Title: Plasma display device
Inventor: KAWADA TOYOSHI
IPC: G09G3/293
Filed: 1990-03-30
Abstract: PURPOSE:To obtain the device whose light emission brightness can easily and securely be adjusted by generating a pulse train for generation according to a control signal which controls the frequency of pulse train generation in (n) horizontal periods (n: positive integer). CONSTITUTION:A pulse train generation control circuit 20 outputs the control signal C for controlling the number of pulse trains generated in (n) horizontal periods to a display driving pulse generator 10. Consequently, the generator 10 generates the pulse train for light emission to adjust the brightness. Namely, the control circuit 20 adjusts the brightness by controlling an increase or decrease in the number of pulse trains generated in one horizontal period Hs with the control signal while regarding the horizontal period H of one group of (n) successive trains as one adjustment horizontal period Hs (=nXH), so the brightness is increased by increasing the number of pulse trains (frequency of light emission) and decreased by decreasing the number of pulse trains.

Title: Band pass filter and its manufacture
Inventor: KONISHI YOSHIHIRO
IPC: H01P1/212
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To easily and highly precisely manufacture a band pass filter with less dispersion by providing a layer constituted of a material whose dielectric rate is lower than that of an open end face-side for the shorting end face side of a dielectric block which has an inner conductor and is provided with a through hole. SOLUTION: A high dielectric part 10a is formed by the dielectric material of the high dielectric constant and a low dielectric constant part 10b is formed by time dielectric material having the low dielectric constant and the dielectric block 10 is constituted. Thus, inductance increases and the characteristic impedance of a resonator changes. Thus, a higher harmonic band can be shifted from an odd-fold basic frequency band with simple constitution. Then, the filter can be miniaturized and a simple form can be obtained. Thus, it can be formed with high dimension precision. Then, the dielectric block can be manufactured only by putting the resonator dielectric unit in a shaping mold and filling the resin material of the low dielectric constant, and manufacture dispersion can be suppressed to be small.

Abstract: PURPOSE:To produce a magnetic head having high accuracy and high efficiency by etching away a protective film of a rgion including a pattern for checking a cutting part and polishing position from a substrate formed thereon with magnetic poles, conductive coils and insulating layer prior to cutting of the substrate. CONSTITUTION:The lower protective film 2, the magnetic poles 3-6, the conductive coils 9, 10 and the insulating layer 11 are formed on the substrate 1 and after the upper protective film 8 is formed thereon, the substrate is cut and polished. The protective film 8 of the region including the pattern 13 for checking the cutting part and polishing position is preliminarily removed by etching prior to the cutting of the substrate, then a grinding wheel 12 and the film 8 do not contact with each other in the stage of cutting the substrate and therefore the exertion of the impact and distortion to the protective film is obviated. The high-speed cutting of the substrate is thus made possible and the reduction of area in each working stage is exactly known from the exposed check pattern 13. The control of the gap depth is thus made easy.

Abstract: PURPOSE: To extend an area supported by a base station by sending a 2nd incoming notice including at least a telephone number of a caller terminal and an ID code of the called portable telephone set when no reply comes from the portable telephone set. CONSTITUTION: A base station 10-1 gives up communication with a telephone set 20-2 when no acknowledge of channel link is returned from the portable telephone set 20-2 even with the trial of channel link request for three times. Then the 2nd incoming notice is sent to the telephone set 20-2 and no reply is informed to a telephone terminal 4 via a public network. Since the 2nd incoming call notice is sent with a higher output level than that of a usual channel link request, even the telephone set 20-2 resident at the outside of a radio zone. The telephone set 20-2 receiving the 2nd incoming call notice including the telephone number of the caller telephone set and the ID code of the called portable telephone set confirms whether or not the the ID is coincident with its own ID code.  Thus, the caller information is sent to the telephone set 20-2 resident at the outside of the radio zone.

Title: Steering device for vehicle
Inventor: NISHIZAKI KATSUTOSHI
IPC: B62D6/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To quickly switch to a normal steering mode according to the intention of a driver without being influenced by external disturbances if an emergency situation occur in an automatic steering mode in a vehicular steering device capable of selecting the automatic steering mode and the normal steering mode. SOLUTION: A steering mode is switched between an automatic steering mode for causing an actuator 50 to generate a steering force and a normal steering mode for causing a driver to generate a steering force based on a command signal from a controller. During the automatic steering, a value corresponding to a steering force added other than the steering force generated by the actuator 50 is detected. Then, determination is made as to whether the added steering force is one added by the driver or the outside to a vehicle. If the added steering force is determined to be one added by the driver and a value corresponding to the added steering force exceeds a specified value, the automatic steering mode is switched to the normal steering mode.

Title: Branching device of polarization plane preserving optical fiber type
Inventor: IIZUKA TOSHIO
IPC: G02B6/024
Filed: 1982-05-21
Abstract: PURPOSE:To change optionally a branching ratio, by rotating the fiber axis of the exit end of a polarization plane preserving optical fiber, or rotating an optical activity element to rotate the axis of polarization. CONSTITUTION:Though the light emitted from an incidence-side polarization plane preserving optical fiber 6 is branched by a polarizing beam splitter 7 after reducing to a parallel light through a collimator lens 2a, the light in the (y) (or x) direction orthogonal to the light polarized in the (x) (or y) direction is reflected when the light polarized in the (x) (or y) direction passes through the polarizing beam splitter 7. Consequently, if the fiber axis of the exit end of the polarization plane preserving optical fiber 6 is rotated at an angle theta to change the (x) direction to a direction x' when the light polarized in the (x) direction is propagated in the incidence-side polarization plane preserving optical fiber 6, the intensity of the light incident to an optical fiber 4 is changed; and the angle theta is changed to obtain an optional branching device. The branching ratio can be changed continuously by changing the angle theta continuously.
