Title: Corrosion resistant protector
Inventor: ABE HIROSHI
IPC: C23F15/00
Filed: 1977-10-07
Abstract: PURPOSE:To enhance the corrosion resistance of a corrosion resistance protector made of stainless steel or the like by irradiating the protector surface with laser beam. CONSTITUTION:The protective tube of a thermocouple which comes in contact with fused sodium in a fast breeder is made of stainless steel. The surface of the stainless steel tube is irradiated with laser beam to enhance the corrosion resistance to sodium as well as to make the surface amorphous and harden it. The protective tubes of a sheath heater and a thermocouple used to fused aluminum are convered with Mo by spraying to avoil alloying with aluminum. It sometimes happens that pinholes are formed in the sprayed Mo layer, so the layer is irradiated with laser beam to convert the layer into uniform one with no pinhole, thereby enhancing the corrosion resistance to aluminum.

Title: Membrane method and device for evaporating and concentrating waste liquid
Inventor: FUNABASHI KIYOMI
IPC: C02F1/04
Filed: 1991-05-27
Abstract: PURPOSE:To prevent leak by simple operation and to obtain high purity treated water for a long time by keeping water pressure on the condensed water side of waste liquid treating device within a specific range and keeping the water pressure on the condensed water side higher than that on the waste liquid side. CONSTITUTION:When treating waste liquid by a membrane evaporating concentrator 1 equipped with an evaporating chamber 12 and a cooling chamber 13 separated by a hydrophobic porous membrane 11, water pressure in the cooling chamber 13 is kept in the range of 10 to 500KPa and water pressure in the cooling chamber 13 is kept higher than that in the evaporating chamber 12. When the waste liquid is evaporated, the vapor is diffused in a hydrophobic porous membrane 11 and condensed in the cooling chamber 13. And after sodium sulfate in the waste liquid is concentrated on the surface of the membrane 11 to deposit it in the membrane and the waste liquid enters the membrane 11, the waste liquid reaches the cooling chamber 13 to produce liquid flow. At that time, as water pressure in the evaporating chamber 12 is higher than that in the cooling chamber 13, sodium sulfate deposited in the membrane 11 is washed by cooling water flow to restore hydrophobic property of the membrane.

Title: Automatic frequency control circuit
Inventor: TSUTSUI KOICHI
IPC: H03J7/02
Filed: 1994-06-02
Abstract: PURPOSE:To attain a high speed locking of the automatic frequency control circuit of a receiver of plural subcarrier signals. CONSTITUTION:The automatic frequency control circuit of a quasi- synchronization demodulator is provided with an orthogonal converter 1 converting the center frequency of the frequency component of an input signal being the synthesis signal of plural subcarriers to a base band being 0Hz. Plural subcarrier separator sections 21 at the post-stage extract the band nearly equal to the low frequency width of information sent by each subcarrier set to 0Hz. A frequency discriminator 22 discriminates the frequency around 0Hz for each output of plural subcarrier separator sections 21. A changeover means 23 selects alternatively any of plural outputs of the frequency discriminator 22. A loop filter 3 smooths outputs of the changeover means 23. A variable frequency oscillator 4 controlling the frequency by using the output of the loop filter 3 for a control signal allows the orthogonal converter 1 to implement conversion based on the output.

Abstract: PURPOSE: To easily and surely perform the adjustment of the height of the pickup arm with a simple constitution, by absorbing the change of the distance between shafts while holding the driving force through coupling of the output and input pulleys with elastic belt, in the full automatic record players.  
     CONSTITUTION: The arm bearing 4 bearing the pick up arm 10 is moved left and right, up and down, by the left and right motor 16, up and down motor 17, pulley 29, input pulleys 24, 18 linked with the elastic belt 28 such as rubber, and worm gear driving the cam and clutch. The height of the bearing 4 is adjusted with the adjusting screw 3 in which turning is stopped with the compression spring 14 after adjustment. Further, the displacement between the shafts of the pulleys 29, and 24, and pulleys 29 and 18, is absorbed with the elastic force of the belt 29 to hold the driving force. With this constitution, without individual adjustment of pickup arm, lifter, and arm rest, the adjustment of height can be made by one operation even at the pickup arm driving.

The locus of a contact 44 is slightly slided after contact between the contact 44 and an IC chip C2. Thereby the sliding face of the IC chip C2 is cleaned by the contact 44 and fine contact state can be maintained.
