Patent JP-S62139367-A (JP)
Title: Light emitting diode
Inventor: OTAKA KENGO
IPC: G02B27/30
Filed: 1985-12-13
Abstract: PURPOSE:To increase a coupling efficiency to the device to which light is to be transmitted by forming an incident plane of the lens part which is plastic- molded into a spherical shape forming its radius with an LED chip as the center and forming a projection plane of the lens part into such shape that parallel light fluxes are projected. CONSTITUTION:An enclosure 15 which is plastic-molded is attached to a stem 12 on which an LED chip 11 is mounted. An outside plane (convex part) 15a of a lens part 15-1 of the enclosure 15, namely, the projection plane where a light flux is emitted from the chip 11 is projected from the lens part 15-1 is constructed so that it forms an ellipse with the chip 11 as a focus. Also, an inside plane 15b of the lens part 15-1, namely, the incident plane into the lens part 15-1 of the light flux emitted from the chip 11 is formed into a spherical form with the chip 11 as the center. Consequently, a refraction of the light flux when entering the inside plane 15b of the lens part 15-1 can be prevented and the light fluxes passing through the lens 15-1 become parallel and do not scatter. Accordingly, it can be used as a light source of high efficiency.

Title: Film carrying device
Inventor: SASHITA MINORU
IPC: G03B21/11
Filed: 1988-11-07
Abstract: PURPOSE:To apply the title device to any leader, etc., whatever mirror constitution it has by providing a means for switching the rotating direction of a reel at the time of rewinding a film. CONSTITUTION:When a change-over switch 2 is switched according to the number of the mirrors of the leader in the case of a rewinding action, a normal rotation signal or a reverse rotation signal is transmitted to a control circuit 3 from the change-over switch 2 according to the switching direction and a motor M1 is driven in a direction in accordance with the signal from the change-over switch 2. In such a case, the rotating direction of a supply shaft 1 is an A direction when the microfilm F passes a film path P1 and a B direction when it passes a film path P2. With such a constitution, the film F is rewound without hindrance even if a supply reel 5 is loaded from either direction of a surface and a back surface.

Title: Redundant circuit for semiconductor memory
Inventor: TAKAHASHI YASUNAO
IPC: G11C29/04
Filed: 1989-10-27
Abstract: PURPOSE:To suppress the increase of current consumption caused by short- circuiting between a word line and a bit line by providing a transistor between a precharge activating signal and a GND and further providing a fuse in the precharge activating signal. CONSTITUTION:When a bit line BL1 and a word line WL1 are short-circuited, an NMOS transistor Q2 is turned ON by a precharge signal phi1 and the bit line BL1 is precharged by a precharge power source 1. At such a time, a current flows from a short-circuited part through the word line WL1 and the NMOS transistor Q2 to the GND. However, when a fuse F1 of the defective bit line BL1 is fused, a transistor Q1 for precharge activation is turned OFF by a transistor Q13 and a current path from the precharge power source 1 to the defective bit line is interrupted. Thus, even when the bit line and the word line are short- circuited, the current consumption is not increased.

Title: Powdered leaf of acanthopanax senticosus
Inventor: ABE TOSHIO
IPC: A61K36/25
Filed: 1984-12-29
Abstract: PURPOSE:To obtain the titled powder having excellent storage stability, by drying the collected leaf of EZO-UKOGI (Acanthopanax senticosus) in a preliminarily heated drying chamber at a temperature not to cause the discoloration of the leaf, and pulverizing the dried powder. CONSTITUTION:The leaf of EZO-UKOGI is collected, washed with water, drained, put into a drying chamber heated preliminarily at about 40 deg.C, and dried at 50-70 deg.C, preferably at about 60 deg.C for about 8-12hr to obtain the objective powdered leaf of EZO-UKOGI. Although the leaf of EZO-UKOGI contains large amount of vitamin A, vitamin C, chlorophyll, etc., as well as the drug component contained in the woody part, however, the leaf if liable to be decayed because of its high water-content, and turns to black gradually after collection of turns to brown color and decreases the active component when dried in the sun. The change in the green color and the loss of the drug component can be prevented by drying the leaf according to the above method. Since the product has powdery form having low water-content (about 4.5%), the generation of mildew and mite can be completely prevented.

Title: Thin film magnetic head
Inventor: KATO YOSHIAKI
IPC: G11B5/31
Filed: 1987-11-10
Abstract: PURPOSE:To improve an S/N by embedding an upper layer coil conductor between lower layer coil conductors under a specific condition, and setting the interval of the lower layer coil conductors and that of the upper layer coil conductors at >=7mum and <=15mum. CONSTITUTION:Assuming the interval of the lower layer coil conductor as S, the tile angle of the lower layer coil conductor as theta, the thickness of the coil conductor as (t), and the conductor width of the upper coil conductor after etching as L, the upper layer coil conductor 5 is embedded between the lower layer coil conductors 3 so as to satisfy a condition L-S-2t/tantheta<=20. Thereby, a step quantity can be reduced remarkably, and excessive over-etching in an insulating layer 4 or the etching to the upper layer coil conductor 5 can be prevented from occurring even when an upper magnetic material 7 is removed by the etching. Also, coil length is increased by setting the interval S of the lower layer coil conductors or that of the upper layer coil conductors at >=7mum and <=15mum. In such a way, it is possible to reduce DC resistance and to improve the S/N.

Title: Rectangular wave recovering device
Inventor: KITAGAWA KEIICHI
IPC: H03K5/08
Filed: 1987-11-10
Abstract: PURPOSE:To obtain a waveform not subject to fluctuation of a DC bias as an output waveform by obtaining a reference input signal compared with an input signal so as to obtain the input signal at a charge/discharge circuit as transient response. CONSTITUTION:An input signal is inputted as it is to one input terminal 6 of a comparator 1, a reference input signal converting the input signal into the transient state by a charge/discharge circuit 4 is supplied to other input terminal 7 of the comparator 1 to compare the input signal and the reference input signal, thereby recovering a rectangular wave. Since the input signal and the reference input signal compared by the comparator 1 have the same DC component, even if the DC bias of the input signal varies due to the distance of a transmission line or the like, the change in the relative level between the input signal and the reference input signal is prevented, and the input signal immediately follows the reference input signal even if a discontinuous input signal is inputted, then a rectangular wave stable in waveform is obtained since the signal is inputted.

Title: Optical character reader
Inventor: AKI MASATOSHI
IPC: G06K9/68
Filed: 1991-10-29
Abstract: PURPOSE:To reduce variation of character recognizing time due to comparison order difference and to raise operation efficiency by changing pattern matching order based upon reference pattern for each set character font on the way of reading. CONSTITUTION:A character segmenting control part 3 separates the slip data obtained by a photoelectric conversion part 1 for each character pattern. A pattern matching process part 7 executes pattern matching process using this character pattern as an input pattern and also using a reference pattern as a comparison data so as to output non-coincidence numbers. A character decision control part 6 executes pattern matching by changing the reference patterns until the non-coincidence numbers of reference value is outputted. When the non-coincidence numbers above the reference value is outputted, the character font comparison order in the character decision control part 6 is compared with a current character font. If the order is lower one, priority order is changed and advances to the matching process for the next input pattern.
