Title: Prober mechanism for inspecting pattern wiring
Inventor: YAMAHA TSUNEO
IPC: G01R1/06
Filed: 1990-06-28
Abstract: PURPOSE:To enable measurement by a 4 termination method for a fine interval wiring by moving four probe pins with a Y movement of a carrier, an X movement of two moving rods and a Y movement of four moving elements to make tips thereof contact a pattern wiring. CONSTITUTION:A ceramic substrate 4 is placed on a carrier 1 and probe pins 91-94 are moved to positions of two pattern wirings to be measured with a Y movement of the carrier 1, an X movement of moving rods 61 and 62 and a Y movement of moving elements 81-84 and stopped. Then, as the carrier 1 rises, the tips of the probe pins 91-94 contact the two pattern wirings. This enables measurement of a resistance by a 4 terminal method.

Title: Measuring device for loss wavelength characteristic of optical fiber
Inventor: TOKUDA MASAMITSU
IPC: G01N21/35
Filed: 1981-10-26
Abstract: PURPOSE:To obtain a measuring device for loss wavelength characteristics having a wide wavelength range and a wide dynamic range by using a light source utilizing the nonlinear optical effect of Raman scattering, 4-photon mixing, etc. that arise when strong light is propagated in an optical fiber. CONSTITUTION:Since pulse oscillation can increase power more largely, the use of a pulse light source as a light source 1 is prevail. As an optical fiber 2 for excitation, a single mode optical fiber can increase light density and therefore 4-photon mixing is produced other than Raman scattering, and the light emission spectra are flat with respect to wavelength. In the case of a multimode optical fiber, many crests are generated in light emission spectra; therefore said fiber is suited for the case when it is desired to obtain strong light with specific wavelength. Light of a wide wavelength range is obtained simply by connecting the fiber 2 to the light source 1, and since the light is stronger by several digits than that of a halogen lamp, the loss wavelength characteristics in a repeater section are measured easily.

Title: Push-button tuner
Inventor: OOHASHI TAMAKI
IPC: H03J5/08
Filed: 1983-09-19
Abstract: PURPOSE:To improve the accuracy of channel selection by dividing an operating into plural parts and fitting each divided operating plate to a support frame freely toward forward and reverse directions respectively. CONSTITUTION:The divided operating plates 45a, 45b are supported to be moved freely forward/backward to a ceiling plate 8d of a support frame 8 via the coupling between a long hole 46a and a pin 47a and between a long hole 46b and a pin 47b respectively. Furthermore, variable tuning parts 48a, 48b are provided corresponding to the operating plates 45a, 45b respectively. Through the constitution as stated above, since the lengthwise size of the operating plate is decreased, even if the channel selection collor of a channel selection member is butted to a position of both side ends of the operating plate, the possibility of the operating plate tilted on a horizontal plane is precluded by the butted forced, the smooth slidable movement of the operating plate is attained and also generation of a channel selection is prevented.

IPC: H01L41/18
Filed: 1980-12-03
Abstract: PURPOSE: To enhance the piezoelectric characteristics of a sintered body by growing the C faces of tetragonal system PbTiO 3  crystals and orienting the resulting platelike crystal grains.  
     CONSTITUTION: For example, potassium titanate fiber is treated with acid to obtain TiO 2 .nH 2 O. This compound is heat treated, and the resulting powder composed of TiO 2  grains extended in the direction of the (a) axis is mixed with lead oxide powder and calcined by heating to obtain platelike PbTiO 3  having practically grown C face. The PbTiO 3  grains are well mixed with a small amount of a binder or the like and molded so that the plate surfaces of the grains are oriented parallel to each other. The molding is then sintered to obtain a sintered body with superior piezoelectric characteristics.

