Title: Electrostatic charging method of photosensitive body
Inventor: KUROKAWA JIYUNJI
IPC: G03G15/02
Filed: 1983-12-27
Abstract: PURPOSE:To protect a photosensitive body against ozone, etc., produced in discharging operation and hold copy quality excellent, and prolong the life of the photosensitive body by coating the photosensitive body with a thin film of electric insulating oil having low viscosity prior to the discharging operation. CONSTITUTION:When copying operation is performed repeatedly, ozone produced in the discharging of an electrostatic charger 3 causes the photosensitive body 2 to deteriorate and moisture absorption occurs to deteriorate charging characteristics, exposure characteristics, and other copy characteristics, lowering image quality. An oil coating device 9 is provided at the upstream position of the charger 3 so as to evade the photosensitive body deterioration, and the surface of the photosensitive body 2 before the charging operation is coated with a thin film of transparent oil which has watertightness and provides electric insulation. Consequently, the photosensitive body 2 itself is protected by the oil film and affected by neither ozone nor moisture absorption, and the oil film is transparent, so copy quality is held excellent without any deterioration in charging characteristics.

Abstract: PURPOSE: To prolong service life of a hose by providing a bundle of spray lances which are connected to the coupling element in the line of a high pressure hose and which carry spray heads at their free ends and drive means for a hose drum and driving the coupling element synchronously during unwinding operation of hose. CONSTITUTION: End part of a spray lance 13 fixed with a spray head is inserted into the tube 16 of a heat exchanger 17. When the switch of a high pressure pump us turned on, a bundle of spray lances is moved to the left by a drive means 20 and the spray head 16 is moved forward through the tube 16. Consequently, deposits in the pipe 16 are stripped and washed out by cleaning water flowing out from a nozzle under high pressure. When a coupling member 12 approaches a guide block 14 at the end of stroke, the switch of the high pressure pump is turned off and the spray lance 13 is returned back to wind a high pressure hose 5 around a hose drum 2. The coupling member 12 is driven to the left simultaneously with driving of the drum in the unwinding direction thus releasing the coupling member 12 and the drum 2 from tensile load or pressure load.

IPC: C22F1/00
Filed: 1990-09-14
Abstract: PURPOSE:To attain grain refining in a base phase and to allow superplasticity capable of providing large deformation with minimal stress to appear by finely precipitating alpha-phase at a temp. not higher than isothermal working temp. before applying isothermal working to a preworked beta titanium alloy. CONSTITUTION:Preworking is applied at >= about 70% draft to a beta titanium alloy at a temp. in the temp. region where working is relatively easy and an alpha-phase is hardly precipitated and then to precipitation treatment at a temp. in the (alpha+beta) two-phase region between about 400 deg.C and the beta-transformation point, by which the alpha-phase is precipitated finely and uniformly.

Filed: 1989-09-22
Abstract: PURPOSE:To realize formatting with a constant format area for a user by detecting the rotational cycle of a first servo pattern as reference, and writing a second servo pattern at a timing of 1/2 the rotational cycle. CONSTITUTION:A microcomputer 1 fetches index time for two times setting a motor index signal 6 from a motor driving circuit 5 as reference.

Filed: 1983-12-28
Abstract: PURPOSE:To attain stable initial synchronous drawing and phase correction in a normal time in an MODEM device etc., by not using a limiter circuit at the time of initial synchronous drawing and using the limiter circuit after initial synchronous drawing. CONSTITUTION:At the time or initial synchronous drawing, a change-over circuit 515 is controlled by a controlling circuit not shown in the figure, and supplies a phase difference signal outputted by a phase difference detecting circuit to an integrating circuit 50. As the integrating circuit 50 generates an integration signal corresponding to the magnitude of the phase difference signal, the integration signal is supplied to a trigonometric function generating circuit through an adder 514, and a correction signal corresponding to the magnitude of the phase difference signal is obtained. On the other hand, when initial synchronous drawing is completed, a controlling circuit, not shown in the figure, switches the change-over circuit 515 from the integrating circuit 50 to an integrating circuit 51. When switching of the integrating circuit is made, an integration signal of the integrating circuit 51 is outputted in a short time through the adder 514, and accordingly, a stable correction signal can be generated even after switching of the integrating circuit.

Abstract: PURPOSE:To prevent a phenomenon that a shirt a person is wears is pulled upward when the person, seating on a chair, lens on a backrest. CONSTITUTION:A seat body 3 interlocked with a backrest 4 inclined rearward is moved rearward while being inclined rearward. When a person leans on the backrest 4, a vertical length dimension L on the surface of the person's skin from the neck to the hip tends to be shorten by the tendency of elongating his body. A change in the length dimension L of the surface of the person's skin from the neck to the hip is offset by the rearward movement of the seat body 3. As a result, the person's shirt is not pulled upward so that the person can be prevented from uncomfortable feeling.

Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanging ventilation system in which ventilation rate of a bath room can be increased appropriately in correspondence with the operating mode of a bath room air conditioner, or the like. SOLUTION: The heat exchanging ventilation system comprises a duct 3 for exhaust indoor air to the outside, a duct 2 for supplying outdoor air to a habitable room, and a ventilation unit 1 for exchanging heat between the indoor air and the outdoor air through a total heat exchanger 12 wherein the air in a bath room being supplied through a bath room exhaust duct 36 can be fed to the total heat exchanger 12 side or the bypath 15 side through a damper mechanism 5.
