Title: Copying device with partially erasing function
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/04
Filed: 1984-02-28
Abstract: PURPOSE:To erase desired information at a high resolution even at the time of variable power copying, by providing a luminous flux deflecting means facing to the optical path of the projected luminous flux of an original image and arranging plural color information reading elements at the image forming position of luminous fluxes deflected by the deflecting means. CONSTITUTION:A projected scanned optical image is connected at color information reading elements 25 through a prism block 24 so that the light receiving position of the elements 25 and irradiating position of a photosensitive drum 21 by light irradiating elements 27 become optically equivalent to each other. Since each of the color information reading elements 25 and light irradiating elements 27 are arranged in the same pitch so that they can correspond to each area of the projected scanned optical image one by one, color information can be detected at a high resolution with no error. Moreover, desired picture erasion can be performed with high accuracy by directly controlling the lighting of the paired light irradiating elements with a simple circuit configuration without making any adjustment on position and time by using the information, and, at the same time, the mechanical constitution can be simplified.

Title: Sound equipment with telephone set
Inventor: NAKAGAWA SUSUMU
IPC: H04B1/16
Filed: 1986-02-20
Abstract: PURPOSE:To pick up a sound signal having an enough high level even in a call, when a plug is inserted into an earphone jack, by providing a switch means which blocks the function of a mute command means. CONSTITUTION:When an earphone plug, etc., is inserted into the earphone jack, a switch 7 is opened, and a capacitor 6 is charged through a resistor 12, and a voltage at a point A goes to almost the same level as that of a voltage source Vcc. In such a state, even when a handset is raised to perform the call, and a mute signal goes to Hi, and a transistor 1 goes to a short- circuited state, the voltage at a point B, that is, a sound volume setting voltage is prevented from dropping because the voltage at the point A is almost equal to the voltage source Vcc. Since the sound volume setting voltage is prevented from dropping, the output level of a sound amplifier 13 is lowered, thereby preventing the generation of a mute state.

Title: Agent for deodorizing permanent wave lotion
Inventor: UEISHI YUKIO
IPC: A61K8/46
Filed: 1983-03-05
Abstract: PURPOSE:To provide an agent for deodorizing a permanent wave lotion containing a mercapto compound as a main agent, by using one or more germanium compounds, antimony compounds or bismuth compounds as a component. CONSTITUTION:A deodorizing agent consisting of one or more germanium compounds, antimony compounds or bismuth compounds (e.g. germanium dioxide, antimony chloride, etc.) is added to a permanent wave lotion containing a mercapto compound as a main agent. The characteristic ill-odor of mercapto compound and the unagreeable smell and after-odor of hydrogen sulfide can be removed easily without lowering the merits of a permanent wave lotion containing a mercapto compound having strong reducing power, e.g. thioglycolic acid, cysteine, etc. as a main agent. Furthermore, the deodorizing agent hardly forms a complex with the mercapto compound, and consequently, the blocking of the thiol group and the lowering of the waveforming capability can be prevented.

Abstract: PURPOSE:To increase the precision of the analysis by catching precisely the increase value of an electrode base corresponding to the glucose component concn. value in a decomposing coenzyme or a specimen, and performing a calibrating operation including correction thereto. CONSTITUTION:An electrode 1 is installed to a reaction cell 3, and a buffer soln. in a bottle 5 is introduced into the reaction cell 3 through a liquid pump 2. When a liquid contg. amylase and a decomposing coenzyme e.g. glucoamylase are introuced at the same time, a chemical reaction is caused. And, when the formed hydrogen peroxide H2O2 is oxidized on the electrode 1, a current proportional to the amt. of the glucose flows. The current is amplified by an amplifier in a control part 6, converted into a digital amt. by an A/D converter, then data- processed by a CPU. The increased amt. of the output is detected by using an amylase standard soln. of which concn. value is already known. Even when the glucose or the decomposing coenzyme is introduced independently, the output of the electrode is increased. The real current output increment DELTAA is the value obtained by subtracting the latter two from the former.
