Title: Rotating speed controller for ac motor
Inventor: YAMADA TOSHIYUKI
IPC: H02P27/02
Filed: 1987-03-06
Abstract: PURPOSE:To control the rotating speed of the title motor stably, by changing the width of a gate pulse in accordance with a control phase angle. CONSTITUTION:A control micro-computer 9 is equipped with a speed control means 10, a phase angle discriminating means 11 and a pulse width control means 12. The speed control means 10 detects an actual number of rotattion based on a pulse signal inputted from a Hall element 8 while the detected actual number of rotation is compared with the objective number of rotation, specified in accordance with an air-conditioning condition, to reduce the control phase angle when the actual number of rotation is smaller than the objective number of rotation. On the other hand, when the actual number of rotation is larger than the objective number of rotation, a phase angle from a zero cross is controlled by impressing gate pulses on respective triod AC switches so as to increase the control phase angle.

Title: Ultrasonic type anti-carthief apparatus
Inventor: FUKUSHIMA HIROSHI
IPC: G01S15/04
Filed: 1988-03-07
Abstract: PURPOSE:To enable positive detection of a slight opening of a door or a window glass for a vehicle, by storing an inclination of a reflected wave in each time zone to make a judgement in comparison with a new reflected wave pattern received at a fixed interval per time zone. CONSTITUTION:A burst-like transmission signal coming from a transmitting circuit 3 as controlled with a reference signal generator 2 is sent to an ultrasonic microphone 1a for transmission to generate a burst-like ultrasonic signal. The ultrasonic wave as reflected back from a seat, window glass and the like in a car room is converted into an electrical signal with an ultrasonic microphone 1b for reception. Then, after amplified 4, the electrical signal is detected through a detection circuit 5 and a level judgement on a pulse-like waveform corresponding to a pulse-like envelope line is performed in a time sharing manner with a sampling/holding circuit 6 in terms of a time zone specified by a reference signal generator 2 and the electrical signal is converted into digital from analog. Inclination of waveforms is compared between the ultrasonic signal and a new reflected wave received at a fixed interval. The reflected wave is passed only when the inclination thereof coincide with each other. Then, the number of the reflected waves is divided by a time shared number of those of non-coincidence to calculate a ratio. When the ratio exceeds a fixed value, an alarm is outputted.

Title: Gas turbine combustor
Inventor: SAKAMOTO YUUJIROU
IPC: F23R3/12
Filed: 1978-05-02
Abstract: PURPOSE: To conduct a high-load combustion with compacter structure by arranging a swirler in the top end of the gap between a housing inner wall and a liner structure outer wall.  
     CONSTITUTION: A swirler 8 for introducing primary air into a combustion chamber formed by a liner structure 2 is displaced outward from the center axis of the structure 2 so that the primary air is provided with swirling effect in a lower-speed zone. As the primary air is injected into the combustion chamber through an air feed port 3 where obstacles such as a swirler vane are not present, pressure loss is largely reduced. In addition, the absence of the swirler in the port 3 reduces the aperture of the port 3, reduces the diameter of a combustion flame, enables a high-load combustion, and makes the structure 2 compacter.

After the gas ejection is over, ion beam 8 is irradiated in a region where the dummy foreign matters are to be formed. Then, the ion beam 8-irradiated region is heated on the wafer substrate 6 and the tungsten carbide is pyrolytically decomposed. The tungsten is then deposited on the irradiation region. For example, one dummy foreign matter 2 is formed thereon.
