Title: Semiconductor integrated circuit
Inventor: NISHIKUBO TETSUYA
IPC: H03K5/08
Filed: 1989-08-18
Abstract: PURPOSE:To prevent a through-current flowing when a level of an input terminal of a semiconductor circuit having MOS structure is an intermediate level by detecting the intermediate level and outputting a detection signal. CONSTITUTION:When a level of an input terminal 3 is an intermediate level, a through-current flows from a Vcc to GND via a resistor 7, a P-channel transistor (TR) 5 and an N-channel TR 6, a voltage drop is caused by the through- current and an input 10 of an inverter 10 is brought into an 'L' level. The level of the input 10 is selected not to turn off the P-channel TR 5 and a threshold voltage of the inverter 8 is selected to decide the said level to be an L input. Thus, the level of the output 9 goes to 'H' and a gate of a P-channel TR 11 and of an N-channel TR 12 goes to an 'H', the P-channel TR 11 is turned off and a through-current flowing from the Vcc to the P-channel TR 1 and the N-channel TR 2 to GND is blocked.

Abstract: PROBLEM TO BE SOLVED: To make a sufficient keeping of a flow passage area of an opening refrigerant passage for connecting a refrigerant opening hole formed at an end plate of a heat exchanger with an opening pipe at an outside part of the heat exchanger and to cause an amount of material applied for forming the end plate to become minimum as needed. SOLUTION: A first passage forming plate 31 having expansion segments 31b, 31c is coupled to a second passage forming plate 32 having expansion segments 32b, 32c while being abutted to each other. An inlet refrigerant passage is formed by a space enclosed by the expansion segments 31b, 32b, and an outlet refrigerant passage is formed by a space enclosed by the expansion segments 31b and 32c. With such an arrangement as above, a sufficient flow passage area of each of the refrigerant passages can be kept and further these refrigerant passages are formed without using an end plate 131, so that it is possible to cause a thickness of the end plate 131 to become minimum.

Abstract: PURPOSE:To make the direction of optical signal transmission nonreciprocal by a purely electro-optic element and to perform unidirectional transmission by applying driving signals which are correlative with each other in terms of time to two electro-optic elements. CONSTITUTION:Light incident from a side 1 is gated or modulated by an electro- optic element G1 firstly, delayed by a specific time by passing through an optical transmission line OD, and gated or modulated in the current moade by an electro-optic element G2. Light incident from a side 2 is also gated or modulated similarly. Then when transmission coefficients of the elements G1 and G2 vary within the propagation time of the transmission line OD, total transmission coefficients in the forward and backward directions are in mutually different relation. For the purpose, the difference in total transmission coefficient is utilized to constitute a nonreciprocal optical transmitter which differs in transfer coefficient or transmission coefficient according to the propagation direction of incident light.

IPC: H04N5/208
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To automatically correct the deviation of an optimum contour correcting amount due to the change of the display of the background of a video signal. SOLUTION: A correcting parameter is set in a state in which contours of images on a CRT screen are the most easy-to-see in a setting circuit 2 in a state in which black characters are displayed in a white background. In this case, when an arithmetic means 51 judges that the screen displays black characters in the white background, the contour correcting device maintains the state of the setting circuit 2. When it judges that the screen is changed over to a state where the screen displays white characters in a dark background, a contour correcting circuit 1 obtains optimum contours in real time by correcting the correcting parameter of the setting circuit 2.

Abstract: PURPOSE:To prevent adverse effect on a photosensitive body and image quality due to the variance in distribution of contact pressure on the photosensitive body of a sliding contact part by mixing looped fiber and straight fiber in the sliding and abrading part. CONSTITUTION:The cleaning brush 4 is constituted by winding the loop state fiber 11 made of many loops 13 formed by weaving in fiber to a base material 12 in a spiral state to a peripheral surface of a core metal 10 consisting of a metal roller. Then, in the sliding abrading part A of the loop state fiber 11 to the photosensitive body 1, 5% to 50% of the loops 13 are cut, thus, the part is constituted of a mixture of the looped fiber 13b and the straight fiber 13c.

IPC: F15B11/04
Filed: 1981-12-29
Abstract: PURPOSE:To realize prevention of shock and vibration by setting the switching time to a constant value and allowing a fractional pressure change within said time by controlling the flow step by step. CONSTITUTION:The switching time T is set to a constant value and speed control is performed through control of a flow V only. In this case, flow control during the switching time T is repeatedly performed step by step from the high- speed side to the low-speed side by a predetermined set value K. The set value K is to be determined, for example, within 1/2 of the set flow at 0-7.5% of a pump discharge quantity and the speed is decreased by a step equivalent to the set value K. In this case, the smaller the set value K is, the slower becomes the switching speed, thus being accompanied by reduction in occurrence of shock  and vibration.

Abstract: PURPOSE:To maintain stable developability by interlocking a vibration diaphragm and toner sensor and stopping and operation of the vibration diaphragm when a specified amt. of a toner is detected by the sensor. CONSTITUTION:The one-component magnetic toner 5 is supplied from the upper part of a hopper 2 and falls onto the lower hopper when the vibration diaphragm 10 operates. Whether the prescribed toner amt. is attained or not is detected by the toner empty sensor 15. The operation of the diaphragm 10 is stopped when the prescribed amt. is attained.
