Title: Manufacture of detergent additive tablet
Inventor: HANSU KURUUSE
IPC: C11D17/00
Filed: 1985-05-14
Abstract: A powdery activator for per compounds is granulated by, at the same time, mixing it together with nonionic surface-active compounds certain nitrogen-containing compounds and, optionally, the water-soluble salt of an alkane polyphosphonic acid. The granulate thus obtained is powdered with a powdery absorbent and the powdered granulate is sprayed with a liquid binder and dried to a water content of at most 6% by weight. After the addition of a tablet disintegrating agent, the dried granulate is formed by compression under special conditions into tablets having special properties. When added to a wash liquor containing a standard detergent containing a per compound, the tablets improve the removal of fatty/oily stains, pigment-containing soil and bleachable stains.

Title: Terminal equipment of computer
Inventor: YAMAKOSHI KAZUNARI
IPC: G06F3/02
Filed: 1987-04-27
Abstract: PURPOSE:To eliminate the fatigue of users and to avoid the input mistakes and deterioration of the developing efficiency, by deciding the working situation of a computer terminal equipment and stopping the working of an input device based on the result of said measurement. CONSTITUTION:A program monitors a keyboard 21 and counts the number of input characters. This counted number of input characters is compared with the set stop interval stored in a stop interval memory means. When said count value is larger than the set stop interval, a rest time is decided. Thus the program neglects the input received from a keyboard 21 and inhibits the transmission of the keyboard input to a host computer 24 from an I/O channel 23. Then a message is displayed on a CRT display device 22 to urge the rest.

Title: Gain characteristic compensating circuit for amplifier
Inventor: KATO TAKAO
IPC: H03G3/30
Filed: 1988-04-28
Abstract: PURPOSE:To compensate the fluctuation of a gain characteristic held by an amplifier without damaging the characteristic held by an amplifying signal by supplying a detection output through a time constant circuit to a gain control circuit. CONSTITUTION:A high frequency AM signal supplied from an input terminal 1 is supplied through a distributor 2, for example, to a gain control circuit 3 composed of a PIN diode and the output signal of the gain control circuit 3 is introduced and amplified and taken out from an output terminal 5. On the other hand, a part of the output of the distributor 2 is detected by a detector 6 and for example, supplied through a time constant circuit 7 composed of an LC element, etc., to the gain control circuit 3 as a control signal. Here, the time constant circuit 7 compensates the gain control of the gain control circuit 3 only for the fluctuation of the output waveform of the detector 6 beforehand. Thus, without deteriorating the video signal characteristic of an AM wave, the gain characteristic of an amplifier 4 can be compensated.

Title: Pretransfer electrifier for electrophotographic device
Inventor: KATO KOJI
IPC: G03G21/00
Filed: 1993-04-30
Abstract: PURPOSE:To realize high quality print by providing an electrifying member which, before the emission of fade light, applies an AC voltage which is biased on the side of the same polarity as toner, thereby decreasing scattering of toner around a toner image. CONSTITUTION:A corotron 6 to which an AC voltage is applied produces positive and negative coronas. The positive corona is attracted to a high-negative polarity area on a photosensitive body 1, and the negative corana to a high- positive polarity area, so that electrical neutralization takes place. Therefore, because the negative polarity is high on a toner image, the positive corona is attracted to neutralize charges, and repulsion becomes weak, so that scattering of toner around the toner image decreases. Here, in order to increase the amount of corona of the same polarity as toner, an alternating current in which biases are superimposed on side of the same polarity as toner is applied to the corotron 6 by an AC voltage power source 7.

Abstract: PURPOSE:To obtain high-temperature heat even in case sunshine is weak and air passing through a box type body is not heated sufficiently, by providing the heat exchanging section of a heat pump in the box type body, covered by a transparent plate and heating air. CONSTITUTION:In the sunshine, the air passing through the box type body 4 absorbs solar heat, reserved in a heat-collecting body 3, and the heated air exchanges a part of the heat thereof with heat medium passing through the heat exchanging section 10 during passing through the heat exchanging section 10 of the heat pump 9, while the residual of heat is delivered from an air exit port 7 through a duct 44 into a room R to condition the air in the room R. When sunshine is weak, such as in morning, evening or the like, the air conditioning of the room is stopped and only the heat pump 9 is driven. The air in the box type body 4, which receives weak solar light, is heated to a low temperature and the latent heat reserved in the low-temperature air is absorbed by the heat medium, passing through a tubular body, while the heat medium reaches high temperature in the main body 13 of a unit to heat supplying hot-water communicated with a heat-accumulating tank 14, whereby the temperature of the supplying hot-water may be raised to a temperature higher than the temperature of air existing in the box type body 4.

Title: Current position display device for moving body
Inventor: HIJIKATA YOICHI
IPC: G09B29/10
Filed: 1992-04-23
Abstract: PURPOSE:To secure a chance to correct the output of an azimuth sensor even when the current position is estimated by taking in the output of the azimuth sensor at a high speed. CONSTITUTION:Two tracks are generated by connecting alternate estimated positions Pi (i=1, 2...) estimated on the basis of the outputs of a distance sensor and the azimuth sensor. When a vehicle turns, the time difference DELTAtheta between the tracks is nearly zero, but when the vehicle is turning, the time difference DELTAthetaexceeds a threshold value thetath. For the purpose, this difference DELTAtheta is decided by using the threshold value thetath to detect a straight travel. The points Pi are connected by turns, so the sensitivity of the straight travel decision for the azimuth sensor output is decreased and it is hardly decided that the vehicle is in process of turning owing to the passing of a pedestrian. The two tracks are used, so the position precision can be improved by the high-speed detection.
