Patent JP-H01314158-A (JP)
Title: Heat exchanger, manufacture thereof and surface treatment agent thereof
Inventor: KOGA YOSHIAKI
IPC: G03B27/54
Filed: 1988-06-15
Abstract: PURPOSE:To obtain a heat exchanger suppressed in the propagation of bacteria, prevented from the generation of an offensive smell and enhanced in surface hydrophilicity by forming a silicon type film having an antibacterial agent dispersed thereon to the surface of the heat exchanger. CONSTITUTION:A heat exchanger is constituted by forming a chromate film 2 to the surface of a base material 1 composed of aluminum or an alloy thereof and further forming a silicon type film H having an antibacterial agent 4 dispersed therein to said film 2. The core part thus completed in the pretreatment process is immersed in a surface treatment agent being a silicic acid or silicate solution having the antibacterial agent dispersed and compounded therein. Since the propagation of bacteria, fungi and yeast is suppressed when a formed silicon type film is an alkali silicate film, as silicic acid or silicate to be used, sodium silicate, potassium silicate and water glass are especially desired. After the surface treatment agent is uniformly adhered to the surface of the core part, heating/drying treatment is applied to the coated core part to remove a solvent and silicic acid or silicate is gelled to make it possible to form the silicon type film having the antibacterial agent 4 dispersed and compounded therein. As a result, the heat exchanger capable of suppressing the progration of bacteria and capable of keeping hydrophilic effect for a long period of time is obtained.

Title: Resin sealed semiconductor device
Inventor: AKIYAMA TATSUHIKO
IPC: H01L23/28
Filed: 1987-06-10
Abstract: PURPOSE:To prevent the moisture absorption and moisture permeation from the sealing resin surface into the inside by integrally burying non-moisture permeable or difficultly moisture permeable material layers opposite to both sides of a semiconductor element in the sealing resin. CONSTITUTION:There are provided non-moisture permeable material layers 7, 7 of thin metallic plates for instance, which are integrally buried and similarly sealed within a sealing resin 6 so as to be opposed to both sides of a semiconductor element 2. Accordingly, the moisture absorbed or transmitted from the surface of the sealing resin 6 is shielded by the buried non-moisture permeable material layers 7, 7. With this, the penetration into the inside or into the surface part of the semiconductor element 2 is prohibited, or the penetration path becomes longer, whereby the penetration can sufficiently be delayed in time.

Title: High voltage dc source
Inventor: BURATSUDORII ROBAATO GAN
IPC: H02M7/06
Filed: 1988-06-15
Abstract: PURPOSE: To produce a high DC voltage inexpensively by providing a resonance circuit means connected with a flyback choke, a switch and a rectifier means. CONSTITUTION: A power supply 21 for a traveling-wave tube 13 converts the DC voltage between terminals 22, 23 from an AC-DC converter 24 into a high frequency waveform which is then converted through a voltage multiplier 37 into a high DC voltage. High frequency conversion of the DC voltage is performed through a network 31 comprising an FET switch 32, a series resonance circuit of an inductor 34 and capacitors 35, 36 and a flyback choke 63 wherein an oscillator 64 is controlled with a voltage passed through a voltage divider 68 and the FET switch 32 is driven. Amplitude of a current hump in a resonance circuit 33 depends on the on state operating frequency of the switch 32 and controlled by the quantity of energy stored in the flyback choke 63. Consequently, the amplitude of current in the resonance circuit decreases as the on state time of the switch 32 is shortened.

Abstract: PURPOSE:To obtain the minute glass layer, in depositing glass powder on the specified surface of the semiconductor element by an electrophoresis method and burning, by adding a beta-unsaturated compound having an electron-withdrawing group at the alpha position into the glass-powder dispersed liquid. CONSTITUTION:Yttrium nitrate and magnesium nitrate are added into the glass dispersed liquid wherein zinc borate glass powder is dispersed in isopropyl alchol.

Title: Method and device for regulating concentration in underwater granuator
Inventor: NAKAMURA YOUICHI
IPC: B01J2/10
Filed: 1981-09-18
Abstract: PURPOSE:To obtain granulated coal of good quality efficiently by performing the entire process of granulation through plural granulating tanks and treating liquid to be treated in such a way that the concns. thereof increase when moving the liquid from a tank to a tank. CONSTITUTION:The liquid 10 to be treated in the 1st granulating tank 2 overflows into a trough 18 by as much as the flow rate at which said liquid flows into said tank from the side of a valve regulating tank. Water 25 enters the inside of a fluid receiving tank 21 through screen meshes 20. Granulated coal 14a remains in the trough 18. The granulated coal in the trough 18 is fed into the 2nd granulating tank 3 on account of its inclination. since the flow rate of the water 25 discharged from the tank 21 is smaller than the flow rate at which said water enters the tank 21, the water 25 in the tank 21 overflows finally from a fluid overflowing outlet 22 into the tank 3. Thus the water 25 is again mixed with the coal 14a, and the liquid 10 having a concn. higher than the concn. in the tank 2 is obtained.

Abstract: PURPOSE:To improve oil film pressure borne by a segment and largely prolong the life of a bearing by setting a place for installing a segment positioned at the lowermost part within a definite range. CONSTITUTION:When an interval between a rotary shaft 1 in a stationary state and segment 2 positioned at the lowermost part and also an interval between said rotary shaft 1 not in rotary motion and other segment 3, 7 adjacent to the segment 2 positioned at the lowermost part are defined as L1 and L2 respectively, the segment 2 positioned at the lowermost part is so installed as to satisfy the relation 2>=L1/L2>=1.25 between the intervals L1 and L2. Thus, oil film pressure P2 borne by a segment 2a is about same as oil film pressure P3, P7 borne by other adjacent sections 3a, 7a respectively. The oil film pressures borne by those segments are not only equalized but also reduced in its peak value in comparison with that of the conventional structure. As a result, the total bearing capacity is increased.
