Title: Enclosed type motor compressor
Inventor: ONO TAKESHI
IPC: F04B39/00
Filed: 1987-06-22
Abstract: PURPOSE: To damp the pressure pulsation due to a suction reed and reduce the noise or vibration by providing a low-pressure chamber near the compression chamber of a cylinder and communicating a suction muffler and the low- temperature chamber with a communicating hole provided near the suction port of a valve plate.  
     CONSTITUTION: A cylinder 18 forming a compression chamber is blocked with a valve plate 14. A suction port 15 is provided on the valve plate 14, and a suction muffler 11 is communicated to the cylinder 18 via this suction port 15. The cylinder 18 forms a recess opened to the valve plate 14 side and forms a low-pressure chamber 18a together with the valve plate 14 in this constitution. The low-pressure chamber 18a is communicated to the suction hole 13 of a cylinder head 5 and the communication section 12 of the suction muffler 11 via a communicating hole 20. The pressure pulsation due to the movement of a suction reed 17 is thereby damped with the low-pressure chamber 18a, and the movement of the suction reed 17 is smoothed.

Title: Positive temperature coefficient thermistor
Inventor: NAGAO YOSHITAKA
IPC: H01C7/02
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To improve the flash resistance and Pmax of a positive temperature coefficient thermistor, by making part of the peripheral edge sections of the main surfaces of a ceramic body having a positive temperature characteristic of resistance thicker than the central part of the ceramic body, and forming electrodes on both main surfaces of the ceramic body. SOLUTION: A positive temperature coefficient thermistor 1 is obtained by respectively forming ohmic electrodes 3 and 4 on both main surfaces of a positive temperature coefficient thermistor element 2. The element 2 is composed of a discoid ceramic body which is formed by molding and sintering a ceramic material for positive temperature coefficient thermistor containing barium titanate as a main component, and has a positive temperature characteristic of resistance. Then, projecting sections 5, 7, and 8 which are thicker than the central part of the ceramic body are partially formed in the different peripheral edge sections of both main surfaces of the ceramic body. Therefore, the flash resistance of the thermistor 1' is remarkably improved, and the distance between the electrodes 3 and 4 is increased without lowering the resistivity of the thermistor 1.

Title: Steering control method of car
Inventor: KONDOU YOUJIROU
IPC: G05D1/02
Filed: 1983-08-25
Abstract: PURPOSE:To improve run characteristics by controlling continuously steering operation on the basis of the position deviation from a guide and the number of revolutions of wheels. CONSTITUTION:A car body which is steered automatically along a guide 3 is provided with two sensors which detect the guide 3 at points P and Q in front of the car body and the wheels at points A and B. The motors for the wheels are driven independently on the basis of the detection results of those sensors to control the steering of the car body. In this case, the control over the steering is performed in two stages, and when the left-hand sensor P turns off by deviating from the guide, the speed V1 of the right-hand driving wheel is reduced to start steering the body to right. Then, the left-hand sensor P moves onto the guide 3, so the body begins to be steered back, the acceleration/deceleration speed is reduced when the speeds to the driving wheels on both sides becomes equal to each other, and this operation is repeated. Consequently, the steering- back operation is topped when the position deviation attains to maximum and smooth steering-back operation for returning to the guide 3 is started.

CONSTITUTION:A recess 2 is formed in a silicon substrate 1 by stop etching, and then a metallic film 3 is deposited, and next screen printing is performed, and mask material 6 is dropped sufficiently on a screen 5. And by shifting a squugee 7 along the upper face of the screen 5, the film of the mask material 6 is printed on the surface of a substrate 1, and the mask material 6 does not adhere to the inner face of the recess 2. Hereafter, when etching is performed, a metallic film 3 inside the recess 2 is removed completely, and neither pin hole nor side etch occurs at the metallic film 3 on the surface of the substrate 1. Hereby, the film at the inner face of the recess can be removed completely, and the film on the surface of the semiconductor board 1 other than the recess 2 can be maintained as it stands in the favorable condition.