Filed: 1982-09-30
Abstract: PURPOSE:To provide possibility of canceling a recorded sheet at all times by allowing a defoliating member to have pressure contact with a paper feed member by means of insertion of a cassette and slide of a follower along the cam surface of a working member and by stabilizing the defoliating member when the follower comes to the locational surface. CONSTITUTION:When a cassette 2 for recoring sheets is inserted in a paper feed table 1, a working member 13 is pushed forward in front of the cassette 2, and a follower 16 slides along a slope 17a provided on the working member 13 to allow the defoliating member 10 to have pressure contact with the surface of a belt 5. When thereafter the follower 16 comes in coincedence with the locational surface 17b of the cam surface 17, the contact pressure of the defoliating member 10 is held constant regardless of changing position for insertion of the cassette 2. If now the cassette 2 is removed from the paper feed table 1 the defoliating member 10 comes off from the a sheet feeding member 5, so that the record sheet being pinched by the defoliating member 10 and this sheet feeding member 5 is taken out while being placed on the cassette 2, and now there is not risk of leaving any sheets in the takeout process.

Filed: 1979-12-29
Abstract: PURPOSE: To maintain field intensity at a sufficiently large value despite the increase in dust resistance by using a helical electrode for at least one of discharge electrodes and generating a pulse voltage of 1nsW10ms pulse widths from a pulse voltage excitation power source.  
     CONSTITUTION: DC high voltage is applied at all times between discharge electrodes 7 and dust collecting electrodes 6 by a DC power source 11, whereby a main electric field is formed. If, on the other hand, the pulse voltage of 1nsW10ms pulse width is applied between the helical electrodes 7a and 7b, pulselike corona discharge is generated, and cylindrical plasma is generated around the discharge electrodes 7. The negative ions generated by these are drawn out by the main electric field and are emitted toward the dust collecting electrodes 6 which are of positive polarity. In this process, the particles in the main electric field are impinged and charged by the ions, and stick on the dust collecting electrodes 6.

Title: Numerical controller
Inventor: HANAKI YOSHIMARO
IPC: G05B19/418
Filed: 1990-06-29
Abstract: PURPOSE:To continue the operation of input/output (I/O) controllers other than a faulty I/O controller to prevent the reduction of the operating ratio of a control object by by-passing the faulty I/O controller to communicate data in the case of the occurrence of trouble in one or plural I/O controllers. CONSTITUTION:If trouble occurs in a communication part 7 of an I/O control unit (for example, 3b), this unit 3b sends an error detection command. A control main body part 1 (master station) outputs a communication line switching signal when receiving the error detection command, and a communication line switching part 10c receives this signal and disconnects the I/O control unit 3b from a a communication network to by-pass this unit. A CPU 5 of the control main body part 1 substitutes input data of the I/O control unit 3b with data preliminarily held in an operation data holding part 11 and continues to control the other I/O control objects 4a and 4c. Thus, functions except in the trouble position are continuously operated though trouble occurs in the communication network.

Abstract: PURPOSE:To make it possible to form simultaneously a prepared hole and a finished hole and to enable a highly precise finished hole to be formed, by providing finishing cutting blades extending a direction opposite to the spiral direction, and marginal sections in lands which have been formed spirally along the axis of a drill. CONSTITUTION:When the forward end of a drill 10 making into contact with a workpiece is displaced in the direction B along the axis 18, the front edge parts of base sections 14 start to cut the workpiece so that cutting blades 24a through 24c for forming prepared holes cut the workpiece. Then, finishing cutting blades 30a through 30c make contact with the inner peripheral surface of the prepared hole to start finishing work so that the cutting blades 30a through 30c which project in the outer peripheral direction of the drill 10 further than the cutting blades 24a through 24c by  L, cut the inner peripheral wall of the prepared hole to form a hole part. Then, marginal sections 34a through 34c adjacent to the cutting blandes 30a through 30c slide along the inner peripheral wall of the hole part so that varnish finish is made on the inner peripheral wall. Since the varnish finish may be effectively made, thereby it is possible to form an extremely precise hole.
