Title: Self-aligning type clutch release bearing unit
Inventor: NIKI MOTOHARU
IPC: F16C23/08
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To control an initial contact angle in a highly accurate manner. SOLUTION: Supposing that an inernal radial clearance Δr (=Δri+Δre: radial quantity) is fixed, a contact angle α is also fixed by COSα=1-[Δr/(ri+ re-Da)]. A ball bearing of this self-aligning type clutch release bearing unit is elastically supported on a sleeve free of radial movements, and since both inner and outer rings are not fitted in any other members, there is no variation in an internal radial clearance Δr, and the contact angle α being fixed like that comes to an initial contact angle. Therefore, this initial contact angle αis accurately controllable, owing to this internal radial clearance Δr.

Title: Capacity control system for ultrasonic humidifier
Inventor: YAMAMOTO YASUO
IPC: F24F11/02
Filed: 1987-04-16
Abstract: PURPOSE:To maintain the efficiency of a humidifier at the maximum by a method wherein the repeated period of ON-OFF is carried out in a range of 1-10 seconds and humidifying capacity is controlled at the rate of ON time. CONSTITUTION:An ultrasonic humidifier is controlled in its humidifying capacity at the rate of ON time in repeated period of ON-OFF by a switch. This repeated period ranges 1 to 10 seconds. When this repeated period is under 1 sec., atomization efficiency is not made sufficient and the efficiency is reduced. Even when the repeated period is 10 sec., or more, the efficiency can be kept maximum; however, when the period is extended like this, the operation approaches an ordinary interrupted one and this method is not considered to be practical as a capacity control method. As a result, by carrying out the repeated period in the range mentioned above sufficiently high efficiency can be maintained and the practical humidifying capacity can be controlled.

Title: Digital magnetic recorder/reproducer
Inventor: NAKAGAWA SHIYOUZOU
IPC: G11B20/10
Filed: 1978-08-01
Abstract: PURPOSE: To ensure a high-quality recording/reproducing for the code signal by identifying once the reproduced signal waveform in the mode of the code signal different from the recording time and then restoring the signal waveform to the mode of the original code signal.  
     CONSTITUTION: The desired binary code signal A is formed into binary code signal B through modulo two converter 1 and then recorded. With reproduction of recorded signal B, the signal waveform is differentiated through reproduction magnetic head 7 and furthermore reproduced signal waveform C the higher band component of which is attenuated can be obtained. Signal C is then converted into ternary code signal D through equalizer 9. Signal D is then led to differential amplifier 10, and then the differential signal between the 0 level and the signal level at each bit position to be compared with the threshold level signal at comparators 12 and 13. Thus the restoration conversion is given to signal A. As a result, an accurat identification is possible for the reproduced signal, and thus the digital code signal can be reproduced with an extremely small code error rate.

Filed: 1986-04-22
Abstract: PURPOSE:To raise the reading resolution of a quickly moving object and to reduce power consumption by intermittently lighting the 1st light source according to a previously detected synchronizing signal and reading the mark of the 1st light receiving element. CONSTITUTION:The titled device is provided with a photointerrupter 10 having an LED 10A and a phototransistor Tr10B. An LED11, an image sensor 12 and an optical lens 13 are provided the prescribed distance from said photointerrupter 10. The titled device has such a structure that the object 14 with marks such as bar codes moved in the direction of an arrow of the optical path between the LED10A and the Tr10B and that between the LED 11 and the lens 13. As the object 14 moves quickly, the TR10A detects the mark 14A, and therefore the synchronizing signal when the mark enters the visible field of the sensor 12 is obtained beforehand. When the mark 14A moves to enter the visible field of the sensor 12, the LED 11 is intermittently lighted according to the synchronizing signal, and the sensor 12 reads the mark 14A. If the lighting time width is shortened, reading at high resolution can be possible.

Abstract: PURPOSE:To suppress the growth of a contact spike for the enhancement of reliability by a method wherein a cutaway is provided, at a part of the circumference of a contact electrode section of a wiring conductor connected to a semiconductor substrate, for the separation of the wiring conductor main body from the contact electrode section. CONSTITUTION:At a part of the circumference of a contact electrode section 14 of a wiring conductor 12 connected to a semiconductor substrate, a cutaway 15 is provided for the separation from each other of the main body 12a of the wiring conductor 12 and the contact electrode section 14. In this design, a contact spike that may be produced in the contact electrode section 14 will be prevented from further growth because the supply of spike-enlarging aluminum from the wiring conductor 12 is suppressed owing to the cutaway 15. With the growth of the contact spike being thus impeded, aluminum will be stopped from extending deeper than a diffusion region to penetrate through the P-N junction of a semiconductor device, protecting the semiconductor device from reduced reliability.
