Title: Control circuit for stepping motor
Inventor: SUZUKI HIROSHI
IPC: H02P8/06
Filed: 1984-05-09
Abstract: PURPOSE:To reduce power consumption and to improve the driving accuracy of a stepping motor by stopping the supply of an exciting voltage at standby state time, and providing control means for supplying a rated exciting voltage for the prescribed time immediately after the standby state is eliminated. CONSTITUTION:A voltage supply to a switch circuit 24 is stopped in a standby state. When a motor start signal MO is output, an exciting voltage V of a high level voltage Va is supplied to a motor drive circuit 20 during a time interval T2 determined by a multivibrator 28. Thus, a stepping motor 21 is rotatably driven at a high torque, and a magnetic head is accurately positioned on a specific track in the standby state. A switch 24 outputs a low level voltage Vb to a switch circuit 23 in nonseek operation state. When a step pulse inversion SP necessary for seeking operation of a magnetic head is output, an exciting voltage V of a high level voltage Va is supplied to a motor drive circuit 20.

Filed: 1983-05-27
Abstract: PURPOSE:To obtain very highly purified gaseous Ar as a product by introducing gaseous Ar contg. N2 as a starting material to be purified into a mordenite type zeolite layer at a low temp. to adsorb N2, increasing the temp. of the zeolite layer to desorb the adsorbed N2, and repeating the operations. CONSTITUTION:Gaseous Ar contg. N2 as a starting material to be purified is introduced into an adsorption tower 1 cooled 3 to <=-20 deg.C by suction and discharge with a blower 2 while keeping the whole system under atmospheric pressure or above. In the tower 1, N2 in the gaseous Ar is selectively adsorbed on packed mordenite type zeolite, and Ar contg. no N2 is allowed to flow out 5 and fed to a product Ar duct 8. After introducing a fixed volume of the gaseous starting material into the tower 1, a closed circuit consisting of the blower 2, a heater 4 and the tower 1 is formed, and gas discharged 2 is heated 4 and introduced into the tower 1 to heat the tower 1 to >=0 deg.C. Gas flowing out 5 of the tower 1 is circulated again to the suction side of the blower 2 to release the adsorbed N2 and Ar from the tower 1. When the tower 1 attains to a prescribed regeneration temp., pure Ar is introduced 20 into the tower 1 to desorb residual N2 of high concn., and after cooling the tower 1 to the adsorption temp., gaseous Ar contg. N2 is introduced again. Said operations are successively repeated.

Title: Clothes-drying machine
Inventor: OGOSHI KENICHI
IPC: D06F58/28
Filed: 1989-04-14
Abstract: PURPOSE:To reduce noise and to make a clothes-drying machine suitable for night operation by lowering the revolving speed of an air blowing fan when a drying end time is reversed and set and the drying machine is operated. CONSTITUTION:After the reservation is started, the operation is on standby in an operation stop state until the operation starting time of a first term drying operation process. When the operation starting time comes, drying operation is executed. According to information from a drying detection circuit 30, the operation is finished in a state that prescribed humidity is remained in an object to be dried. During this process, an operating time required for a later term drying process is forecasted according to the information from the drying detection circuit 30 or the like. In the later term drying operation process, the drying operation is executed for a time, which goes back from a finish reserving time only for a time forecasted during the earlier term drying operation process. When it is judged according to the information from the drying detection circuit 30 that the object to be dried is dried, the operation is finished. In the case of such a method, since the drying machine is operated with lowering the revolving speed of a motor 5, the revolving speed of double fans 8 is lowered and the noise can be reduced. Accordingly, even when the drying machine is used at night, it is relieved of disturbing quiet sleep.

Title: Air flow rate measuring device
Inventor: YOGO TAKAYUKI
IPC: F02D35/00
Filed: 1995-04-19
Abstract: PURPOSE: To hold down a pressure loss, and reduce upstream drift influence by separately making the upstream side of an auxiliary air passage and the downstream side including the auxiliary air passage, and changing the fitting angle in case of connection. CONSTITUTION: A main air passage 1 and an auxiliary air passage 2 are provided side by side in the upstream side 3 of the passage 2 and the downstream side including the passage 2, and an inflow air quantity is measured by an electric current flowing through a heating resistor 5 disposed in the passage 2. As the resistor 5 allows feeble current to flow according to an air flow rate, it is necessary to reduce an upstream drift influence. Especially, as the passage 2 is positioned with eccentricity from the center of the passage 1, it is easily influenced by the drift of the upstream side 3 according to the change of installation direction of an air cleaner installed on the upstream.  Accordingly, the upstream side 3 of the passage 2 and the downstream side 4 including the passage 2 are separately manufactured, and if the fitting angle is changed according to the installation direction of the air cleaner in case of connection, the influence of the upstream drift can be reduced and the air flow rate detecting accuracy can be improved.

Title: Image forming device
Inventor: SEKIGUCHI ATSUSHI
IPC: G03G15/00
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To improve the reproducibility of an image density gradation to the PWM of an image to be formed. SOLUTION: A single fundamental color is set for input image data consisting of fundamental colors such as yellow, magenta, cyan and black (S21) and is divided into blocks of specified size in a main scan direction (S22). In addition, an average value is sought for each of the density values of these blocks (S23), and the density values are sorted in terms of level by the magnitude of the average value (S24). When it comes to an intermediate density, the gradation is converted using a rearrangement matrix with a maximum weighted position arranged at a different position per color (S25). Further, of a low density area and a high density area, the gradation is changed using the rearrangement matrix with the changed weighted position (S26, S27). This process is repeated in the entire auxiliary scan direction (S28) for all the fundamental colors (S30).
