IPC: H01B1/24
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a small-sized PTC(positive temperature coefficient) in which a precise electrode can be obtained and mounting characteristics are excellent. SOLUTION: Metal foils 3 are connected and formed on front and back faces of a substrate formed in a substantially plate-like form with a PTC composition in which conductive particles are dispersed in crystalline high polymer substance. Patterns are staged on the face of the metal foil 3 to form a plurality of insulation paste layers in a striped form, and the metal foil 3 is cut out in a comb-like piece so as to be exposed partially. Insulation paste layers are formed ranging over one insulation paste layer provided on front and back faces on both sides face in a longitudinal direction. The conductive paste layer is formed ranging from the metal foil 3 exposed onto the face of the insulation paste layer on the both sides face to the insulation paste layer on a reverse face.  A plating film layer is formed on the face of the conductive paste layer and a comb-like piece is cut out in a chip-like form to form a PTC element 1. Since the metal foil 3, the insulative paste layer, the conductive paste layer and an electrode 9 of the plating film layer are formed in a film-like manor, the plurality of PTC elements 1 can readily and collectively be formed.

Title: Worm gear device
Inventor: MOCHIZUKI MASANORI
IPC: F16H55/24
Filed: 1990-02-05
Abstract: PURPOSE:To eliminate backlash by meshing the tooth section of each gear member with the tooth of a worm gear in a slip contact condition, and holding a shaft section of each gear member in such a way as to be freely rotated within a definite range of angle and also as to freely advance and/or retreat within a definite range. CONSTITUTION:Tooth section 21 of a plurality of gear members 2 is meshed with the tooth 11 of a worm gear 1 in a slip contact condition. In this case, the shaft sections 22 of the tooth sections 21 are slidably inserted into each hole section 31 of a disc 3 so that each shaft section 22 is so held as to be freely rotated within a definite range of angle and also as to freely advance and/or retreat within a definite range by means of the regulating shaft 39 and the regulating hole 29 of a tilt angle setting means N. In addition, each shaft section 22 is energized toward the worm gear 1 side within a definite range of advancing and/or retreating by means of each compression spring 34 so that backlash between each tooth section 21 and the worm gear 1 is thereby absorbed. This thereby eliminates backlash for the long period of time, and also can make the tooth sections mutually mate smoother.

Title: Frame pulse phase difference detecting system
Inventor: TANAKA HIROTO
IPC: H04J3/00
Filed: 1991-02-20
Abstract: PURPOSE:To simplify the constitution, and also, to correctly detect the maximum phase difference of plural channels. CONSTITUTION:When a frame pulse of a phase difference detection object is detected by an object frame pulse discriminating part 2, whether the frame pulse concerned is a reference frame pulse or not is discriminated by a reference frame pulse deciding part 5, and when it is the reference frame pulse, a dispersion counter 7 starts to count a clock pulse CL. Subsequently, when a detection of all object frame pulses is discriminated in an all object frame pulse detection deciding part 6, whether a counting value N of the dispersion counter 7 is below a set value Ns or not is decided by a comparing part 8, and when it is below, the counting value concerned is outputted as the maximum phase difference between channels. However, when the counting value N becomes above the set value Ns before the frame pulses of all channels are detected, the reference frame pulse is changed by a reference frame pulse setting part 3 and a measurement of a phase difference is repeated.

Title: Vapor growth system
Inventor: KAIDO ATSUSHI
IPC: H01L21/31
Filed: 1990-02-05
Abstract: PURPOSE:To enable exchanging and cleaning of exhaust pipping with high efficiency, by arranging sensors in the manner in which the optical axis connecting a pair of light projecting and light receiving sensors passes the inside of the exhaust piping, and using light transparent material in an adjacent part containing the point of intersection with the optical axis, as the material of the exhaust piping. CONSTITUTION:A light projecting sensor 6 and a light receiving sensor 7 are arranged outside an exhaust pipping 5 in the manner in which the optical axis connecting the sensors 6 and 7 passes the inside of the exhaust piping 5. Reaction product discharged from a processing chamber deposits on the inner wall of the exhaust piping 5 and the inner surface of a quartz window 8. Until the thickness of the deposition film reaches a specified value, the light radiated from the sensor 6 penetrates reaction product 13, and enters the sensor 7. When the deposition of reaction product progresses significantly, the provability that the light radiated from the sensor 6 is reflected or absorbed by the reaction product 13 increases, so that sufficient light does not enter the sensor 6, and an indicator lamp 9 turns off. Thereby effective maintenance of the system is enabled, and operating efficiency can be improved.

Title: Digital information processing device
Inventor: TSUJI YOSHINOBU
IPC: G11B20/10
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To realize a detection protection circuit of a synchronizing pattern by a small-scale and inexpensive composition. SOLUTION: Detection protection of a synchronizing pattern is performed in software based on a synchronous detection algorithm consisting of 'Initial detection mode' in which a synchronizing pattern is drawn in first. 'Inertia drawing-in mode' which is a synchronizing draw-in mode in an inertia draw-in state in which the mode transitions from the initial detection state to an inertia state, or the mode transitions to the inertia state again to a synchronous error from the inertia state, and 'an inertia mode' presenting an inertia state in which the synchronizing pattern is periodically detected.  Normally, the synchronizing detection protecting operation transitions into a stable state in order of 'initial detection mode'→'inertia draw-in mode'→'inertia mode', however, the detection protection of the synchronizing pattern is performed while selectively transitioning each mode as the mode returns like 'inertia mode'→'inertia draw-in mode', etc., according to the detection protecting state. The memory for the synchronizing pattern detection can be eliminated, and the circuit structure can be made small in scale and inexpensive.

Abstract: PURPOSE:To reduce man-hours in test travel by deciding a command stroke by using a numeric table of stroke torque when a vehicle is accelerated or is operated at constant speed. CONSTITUTION:Prior to the automatic travel of a test vehicle, the relation of engine output torque and accel actuator stroke which generates the torque is stored 7 in the numeric table 6 at every test vehicle by using speed, variable speed 3, and engine speed 5 at that time by teaching. When the automatic travel is started, a horse power PS required for the travel of the vehicle is computed 10 based on commanded speed and variable speed designated by the data of automatic travel, and it is decided 11 whether the vehicle should be accelerated or it can be operated at constant speed. When it is decided that the vehicle should be accelerated or is operated at constant speed, a required horse power is converted 12 to the engine output torque T based on the engine speed at that time, and the accel actuator stroke which generates the torque T is computed 13 by using the table 7 of stroke torque. Such stroke is commanded to an accel actuator 2, and an accel pedal 1 is pressed more powerfully, and torque corresponding to a request is generated.
