Abstract: PURPOSE:To scan the picture of an original always in a direction rectangular to the subscanning direction, i.e. the horizontal direction, and to read out a ruled line or a straight line finely by inclining an one-dimensional image sensor in accordance with a subscanning speed. CONSTITUTION:The turning speed of a servo motor, i.e. the subscanning speed, is detected by a speed detector 16, its output is converted into a digital signal by an A/D converted 19 and the digital signal is inputted to a control device 20. The control device 20 calculates the input signaland main scanning speed information outputted from a main scanning speed selecting switch 21 and sends an output pulse string corresponding to the calculated value to a pulse motor driving device 22 to drive a pulse motor 5 and control the inclination of a base. Consequently, the image sensor 1 is inclined at an optimum angle and the picture of the original can be scanned always horizontally. Thus, a main scanning direction vector (a scanning distance per unit time) C becomes the resultant vector of the subscanning direction B and the scanning direction A of the image sensor and the resultant vector C is rectangular to the subscanning direction B.

Title: Composition for formation of positive metal oxide thin film pattern and forming method of positive metal oxide thin film pattern
Inventor: SOYAMA NOBUYUKI
IPC: C23F4/04
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To form a positive metal oxide thin film pattern by a solgel method. SOLUTION: This compsn. for formation of a positive metal oxide thin film pattern contains a metal alkoxide and a compd. which generates an etching assistant by irradiation of light. The compsn. is applied on a substrate and irradiated with light so that the difference in the solubility between the irradiated part and the non-irradiated part due to the photolytic reaction in the irradiated part is used for patterning. The metal alkoxide reacts with the etching assistant produced by irradiation of light and changed to be soluble with a solvent. In the irradiated part, the metal alkoxide becomes soluble with a solvent, while in the non-irradiated part, a hydrolyzable metal alkoxide is hydrolyzed with the water content in air to produce a metal hydroxide which is insoluble with the solvent.  By developing the film with a solvent after irradiation of light, only the irradiated part is dissolved and removed, while the non- irraditated part remains to form a positive metal oxide thin film pattern.

Title: Mounting method for electronic component
Inventor: TOMIFUJI TAKAKO
IPC: H05K13/08
Filed: 1991-08-06
Abstract: PURPOSE:To judge propriety of replacing a suction nozzle according to a unified criterion by one mounting error by a method having the steps of judging whether a length and a horizontal position of a holder fall within set ranges or not if an electronic component mounting error occurs, and requesting replacement of the holder in the case of not. CONSTITUTION:If a mounting error occurs, a controller of an electronic component mounting machine measures a length of a suction nozzle of mounting means 3 by a component height detector 1, and compares it with a set value (h). If a malfunction is recognized, further a component position detector 2 compares a component suction position of the nozzle with a set range (p) and judges presence or absence of a malfunction. If both has malfunctions, replacement of the nozzle is informed to a machine operator. Thus, when a first mounting error occurs, the machine can judge whether the nozzle is required to be replaced or not, and eliminate an inefficient mounting operation.

Patent JP-S6088466-A (JP)
Title: Semiconductor device
Inventor: KOIKE RIYOUICHI
IPC: H01L29/73
Filed: 1983-10-21
Abstract: PURPOSE:To enable to impress an arbitrary base input voltage in the range of thicknesses whereby the tunnel phenomenon of an insulation layer occurs by a method wherein a tunnel insulation layer is used in place of the conventional P-N junction. CONSTITUTION:If the insulation layer 21 is thin to the degree that tunnel current flows between a base layer 15 and an emitter electrode 12 at the given potential, carriers due to the tunnel current move from the emitter electrode to the base layer. Here, further giving a potential in reverse bias between a collector layer 13 and the base layer causes the carriers to be absorbed to the collector layer and to reach it by the electric field of a depletion layer between the collector layer and the base layer. Now, if the reverse bias potential between the collector and base layers is high enough, the electric field of the depletion layer increases, almost all of the carriers moved to the base layer by the tunnel current reach the collector layer and then come into the saturated state. As the base layer-emitter electrode voltage increases, the number of moving carriers because of the increase of the tunnel current; accordingly the saturated current increases.

Title: Radio video signal processor
Inventor: SHIBA TAKASHI
IPC: H04B1/707
Filed: 1993-08-09
Abstract: PURPOSE:To separate an image pickup part and a signal recording part and to miniaturize the image pickup part by using a spread spectrum communication system as the communication means of video signals between the image pickup part and the signal recording part. CONSTITUTION:The video signals inputted from an image pickup device are converted to digital signals (14MHz) and then directly spread by being mixed with the output of an PN signal generator 1. A center frequency is up-converted to 3.6GHz and signals are amplified by an amplifier further and outputted from an antenna. When spectrums are spread and transmission is performed in such a manner, since the signals are at a small level in terms of execution, other equipments are not interfered. In the signal recording part, the signals inputted from the antenna are amplified, passed through a SAW matched filter and thus, converted to the impulsive correlation of 14MHz. In a signal recording element, the digital signals are directly recorded or recorded after they are tentatively returned to analog signals.
