Title: Controller for controlling operation of device for ventilating space under floor
Inventor: ISHIZUKA ICHIROU
IPC: F24F7/007
Filed: 1983-04-01
Abstract: PURPOSE:To purge the humidity in a space under the floor and further to operate a ventilating device intermittently so as to shorten the total operating time and reduce the operation cost by automatically operating the ventilating device by the difference between the humidity in the space under the floor and the humidity in the external air. CONSTITUTION:Sensing parts 6 and 7 for sensing the humidity in the space under the floor and the humidity in the external air, are installed in a space under the floor and a space under the eaves. When the difference between the humidity in the space under the floor and the humidity of the external air becomes HON, the contact 11 is closed, power is supplied to a motor 10, and the ventilating device 1 starts its operation, the humidity under the floor being discharged out of the hourse and the humidity in the space under the floor being gradually decreased. When the difference between the humidity in the space under the floor and the humidity in the external air becomes HOFF, the contact 11 is opened, power supply to the motor 10 is stopped and the operation of the ventilating device 1 is also stopped. Thereafter, the humidity from the ground surface is gradually accumulated. When the difference between the acuumulated humidity and the humidity in the external air becomes HON, the operation of the ventilating device 1 is similarly resumed. As a result, the ventilating device 1 carries out intermittent operations. Hence, the operation time may be shortened, and further, the humidity under the floor may be accurately discharged without requiring labor.

Title: Method of driving array-type semiconductor laser device
Inventor: YAMANAKA YUTAKA
IPC: H01S5/062
Filed: 1988-03-14
Abstract: PURPOSE:To decrease the effect of adjacent light sources on each other by a method wherein light sources are driven by a periodically modulated current whose frequency is higher than a specified value, where a threshold current which starts generating an oscillation is between the maximum and the minimum amplitude of the modulated current. CONSTITUTION:In a usual semiconductor laser, the optical output is nearly proportional to the variation of a drive current when the drive current is equal to or larger than a threshold current Ith. Therefore, provided that a drive direct current required for obtaining an average optical output P denotes (Ip+Ith), the average optical output of a laser driven by a square pulse of 50% duty whose minimum and maximum value are Ith and (2XIp+Ith) respectively is also equal to P. If the drive current is less than the threshold current Ith, the laser does not start oscillating, so that the optical output is the same even if the minimum value of a drive pulse is less than Ith. On the other hand, if the minimum value is made smaller than Ith, the average drive current becomes smaller than (Ip+Ith). Therefore, the rise of temperature becomes small. If the period of a pulse is smaller than a time constant of the heat interference, the rise of temperature can be considered to be nearly the same as a direct current drive, so that it is sufficiently effective if the period of a pulse is 1kHz or more.

Title: Automatic phase control circuit
Inventor: NAKAKAWARA KIYOUICHI
IPC: H03D3/00
Filed: 1978-05-17
Abstract: PURPOSE: To make it possible to widen a follow-up range without increasing the jitters of a demodulation carrier, by controlling pulse insertion for control and the number of times of erasing corresponding to a phase error.  
     CONSTITUTION: The output of absolute-value comparator circuit 4 is supplied to sample holding circuit 101, where it is sampled by sampling pulse S and then held. The output of this sample holding circuit 101 is rectified by full-wave rectifier circuit 102 and the obtained voltage is regarded as error voltage F. Sampling pulses S, on the other hand, is integrated by integrating circuit 103 into integral output E. These both are compared each other by voltage comparator circuit 104; when E is greater than F, ccomparison output G is inverted. Next, AND circuit 106 calculates the logical sum of comparison output G, sampling pulse S and the 2nd higher clock 105. This output, namely, control pulse J is applied to pulse insertion-deletion circuit 62, which inserts or deletes a pulse into or from the 1st higher clock 7 at every time when one control pulse J is inputted.

Title: Boring tool
Inventor: NAKAMURA SHINICHI
IPC: B23B51/00
Filed: 1987-03-13
Abstract: PURPOSE:To improve the dischargeability of a core by forming at least a part of the section, which is extended along the rearward in the rotational direction from the contact of an inscribed circle of the fellow wall faces, in inclination toward peripheral side to the tangent of this inscribed circle, among the wall faces which face each other with an axis of the opening between. CONSTITUTION:When cut processing is started, the cutting is realized by an inside edge 13a and a cut blade 13 on the peripheral side. On the other hand, the core grows up in the central part of the material to be cut and when it grows up to some degree, it will be twisted off by the cut resistance and discharged from an opening 14. Then the space between the fellow wall faces 16 of the opening 14 is gradually widened according to the tangent 1 direction from the contact P deg. of this inscribed circle. As a result, the free degree of the core becomes large and the wall face 16 becomes hard to be abrased by the core, whereby the core can be discharged favorably. Accordingly, there never occurs such a case that the wall face 16 should be abnormally abrased or chipped.

Title: Pattern formation and treatment system
Inventor: TAKASE KAZUHIKO
IPC: H01L21/3065
Filed: 1998-03-10

The produced water attains and attaches to an oxide film 22 and hydrofluoric acid solution of high concentration is produced as hydrofluoric acid constituting atmosphere dissolves. Therefore, an etching rate of the oxide film 22 increases in a region A alone in contact with hydrofluoric acid solution 25, a pattern is formed to the oxide film 22 and the width of a pattern is about 200Å. Therefore, a fine pattern can be formed to an oxide film in a short time while keeping a surface of a board and various formed films, etc., clean without increasing the number of processes.
