Title: Assembly method for magnetic fluid seal device
Inventor: MATSUNAGA SHIGEKI
IPC: F16J15/43
Filed: 1988-08-31
Abstract: PURPOSE:To extend the period of a seal life by previously providing a recessed part of narrow width along annular pole pieces in an annular groove and injecting magnetic fluid into this recessed part. CONSTITUTION:First before a seal member C1 is fitted to a shaft 2, magnetic fluid 7b is injected into an annular groove (m) of the seal member C1. Then the magnetic fluid 7b is firmly held into a recessed part m1 by a strong magnetic field in the recessed part m1 and by surface tension intensified by forming the recessed part m1. Under this condition of the seal member C1, when it is fitted to the shaft 2, the magnetic fluid 7b of the recessed part m1 begins slowly spreading by attracting force based on surface leakage quality of pole pieces 4, 5, and the fluid, when it is placed under an influence of a magnetic field formed by a seal gap (g), is moved so as to be attracted to this magnetic field, then the seal gap (g) is filled with the fluid with the lapse of time.

Title: Production of electrophotographic sensitive body
Inventor: TANAKA TAKESHI
IPC: G03G5/05
Filed: 1985-09-27
Abstract: PURPOSE:To improve the coating efficiency of a photosensitive coating and to obtain uniform film thickness with high productivity by setting up the boiling point of a dispersed medium of a photosensitive coating to 35-179 deg.C. CONSTITUTION:At the spraying of the photosensitive coating to a cylindrical board surface, sprayed coating drops can be directly adhered to the surface of the base board in the maximum expanding angle thetae (effective angle) area. Drops existing outside the effective angle area even if included in the spraying cone and drops scattered to the outside of the effective angle area are dried as scattered grains and a part of them is included again in the spraying flow or adhered to the surface of the photosensitive body through dry air in a dry hood, so that grain-like surface may be generated and the coating efficiency is reduced in other part as spraying loss. Said trouble can be prevented by setting up the boiling point of the dispersed medium of the coating to 35-170 deg.C. When the boiling point is <=35 deg.C, the dispersed medium is too quickly vaporized, and in case of >=170 deg.C, the drying speed is delayed and productivity is reduced.

Abstract: PURPOSE:To realize an optional frequency shifter by using an acoustooptic medium provided with transducers consisting of two channels independent of each other and introducing an output light to an optical fiber by a lens to obtain one optical beam. CONSTITUTION:An acoustooptic medium 1 is provided with transducers 2a and 2b having electrodes of two channels (CH) independent of each other. When electrical signals whose frequencies and amplitudes are set are inputted to these two CHs from high frequency signal sources 3a and 3b, they go as ultrasonic signals in the medium 1.

When the frequency of the input light is denoted as F0 and driving frequencies of two CHs are denoted as fa and fb, frequencies of diffracted lights 6a and 6b are F0+fa and F0+fb by the Doppler effect. These lights interfere when going in the optical fiber 5a, and a beat light is obtained as the optical output 7a, and the diffracted light and non-diffracted light can be separated from each other, and the device is made small-sized and low-cost.

Title: Cooling apparatus
Inventor: ADACHI YUTA
IPC: H01L21/66
Filed: 1988-08-31
Abstract: PURPOSE:To simultaneously test semiconductor elements different in power consumption in the same burn-in tank by providing a contact control means for controlling the contact of a heating unit and a radiation means by the expansion and contraction due to the temperature of the heating unit. CONSTITUTION:A semiconductor 1 is fitted to the socket of a burn-in tank to close the same. The contact control part 2 of a cooling apparatus is brought into contact with the semiconductor 1 and absorbs the heat generated by the power consumption of the semiconductor 1 to a certain degree. When the quantity of heat generatecd by the semiconductor (the power consumption of the semiconductor) at that time is large, the control part 2 expands to widen the contact surface between a radiation part 5 and the control part 2. When the quantity of heat generated by the semiconductor 1 is relatively little, the expansion of the contact control part 2 is small. The quantity of heat transmitted to the radiation part 5 from the semiconductor 1 through the control part 2 depends on the power consumption of the semiconductor to become junction temperature relatively free from temp. difference.

Title: Evaluation test for electrodeposited part
Inventor: NAGURA YASUMI
IPC: G01N19/04
Filed: 1991-08-28
Abstract: PURPOSE:To evaluate the bonding strength of the part of electrodeposition based on the pressure, when leakage occurs from the electrodeposition part or the diameter of a through hole, through which leakage occurs, by applying inner pressure or external pressure on a container wherein electrodeposition is performed so as to seal the through hole which is machined beforehand. CONSTITUTION:A through hole 12 having the diameter of about 1mm is provided in a testing container 11, which has the tube shape with the diameter of several tens of mm and can apply inner pressure. Electrodeposition 15 is performed on the through hole 12 from the outer surface of the container 11. Internal pressure is applied on the container 11 through a pressure applying hole 14. At this time, the pressure is gradually increased from the low pressure. The pressure when leakage occurs is made to be the limit pressure. This method is suitable for evaluating the limit pressure of the electrodeposition part 15 in consideration of the case wherein a minute circular through hole is present in the object of electrodeposition. The diameter is set at 1mm in consideration of the facts that the diameter of the through hole is small and easy fabrication of the testing container 11 based on the property of the electrodeposition. With this method, the bonding strength of the electrodeposition part and airtightness can be simply evaluated.
