Title: Electrostatic adsorption conveying device
Inventor: USUI SATOSHI
IPC: B65H5/00
Filed: 1988-08-13
Abstract: PURPOSE:To eliminate repair of an electrode at a joint part, to increase the discharge speed of a charge, and to facilitate discharge of sheets by a method wherein a plurality of endless belts formed by a semiconductive material are located in juxtaposition, and voltages different from each other are applied on the circumferentially continuous electrodes of the adjoining belts. CONSTITUTION:Electrodes 6b in a rowlike manner continuous throughout a whole area in a circumferential direction are formed on each endless belt 6. Voltages different from each other are applied on the electrodes 6b of the adjoining belts 6, and feed is made throughout a whole area in the direction of the length of the belt 6. As a result, a work to repair the electrode at a joint part is eliminated. Further, since a charge leaks through the electrode 6b having low resistance, the discharge speed of a charge is increased, and when a sheet is separated in a state to bring a voltage into an OFF-state, the sheet can be relatively rapidly released from an adsorbed state, resulting in facilitation of discharge of sheets.

Abstract: PURPOSE:To permit erasure of recording information only on the arbitrarily selected face over the entire surface without affecting the recording information on the other face by using compsns. which are different in coercive force to constitute the magneto- optical media on the respective faces of the magneto-optical memory medium formed with the magneto-optical medium layers on both the front and rear faces. CONSTITUTION:The coercive force of the magneto-optical medium 3 on one face is preset in the state of the high coercive force A and the coercive force of the magneto-optical medium 4 on the other face in the state of the high coercive force B or C. The intensity H of the external magnetic field at the time of erasing is set at Ha<H<Hb and is impressed over the entire surface of the magneto-optical disk in the case of erasing the recording information on the face in the state of A over the entire surface without affecting the other face side in the state of B. No magnetical influences are thereby exerted to the magneto-optical medium 4 at all, but the recording information on the magneto-optical medium 4 at all, but the recording information on the magneto-optical medium 3 side is erased over the entire surface. Erasure of only the recording information on the face side in the state of B is executed by increasing the atmosphere temp. by DELTAT and erasing the information in the state of reversing the high and low coercive force of the front and rear faces.

Title: Alkaline battery
Inventor: HARADA MASATO
IPC: H01M6/04
Filed: 1981-12-15
Abstract: PURPOSE:To increase the second stage discharge of managanese dioxide in low rate discharge to improve discharge capacity by adding triethanolamine to an electrolyte of an alkaline battery using manganese dioxide as one of positive active masses. CONSTITUTION:Triethanolamine is hygroscopic and absorbes carbon dioxide and has higher viscosity than water. It is difficult to diffuse uniformly when triethanolamine is mixed to highly concentrated alkaline solution having higher viscosity. In consideration of above mentioned property and solubility, 5-15pts.wt. of triethanolamine is mixed to 100pts.wt. water to form an aqueous solution, then added to an alkaline solution. When the adding amount of the triethanolamine solution is too much, internal resistance of a battery is increased and discharge capacity is decreased. When the adding amount is too little, effect of addition can not be achieved. Therefore, addition of 0.1-1.9pts.wt. triethanolamine solution to 100pts.wt. alkaline solution is preferable. Manganese dioxide, mixture of mercuric oxide and manganese dioxide are used as an positive active mass.

Title: Simulation circuit for sonar echo
Inventor: TOYODA TOSHIBUMI
IPC: G01S7/52
Filed: 1992-07-08
Abstract: PURPOSE:To achieve sound quality equivalent to that of actual sonar echo. CONSTITUTION:A delay circuit 2 operates time lags of sonar echo behind sonar pulse for various targets. A highlight generator 3 generates an echo having time lag operated at the delay circuit 2 for each target and controls the amplitude of the echo. A white noise generator 6 and a bandpass filter 5 produce a random signal in a predetermined frequency band. The random signal is then subjected to amplitude control through an amplitude control means depending on an output signal from the highlight generator 3. With such arrangement, frequency spectrum of echo varies significantly as the pulse width taup of oscillation wave shortens like an actual echo and thereby frequency bandwidth is enlarged resulting in a sound quality substantially equivalent to that of an actual echo.
