal A4 which is outputted from a pulse generator 130-1 and a pulse signal A5 is outputted. A timing regulator 150-1 outputs an ignition pulse signal A6 whose on-timing and off-timing are regulated for the respective GTO's so as to turn on and turn off the GTO's connected to one arm simultaneously. The ignition pulse signals A6, B6 and C6 which are outputted from the timing regulators 150-1, 150-2 and 150-3 are inputted to a majority circuit-2 160 in which the majority operation is performed to output an ignition pulse signal 180. As a result, the reliability can be improved while the small width on-pulses are suppressed.

Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To join works more efficiently and in a more full-automatic manner than conventionally and make effective use of a material to save a material cost by deciding a position where the longitudinal end face parts of specific works conveyed one after another come into contact with each other at a specified spot and joining the contact parts.

The conveyance device is equipped with a chain conveyor with a conveying truck having a dog which protrudes from a groove part 32a provided on a conveying table 32 along a conveyance path for the work W. When the longitudinal front end face part of a work W conveyed immediately following the preceding work W conveyed comes into contact with the longitudinal rear end face part of the preceding work W, the dog receives pressure to cause the chain conveyor to stop and thus the contact position is determined. Next the contact parts of the two works W whose positions are determined are joined by a nail driving device 4. Thus the joining work is automated and at the same time, the end materials are used in an effective manner to save a material cost.

After spraying resin, the lamination is performed to be for example a surface material / backing material / core layer material / backing material / rear surface material, and then it may be set within a mold having a desired configuration, thereby obtaining a compound molded plate by the press. The molding temperature is usually at 50 - 80 deg.C, and the time required for the press is usually for 2 - 5 minutes, and preferably, the pressing pressure may be of the type which can tolerate the foaming pressure of the resin. Thus, an article having a free curved surface can be molded by the use of a mold, and by an internal die press mold upon pressing it.
