Title: Character modifying circuit
Inventor: AKEGAMIYAMA YUKIO
IPC: G09G5/24
Filed: 1987-12-29
Abstract: PURPOSE:To coincide a character completely with an underline corresponding to the character without using any timing adjusting circuit by ORing an underline signal with a data load signal and supplying the result to the load terminal of a P/S converting circuit. CONSTITUTION:When an OR circuit 10 which ORs the data load signal and underline signal outputs the data load signal, the P/S converting circuit 11 inputs character data inputted to its parallel terminal and converts it into a serial signal, which is supplied to a CRT to display a character. When the underline signal is outputted, on the other hand, the P/S converting circuit 11 inputs a '1' signal inputted to its serial terminal and outputs it to display an underline on the CRT. Consequently, there is not any circuit which delays a signal on the output side of the P/S converting circuit 11, so a position shift between the character and underline due to out-of-synchronism is precluded completely.

Title: Semiconductor device
Inventor: SUZUKI HIROSHI
IPC: H01L23/02
Filed: 1991-12-19
Abstract: PURPOSE:To prevent a short-circuit between leads connected to a semiconductor chip from being caused by a solder by a method wherein a cap is provided with a solder trap formed in such a way as to fall in the inner peripheral part of the surface of the chip in a step form. CONSTITUTION:A cap 21, which is formed into a frame form and has an opening part in its center, is constituted into a structure, wherein it is provided with a solder trap 21b formed in such a way as to fall in the peripheral part on the inner side of the surface of the chip 21 in a step form. Accordingly, when a second solder 16 is molten for soldering the surface of the cap 21 and the back surface of a semiconductor chip 10 to the rear of a heat dissipation plate 14, the leftover solder 16, which does not contribute to the soldering of the surface of the cap 21 and the back surface of the chip 10 to the rear of the plate 14, flows in the trap 21b of the cap 21 and does never flow down on the inner side surface of the cap 21. For this, a short-circuit between leads 10a is never caused by the solder 16.

Title: Densitometer
Inventor: UEKI YOSHIHARU
IPC: G01N21/47
Filed: 1991-12-19
Abstract: PURPOSE:To improve the stability with time of the measuring accuracy of the density value, and to improve the operating efficiency remarkably by correcting the detecting intensity of the reflecting luminous flux from a to-be-measured object by the intensity of light from a light source which casts light to the to-be-measured object. CONSTITUTION:One of red, green and blue colors of the reflecting luminous flux from a sample 15 is taken out by a filter part 14 provided at an upper part 2c of the casing of a measuring head 2. Thereafter, the reflecting light is introduced into a photosensor 22 to measure the intensity of light of each color. The measured values are output to a sensor signal processing part. At the same time, the light from a light source lamp 12a is introduced to a photosensor 2 for the light source lamp via an optical fiber 16, and the intensity of light is measured and output to the sensor signal processing part. The detecting intensity of the reflecting luminous flux from the sample 15 (output of the sensor 22) is corrected by this intensity of light measured by the sensor 21. Accordingly, even when the intensity of light of the lamp 12a is changed, the stability with time of the measuring accuracy of the density value or the sample 15 is improved. The correcting (calibrating) number of times of outputs of 22 can be small, and the operating efficiency of the densitometer is remarkably improved.

Title: Picture reader
Inventor: INOUE YOSHIO
IPC: H04N1/04
Filed: 1993-12-28
Abstract: PURPOSE:To apply optimum read scanning to an original placed with a tilt and to correct the tilt of the original with simple picture signal processing. CONSTITUTION:An image sensor 56 is tilted by a same angle theta in matching with a tilt theta of an original S on a glass plate R. Then the image sensor 56 is moved in a direction of a shaft 42 and simultaneously in a main scanning direction x'. Tilt scanning in matching with a tilt angle of the original is implemented by controlling the movement in both the directions interlockingly with each other. The tilt scanning is realized by tilting the shaft 42 by an angle theta. On the other hand, the image sensor while being tilted is scanned in the subscanning direction and a read range is corrected for the picture signal in this case, resulting that the similar result to the case with the tilt scanning is obtained. The propriety of scanning is discriminated prior to each scanning.

Abstract: PURPOSE:To obtain an automobile head lamp provided with a level having less measurement error even by any temperature of the circumferential atmosphere of the level by applying a heat releasing grease onto the outer circumference of a bubble tube received in the casing of the level. CONSTITUTION:A heat releasing grease 100 having a satisfactory heat conductivity is applied onto the outer surface of a bubble tube 80 except the scale formed surface thereof, and the heat releasing grease 100 smooths the difference in the conducted heat quantity in each area. Namely, the highly heat conductive heat releasing grease 100 conducts the heat quantity of the same degree as that in the area having a short heat conducting passage to the area having a long heat conducting passage, so that the difference in the heat quantity conducted to each area of the bubble tube 80 is minimized. Thus, the quantity of heat conducted to the bubble tube 80 is longitudinally uniformed, reducing the temperature difference between front and rear end parts of the bubble tube 80. Therefore, in the bubble tube 80, no convection resulting from the temperature difference is generated, and movement of bubbles is hardly present.
