Title: High frequency power module and its manufacture
Inventor: MAEDA MASAHIRO
IPC: H05K7/20
Filed: 1996-04-18
Abstract: PURPOSE: To provide a high frequency power module which is excellent in radiation effect and has earthquake-proof property, in a high frequency multistage power amplifying circuit. CONSTITUTION: A printed board 6 on which solder chip components and power semiconductors are mounted is fixed to a radiating plate whose surface is plated with solder, by using solder or the like. A second stage semiconductor 7 necessitating heat dissipation is directly fixed, by using solder or the like, to the radiating plate 1 whose surface is plated with solder, through a hole formed in a printed board 6. As compared with the conventional nickel-plated radiating plate, the solderability of the plating plate 1 whose surface is plated with solder is superior, so that the fixing situation of the second stage semiconductor 7 is remarkably improved. Thereby the heat conduction efficiency is improved, the heating of the semiconductor 7 is restrained, and the decrease of output power can be avoided.

IPC: H05H6/00
Filed: 1989-04-18
Abstract: PURPOSE: To obtain a neutron generator including a target subjected to a hydrogen ion beam in which the lifetime of target is prolonged by composing the target of a laminate of identical layers isolated by a diffusion blocking layer. CONSTITUTION: In this neutron generator for generating neutrons by striking an ion beam generated from an ion source 4 against a target 16, the target 16 is composed of a laminate. More specifically, a plurality of titanium layers 19, 21, 23, 25, 27 having high hydrogen absorption coefficient are laminated while sandwiching hydrogen diffusion blocking layers 20, 22, 24, 26 on a molybdenum substrate 18 forming a support layer. Thickness of the titanium layer is set equal to the permeation depth of ion. This structure prolongs the lifetime of target by a factor equal to a multiple of the number of laminated layers as compared with a case employing only a single layer.

IPC: C02F1/68
Filed: 1980-07-15
Abstract: PURPOSE: To prevent scales due to sea water by providing a sea-water decarboxylation device with an acid injection-amount varying mechanism and an air-amount varying mechanism successively, and by controlling the pH of the sea water after decarboxylation.  
     CONSTITUTION: Raw sea water W 1  is introduced from an introduction line to a mixing tank M, where its pH is adjusted to be sprayed from the upper part of a decarboxylation tower T 2  while air is blown from the tower bottom, thus reducing total carbonic acid. The treated sea water W 2  from the tower T 2  is measured by a residual alkali measuring indicator ALKI in terms of residual alkalinity, and when its measured value is held at an indication value, the control signal of a pH indicating controller pHIC is transferred to a wind-amount regulating mechanism C 2  to vary the opening degree of a damper D so that a prescribed PHK is obtained. If the residual alkalinity varies, the control signal of the pH indicating controller PHIC is transferred to an acid-indication amount regulating mechanism C 1 , which is changed over to the wind-amount regulating mechanism C 2  again after the injection amount of acid reaches prescribed residual alkalinity.

Filed: 1995-04-21
Abstract: PURPOSE: To suppress chattering vibration of a wiper blade by detecting the chattering vibration, heightening the revolving speed of a wiper motor in accordance with the size of the detected value, and thereby heightening the operating speed of the wiper blade. CONSTITUTION: The vibration of a wiper blade in operation is detected by an acceleration sensor 6, and the result is transmitted to a judging part 9 of a motor control means T1. The detected value is compared with the reference value by a comparator 12 in the judging part 9, and if the detected value is greater than the reference value, judgement is passed that a chattering vibration has occurred. In this case, a relay switch RS1 is turned on so that current is fed to an energizing coil 101, and its normally closed contact 102 is opened while normally open contact 103 is closed. This changes over the output of a wiper motor 1 to the high output side, and current is fed to a plurality of resistances R1-R3 so that the revolving speed of the wiper motor 1 is one step heightened from the value in the low speed operation.
