Title: Recording current controller
Inventor: INADA HIROSHI
IPC: G11B7/125
Filed: 1986-10-14
Abstract: PURPOSE:To execute an accurate recording to a recording medium by providing a signal output means obtaining a signal in response to the frequency of a recording signal and a recording current control circuit controlling a current flowing to a laser beam source depending on the output of the signal output means. CONSTITUTION:A recording signal is inputted to an LD driving circuit 4 and a frequency level conversion circuit 2, which outputs a level signal in response to the frequency of the recording signal. A recording current control circuit 3 receives the output of the frequency level conversion circuit 2 to control a current flowing to a laser diode 1 proportional to the output of the frequency level conversion circuit 2. The LD driving circuit 4 uses a recording current specified by the recording current control circuit 3 to drive the laser diode 1 according to the recording signal.

Title: Printing tape cartridge
Inventor: FURUYA YOSHIKIYO
IPC: B41J3/36
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent the tip of a printing tape from entering or clogging a cartridge case by a method wherein a back stopping mechanism, which checks the rotation opposite to the delivering direction of the printing tape to a tape core, is provided. SOLUTION: At the middle stage position of the inner peripheral part of a tape core 2, a circular disc part journaled rotatably to the projection 1 of a lower case is formed. On the front and rear sides of this circular disc part, ratchet grooves 2a are planarly formed. Each ratchet groove 2a consists of a planar ratchet, on which sawteeth are formed unidireftionally. Accordingly, the linear engaging part 4a of a back stop spring 4 engages with the ratchet groove 2a, resulting in checking the rotation of a tape core 2 to the direction indicated with the arrow B and, at the same time, allowing its rotation to the direction indicated with the arrow A.  In short, since only the rotation of the tape core 2 to the A direction is allowed by the ratchet structure consisting of the tape core 2 and the back stop spring 4, no pulling-in of the delivering end of a printing tape 3 in a cartridge case 1 occurs.

Title: Thin film transistor and manufacture thereof
Inventor: ITOGA TAKASHI
IPC: G02F1/1368
Filed: 1992-09-10
Abstract: PURPOSE:To obtain a highly reliable TFT wherein there is less leakage between the gate and source electrodes and between the gate and drain electrodes. CONSTITUTION:A gate electrode 4 and anode oxidation film 5 are formed in a trench 2 formed in a substrate 1 in a way that the upper face of the anode oxidation film 5 is flush with the substrate 1. This enables flatly forming a gate insulating film 6 and amorphous Si film 7 thereon without steps. Accordingly, that prevents the gate insulating film 6 from being holed due to the increase of etching rate at steps in the subsequent processes. Thus the leakage from TFTs is prevented.

Title: Antenna booster amplifier
Inventor: TAKAYAMA KAZUO
IPC: H03G3/20
Filed: 1983-12-21
Abstract: PURPOSE:To reduce the suppression of a desired signal level with no deterioration caused to the mutual modulation characteristics, by connecting an input signal application gate of a dual gate FET of an antenna booster amplifier and an AC coupling element for connection between outputs. CONSTITUTION:A dual gate FET21 is used to a variable gain amplifier of an automatic control type which receives a reception input from an antenna. Then the input signal given from a terminal IN is impressed to a gate G1 together with the bias voltage VB via a resistance R1. While AGC voltage VA is impressed to a gate G2. An AC coupling element 4 consisting of a resistance R0 and a capacitor C0 is connected to an area between the G1 of the FET21 and the output of a drain D. The working point of the FET21 moves to a point having good linearity by the voltage VA. However the reduction of the overall gain is limited apparently down to a fixed level owing to an element 4. Thus it is possible to deliver an output with no deterioration of the mutual modulation characteristics and without suppressing the level of a desired signal so much.

Filed: 1986-10-13
Abstract: PURPOSE:To facilitate adjustment of printing density, by providing a gap having a width in the same direction as the direction of a stoke in which a tip part of a leaf spring is attracted, between an attracting part and a support part, and variably regulating the width of the gap to adjust an attraction stroke. CONSTITUTION:A gap 32 having a width in the same direction as the direction of a stroke in which a tip part of a leaf spring 18 is attracted is provided between a yoke member 10 serving as an attracting part and a yoke member 12 surving as a support member. As the width of the gap 32 is reduced, an attraction stroke is reduced, with the result of a weaker impact force and a lower printed density. Conversely, as the width of the gap 32 is enlarged, the attraction stoke is increased, with the result of a greater impact force and a higher printed density. This adjustment can be easily performed by turning a screw 28. In addition, the condition of the adjustment can be checked while performing test printing by driving the leaf spring 18 during an operation, and accurate adjustment can be speedily performed.

Abstract: PURPOSE:To improve the visual angle characteristic of a twisted nematic liquid crystal display device STN-LCD by forming a birefringent film of at least one uniaxially drawn film made of a light-transmissive polymer which has a positive and a negative specific birefringence value.

Title: Fuel cell
Inventor: SEKI TOSHIAKI
IPC: H01M8/02
Filed: 1986-10-15
Abstract: PURPOSE:To make a cooling plate thin and lightweight by embedding cooling pipes in highly flexible expanded graphite and sandwiching between high anticorrosion glassy carbon plates. CONSTITUTION:Cooling pipes 42 are embedded under compression in expanded graphite 50 obtained by treating flake graphite having high crystallinity with acid, then heating at high temperature, and sandwiching between high anticorrosion glassy carbon plates 51. The surrounding of the expanding graphite 50 is impregnated with resol type phenol resin or fluorine resin adhesive paint which are resistant to phosphoric acid to increase the shape stability. Since the compressed body of the expanded graphite is highly flexible, a cooling plate can be thin to the thickness near the diameter of the cooling pipe 42, and the maximum thickness of 0.6mm is enough for the glassy carbon plate 51. In this cooling plate, when the cooling pipe 42 having a diameter of 3mm is used, the thickness of the cooling plate becomes about 5mm. This thickness is almost half that of a cooling plate using norman graphite plate.
