Patent JP-H03270182-A (JP)
Title: Laser oscillator
Inventor: MOCHIZUKI MANABU
IPC: H01S3/038
Filed: 1990-03-20
Abstract: PURPOSE:To minimize fluctuations in load impedance and provide a uniform electric field to the entire region of a discharge tube by allowing a discharge electrode board to be so laid out on both sides of a laser discharge tube as to face each other and contain sheet-like sections which directly face each other without the presence of the laser discharge tube. CONSTITUTION:Discharge electrode boards 3 and 5 are respectively provided with sheet-like sections 3b and 5b which directly face each other without allowing a laser discharge tube to lie between excepts for sections 3a and 5a which directly face each other by way of the laser discharge tube 1 which stands between. The sheet-like sections 3b and 5b are adapted to work as a capacitor because of the capacitance between the discharge electrodes. Since the discharge electrode boards 3 and 5 constitute the capacitor in this manner, a matching circuit 7 can be made of only an L type filter which comprises a coil 7a and a capacitor 7b. Moreover, each edge 3c and 5c of the discharge electrode boards 3 and 5 are positioned far from the discharge tube 1. Therefore, the edge effect generated on the ends of the electrode will not affect the discharge. It is, therefore, possible to increase the effect which provide an equal electric field to this laser discharge tube 1.

Title: Reversing-type seal
Inventor: TAKAHASHI HIROAKI
IPC: B41K1/40
Filed: 1995-03-01
Abstract: PURPOSE: To improve the lock operability and the replacement of an ink pad by providing a protrusion at the inside surface of an interlockingly operating part, and providing a guide groove, which guides the protrusion to a slit, in connection with the slit at the short side face of an outer frame. CONSTITUTION: When an outer frame 1 is completely pressed down, a seal main body 14 is reversed at 180 degrees to be sealed. When a shaft stopper 16 is rotated in the direction of the slit along a guide groove 4 by a lock actuator 17 and the actuator 17 is set parallel to a pressing surface, a protrusion 18 provided at the inside surface of the actuator 17 is guided to the groove 4 to be moved to the slit. When a force for pressing down the frame 1 is drawn in this state, the frame 1 tends to be lifted upward by the drag of a coiled spring 19, and a reversing shaft 15 tends to rise along a control slit 6. However, the protrusion 18 is brought into contact with the slit to be engaged and the shaft 15 cannot rise, and the body 14 is locked in the state reversed at 180 degrees.

IPC: F16J10/02
Filed: 1979-06-04
Abstract: PURPOSE:To achieve easy manufacturing and high precision of a cylinder whose sectional configuration is given by hemi-circles opposed on both sides and intermediate lines, by reforming the both hemi-circles to longer arcs. CONSTITUTION:An engine 1 principally consists of a cylinder 2 and a piston 3. The cylinder 2 is approximately oval, made up of a pair of circular parts 4 on both ends and intermediate linear parts 5. The piston 3 is similar to the cylinder 2. Each circular part 4 of the cylinder 2 is shaped as an arc 6 which has extensions 6a successively extending from the circular parts 4. Both ends of each extension 6a are transversally connected by lines 7. Those circular parts 4 and linear part can be easily manufactured on account of elimination of the need for accurately locating tangents of lines 7 to arcs 6. A piston ring 11 can exactly follow the piston 3 so that a sealing effect may be improved.

