Title: Electrophotographic copying method
Inventor: KUROKAWA JIYUNJI
IPC: G03G13/02
Filed: 1981-12-28
Abstract: PURPOSE:To obtain uniform density of pictures even in the stage of continuous copying of plural sheets by preventing the fluctuations in the electrostatic charging potential of a photoreceptor simply by changing the operating sequence of an existing device. CONSTITUTION:When an electric power source switch of a copying machine is turned on, a photosensitive drum 1 starts rotation at a specified speed; at the same time, a corona discharger 12 and a destaticizer 8a start operation. Then, the photoreceptor is precharged to a negative polarity by the discharger 12 and is irradiated with green color light by the destaticizer 8a, whereby negative electric charge is captured in the trap 9 in the photosensitive layer 1a. Since the surface of the photoreceptor is charged uniformly to the polarity reversed from the charging polarity and is then irradiated with the green color light prior to starting of the copying process, the charge is filled in the trap in the photoreceptor, and the charging potential of the photoreceptor is decreased to approximately the same value as the value in the steady stage; thereby, even when plural sheets are copied continuously, the densities of the pictures among the respective copies are uniform.

IPC: G06F9/52
Filed: 1990-08-10
Abstract: PURPOSE:To accurately and exclusively control a shared resource without interfering the execution of a process with low precedence by repeating a processing issuing a WAIT command for a monitor till the WAIT command is normally restored after an RECV command is abnormally restored. CONSTITUTION:When more than three processes 1 are to simultaneously and exclusively occupy the same resource 3, the process 1 which intends to occupy the resource 3 in third and succeeding turn is compulsorily set to a standby state by a timer 6 for timer time corresponding to a timer value Tw being the parameter by the issue of the RECV command.

Title: Production of sintered compact baked at wide temperature zone using glass particle as raw material
Inventor: HANAOKA KOKICHI
IPC: C04B33/13
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To enable the reuse of glass obtained from waist glass, etc., the baking at wide temperature zone, the reduction of the discharge of carbonic acid gas at a low temperature range and the use of glass as constructional material for building by baking a molded body produced using a specific molding raw material. SOLUTION: Glass granules generated in a glass manufacturing process, etc., and glass granules obtained by crushing waste glass, having an average particle diameter of 2-5mm, are used as raw materials. These granules with the upper limit of weight ratio of 80wt.% are kneaded with ceramic clay such as potter's clay, kibushi-clay or bentonite while adjusting water content to obtain a raw material for molding. A molded body produced from the obtained raw material for molding by wet extrusion molding or dry press molding is baked at a temperature in a wide temperature zone such as 700-1300 deg.C, and this process enables the control of baking by combining perfect sintering and partial sintering.  That is, low temperature baking such as at about 700 deg.C gives lower strength than high temperature baking, but it reinforces the strength by the melt of glass and gives a sintered compact having a specific decorative effect.

Title: Drive circuit for piezoelectric transformer
Inventor: IGUCHI KOICHI
IPC: G02F1/133
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To reduce the heat loss of a piezoelectric transformer which inputs an AC voltage from primary electrodes and outputs a transformed voltage from secondary electrodes through the utilization of piezoelectric effect by driving the transformer with a transformed voltage of the transformer. SOLUTION: An input power control section 20 controls drive voltages vd1 and vd2 which are generated from primary electrodes 401 and 402 of a piezoelectric transformer 40, so that they do not depend on a power supply voltage Vcc. When a resonance circuit is formed of the inductance of a coil 33 and the equivalent capacity between the primary electrodes 401 and 402 of the transformer 40, a transistor 21 is normally turned off and the current path going toward the primary electrode 401 from a power source 10 through the coil 33 is disconnected. Similarly, when a resonance circuit is formed of the inductance of a coil 34 and the equivalent capacity between the primary electrode 401 and 402 of the transformer 40, a transistor 22 is normally turned off, and the current path going toward the primary electrode 402 fro the power source 10 through the coil 34 is disconnected.  Therefore, an excess current can be prevented from flowing in the transformer, and the heat loss of the transformer 40 can be reduced.
