Title: Electrostatic recording system
Inventor: SAITOU SUSUMU
IPC: B41J2/40
Filed: 1984-03-05
Abstract: PURPOSE:To enable a halftone recording by a method wherein a pulse voltage is applied to a control electrode several times while a pulse voltage is applied to a recording electrode in the opposite polarity when the pulse voltage corresponding to the round selected according to the recording density is applied among those pulses. CONSTITUTION:When a trigger pulse is inputted, a store address for one block from an address generation circuit 12 is inputted into a memory 11 and halftone image signals are outputted sequentially. A density level D3 is outputted as reference level from a reference level generation circuit 13. The signals are changed to a black/white binary image signal with a comparator 14 based on the pixel given 1 to the D3 of the density level. Then, a recording electrode driving circuit 16 operates to apply a pulse voltage VS is only to that of recording electrodes in each block corresponding to the signal ''1'' and at the same time, a pulse voltage VC is applied to a control electrode with a control electrode driving circuit 17. Subsequently, with the density levels D2 and D1 as reference levels respectively, pulse voltages VS and VC are applied in the same way. Thus, a halftone recording can be done by three times of record driving.

IPC: G08C17/00
Filed: 1980-03-31
Abstract: PURPOSE: To reduce a turning radius, by a method wherein a pair of projections, which can protrude downward from the body, are mounted, and are caused to contact with the ground for turning.  
     CONSTITUTION: A pair of projections 3, which can protrude downward from a body 1, are attached at both right and left sides in the proximity of the bottom center of the body 1. Either of the projections is driven for downward protrusion according to the steering direction thereupon by means of a driving mechanism 5. Or, only the projections 3, positioned at the inner side of the turning, is caused to protrude so that front and rear wheels, positioned at the same side as that of the projection, are caused to float and a vehicle turns with the projection 3 pivoting. The turning radius does not depend upon a distance between the wheels, and as a result, the turning radius can be reduced substantially.

Title: Controlling method for absorption refrigerator
Inventor: YAMAUCHI AKIRA
IPC: F25B15/00
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To promote the temperature increase of a high-temperature reproducing equipment on activation and to reduce time required for the activation by measuring the temperature of the high temperature reproducing equipment and controlling the opening of a solution bypass valve according to the measured temperature of the high-temperature reproducing equipment when started operation. SOLUTION: When the power of an absorption refrigerator that has been stopped is turned on, a solution bypass valve 39 is automatically opened regardless of the temperature of an evaporator 34 and is kept open while it is opened until the temperature of a high-temperature reproducing equipment 10 reaches a preset temperature. Therefore, a dense solution is not sprayed onto a cooling water coil 46 of an absorber 44 and is bypassed to the lower part of the absorber 44, thus preventing the heat of absorption solution that is guided to the absorber 44 from being removed by a coolant that flows in the coolant coil 46. The absorption solution bypassed to the lower part of the absorber 44 is fed to a high-temperature reproducing equipment 10 without the heat being removed by a solution circulation pump 54 and is heated.

Inventor: OIKAWA TOMOO
IPC: B24B3/36
Filed: 1994-02-15
Abstract: PURPOSE:To facilitate linear grinding of an edge by grinding the main bevel and temporary edge of a knife using a grinding wheel set to a predetermined main-bevel angle (edge angle), then making a finishing grinding wheel abut the right and reverse sides of the edge for the grinding of micro bevels on the right and reverse sides of the edge. CONSTITUTION:In grinding the edge of a veneer lathe knife 1, the long-sized knife is supposed to have a standard reverse side 14 and a main bevel 7 is ground at a predetermined angle to the standard reverse side 14 of the knife. Next, a right side micro bevel 12 is ground on the right side 11 of the edge at a predetermined right-side micro-bevel angle to the surface of the main bevel 7 (an irregularity or distortion then appears at a temporary edge 5b consisting of the micro-beveled surface on the right side of the edge and the reverse side of the knife). Next, a reverse side micro bevel 13 is similarly ground on the reverse side of the edge, and thus the knife is edged right along its longitudinal direction with the edge position set inside the intersection of the standard reverse side 14 of the knife and the surface of the main bevel 7.

Title: Method for heating semiconductor wafer
Inventor: ARAI TETSUHARU
IPC: H01L21/26
Filed: 1983-03-16
Abstract: PURPOSE:To enable the good heating of the whole surface of the wafer with uniform temperature as well as to prevent overheat of the part not-requiring heating by providing a film on a surface of the wafer thereby uniformizing the reflectivity, after which the wafer is irradiated with flashing light to be heated. CONSTITUTION:A film 7 consisting of silicon oxide of about 0.2mum thick is formed over the whole surface of a wafer 6. Next, the wafer 6 covered with the film 7 is held at a wafer holding part of a sample table 5 in a heating oven and is heated preliminarily by a heater of the sample table 5 prior to irradiation with the flashing light. When the temperature of the wafer 6 reaches about 350 deg.C, it is heated by the irradiation with the flashing light over the whole surface by a light source S of the flashing light plane. With respect to this flashing light irradiation, it is a logical background that the reflectivity of a surface of the region requiring heating of the wafer 6 becomes about 0.31 whereas that of the region not-requiring heating is about 0.31. Accordingly, the reflectivity of a surface of the wafer 6 becomes about 0.31 uniformly over the whole surface, resulting in the reached temperature of the wafer 6 being uniform over the whole.

Filed: 1991-02-15
Abstract: PURPOSE: To provide an inexpensive digital amplitude adjusting device by adjusting the gain of an amplifier by adjusting the transfer characteristics of a diode by a sub-continuous variable DC voltage in which a duty cycle variable pulse column is generated. CONSTITUTION: A diode 46 is non-conducted, and the AC components of an input signal are not allowed to reach a node 40 and an arithmetic amplifier 26 as long as a voltage in a node 22 is less than the DC voltage components of the input signal in a variable duty cycle pulse duty cycle. The amplitude of the reference voltage of a node 22 is made larger than that of the DC voltage components of the input signal according to the increase of the duty cycle, and the diode 46 is conducted. Then, DC currents are allowed to flow as bias currents Id of the diode 46 through a resistance 48, diode 46, and resistance 42. The amplitude of the currents Id is directly changed according to the amplitude of the reference voltage of the node 22.  The value of the resistance 48 is selected to be large so that the amplitude of the currents Id can be maintained to be small, and that only the small change of the currents Id can be generated by the small fluctuation of the voltage of the node 22.