Abstract: PURPOSE: To facilitate an effective liquefaction and an anaerobic digestion using low power at the same time, by charging an organic waste solution into the liquefying zone of a vessel where the waste solution is liquefied, and then flowing the treated waste solution into the gasifying zone of the vessel where the waste solution is gasified by heating under agitation.  
     CONSTITUTION: An organic waste solution introduced through a stock solution inlet pipe 8 into the liquefying zone 21 of a vessel 1 is heated by a liquid in the gasifying zone 22, and decomposed into volatile aliphatic acids by the action of liquefying bacteria under an anaerobic condition without agitation, so as to generate gases mainly composed of CO 2 . A generated gas control valve 11 is arranged on a gas discharge pipe line 10, and controlled by a level guage 9. The liquid in the zone 21 flows into the zone 22 due to a gas pressure and a level head. In the zone 22, the liquid is heated and agitated by steam and agitating gas fed through a steam inlet pipe and an agitating gas inlet pipe 15, and decomposed from the volatile aliphatic acid state to gases mainly composed of methane gas under an anearobic condition by introduced gasifying bacteria. The generated gas is fed through a gas discharge pipe 13 into a gas holder, while the disposed water is discharged through an outflow pipe 12.

Title: Automatic tracking device for magnetic recorder/reproducer
Inventor: MIYAWAKI NORIHIKO
IPC: H04N5/783
Filed: 1979-06-01
Abstract: PURPOSE: To avoid the noise occurrence over the entire surface for the steal reproduction or the like, by applying the signal of the fixed level to the electric-mechanical conversion element of the magnetic head when the level of the reproduced signal is less than the fixed level and then giving the replacement by the fixed distance.  
     CONSTITUTION: For the two-head VTR, the output reproduced through head 19 delivers the error signal to adder 16 via amplifier 20, detectors 21, BPF22, synchronous detecting circuit 23 and smoothing circuit 24 each. On the other hand, the output of detector 21 applies level signal C to adder 16 to give the displacement to head 19 by a track pitch in case no head output exists and via sample holding circuit 40, Schmitt circuit 41 and smoothing circuit 24 each. The reproduction velocity selection signal is supplied to adder 16 from waveform generator 26, and head 19 is controlled by the output of adder 16. At the steal reproducing time and others, head 19 scans the tracks having different azimuths or the guard band track, and then has the replacement to the next track by signal C when no head output exists. Thus the noise can be avoided over the entire surface.

Abstract: PROBLEM TO BE SOLVED: To prevent short-circuiting caused by contact between contacts adjacent to each other by bringing a spherical crown member into contact with the inner peripheral surface of a recessed member so as to contact the outer peripheral surface of the recessed member with the opposing surface of a conductive member against an elastic member and electrically connecting the spherical crown member to the conductive member. SOLUTION: When the mushroom-shaped lead terminal of an IC package is contacted with the inner peripheral surface 22a of a recessed member 22, pressing is applied from the recessed member 22 to a conductive member 23, the outer peripheral surface 22b of the recessed member 22 is brought into contact with the opposing surface 23a of the conductive member 23 against an elastic member 24 and the lead terminal is electrically connected to the conductive member 23. By providing a plurality of elastic members 24, the movement of a contact 21 in the directions other then the pressing direction is made difficult and, by mounting the IC package on the contact 21, electric connection between the package and a substrate circuit is secured.  By providing an elastic insulating member 26 around the elastic member 24, shorting, deformation, deterioration or damage between the contacts 21 adjacent to each other is prevented.

IPC: C01B17/66
Filed: 1972-07-12
Abstract: PURPOSE: To easily recover SO 2  and formic acid as its methyl ester and recycle them in manufacture of anhydrous hydrosulfite by the reaction of sodium formate, SO 2  and caustic soda in an aq. soln. of methanol, by acidifying reaction mother liquor, followed by heating and distillation.  
     CONSTITUTION: Sodium formate, SO 2  and caustic soda are reacted in an aq. soln. of methanol to form anhydrous hydrosulfite Na 2 S 2 O 4 . After removing this reaction product, the mother liquor is regulated to pH≤1.5 with mineral acid such as sulfuric acid to decompose residual sodium thiosulfate, hydrosulfite, etc. into SO 2 . The liquor is then heated to 55W75°C to turn residual formic acid into methyl formate and distilled to recover the SO 2 , methyl formate and metanol. By adding alkali, the methyl formate and SO 2  are easily hydrolyzed and neutralized, and hence they can be used directly as raw materials for manufacturing anhydrous hydrosulfite.
