Title: Method for base treatment of powdery polyethylene lining
Inventor: HASEGAWA SHIGEO
IPC: B05D7/14
Filed: 1992-04-27
Abstract: PURPOSE:To enable formation of excellent polyethylene lining even in a high temp. environment by blasting or pickling the surface of a material to be lined, heating to form a film essentially comprising Fe3O4, then bringing the material into contact with a specified chromate soln., and then drying. CONSTITUTION:The lining method of powdery polyethylene includes the following process. A material to be lined consisting of carbon steel is preheated at temp. higher than the melting point of the polyethylene powder, to which powdery polyethylene is supplied. The powder is molten by the heat of the material to be lined so as to form a continuous polyethylene film on the surface of the material. As for the base treatment of the material to be lined, the surface of the material is blasted or pickled and the surface is heated at 300-500 deg.C to form a film essentially comprising Fe3O4. Then the surface is brought into contact with a chromate soln. of pH 4.5 to 6.0 containing 0.005-0.05wt.% CrO3 concn., and then dried.

Title: Tuner demodulation unit
Inventor: MOGI MINORU
IPC: H04B1/08
Filed: 1989-04-28
Abstract: PURPOSE:To obtain a tuner demodulation unit with simple shield structure and wide degree of freedom of design by applying high frequency shield to each function table block with ground structure. CONSTITUTION:An RF input block RF input block 1, a filter block 2, a frequency conversion block 3, a channel selection block 4 and an IF demodulation block 5 of the unit are isolated in terms of high frequency with shield plates 10-12. That is, the RF input section is isolated from the next and succeeding circuit blocks with the shield plates 10, 11 to prevent the leakage of the signal generated in the inside of the circuit such as a local oscillation signal from the RF input terminal 6. Furthermore, the leakage of the signal generated by the channel selection block 4 to the output of the IF demodulation block 5 is prevented by isolating the channel selection block 4 and the IF demodulation block 5 with the shield plate 12. Thus, the tuner demodulation unit with a wide degree of design freedom and simple shield structure is obtained.

Title: Hydraulic control device for driving hydraulic actuator
Inventor: MIYAURA HIDEOMI
IPC: F15B11/00
Filed: 1994-04-22
Abstract: PURPOSE:To prevent a shock generated at a hydraulic actuator at the starting time or at an acceleration time following the starting time, by providing a low pressure relief valve and a throttle valve in series, at a branch passage to connect a pump oil passage to a tank. CONSTITUTION:At a branch passage 7 branched from a pump oil passage 3a and connected to a tank 4, a low pressure relief valve 8 and a throttle valve 9 are provided in series. Even though the throttling of a carry over oil passage 1a is carried out preceedingly in the converting process at the starting time or at the acceleration time following the starting time of a hydraulic change- over valve 1, and the hydraulic pressure of the pump oil passage is going to rise higher more than necessary, the pressure rise is relaxed by the flowing-out of the operating oil to the tank 4 passing through the throttle valve 9 and the low pressure relief valve 8 at the branch passage 7. Consequently, the oil pressure of the pump oil passage 3a in the change-over process is relaxed compared with the conventional system, and the shock of the hydraulic actuator 2 at the starting time and at the following acceleration time can be reduced as the portion of the relaxation.

IPC: H05K3/34
Filed: 1988-04-30
Abstract: PURPOSE:To enable the masking with a single sticking operation easily by a method wherein a masking seal whose shape is similar to that of the arrangement of lead pins of an after mounting component is used to mask pin holes of the after mounting component together. CONSTITUTION:A masking seal 18, whose shape is equal to that of the arrangement of lead pins 14 of a component 12 inserted into pin holes 16 which are to be masked, is previously formed by frame-cutting a masking tape. The pin holes 16, into which the pins 14 of the component 12 are to be inserted, are covered with a single masking seal 18. Therefore, an operator separates the masking seal 18 from the masking tape and sticks it on a masked part. By these processes, parts required to be masked can be masked with a piece of masking seal without cutting a mask tape into pieces for each hole and sticking them, so that holes scattering in a wide range can be easily masked.
