Title: Transfer system to transfer conveyor unit from one floor chain system to other floor chain system, and transfer system to branch and transfer conveyor unit from main chain track to side chain track.
Inventor: KARUROSU BUAN RIAADO
IPC: B65G47/52
Filed: 1995-03-07
Abstract: PURPOSE: To provide a transfer system and a method for transferring a conveyor unit to another floor chain system from one floor chain system without requiring a wide installation space and without a danger of stopping by biting-in of a pin.

Title: Moisture-absorbing breathing device for oil-immersed electric apparatus
Inventor: SAITO SHIGEMI
IPC: H01F27/14
Filed: 1986-03-06
Abstract: PURPOSE:To prevent erroneous operations of an air-discharging device, by providing a pressure relief device in the breathing system such as a breather tube or a chamber for receiving a moisture absorbing agent so that the pressure relief device normally isolates the chamber hermetically from the outside air and, if the pressure in the breathing system is increased, discharges air from the chamber to a pressure lower than that of the air-discharging device attached to the tank of an oil-immersed electric apparatus. CONSTITUTION:If a moisture absorbing breathing device is clogged by deposited moisture absorbing agent powder 12 or the like and the internal pressure of the breathing device is thereby increased, a hood 22 of a pressure relief device 8 rises up against action of a spring 23 and discharges air from a chamber 11 for receiving the moisture absorbing agent. The pressure within an oil-immersed electric apparatus is thereby prevented from being increased. When the pressure within the chamber 11 is decreased by relief of pressure, the hood 22 is automatically reset by the action of the spring 23 so that the outside air is introduced into the chamber 11 through the hood 22 to prevent the moisture absorbing agent 12 from absorbing superfluous moisture. In this manner, the internal pressure of the oil- immersed electric apparatus 1 is prevented from being increased to cause erroneous operation of an air-discharging device 7 and to stop power supply to the oil-immersed electric apparatus.

Title: Reproducing method for magneto-optical recording medium
Inventor: SHIBUYA GIICHI
IPC: G11B11/105
Filed: 1993-02-12
Abstract: PURPOSE:To reduce the influence due to the differences in size and shape of recording marks caused by recording power and conditions at a recording time when a magneto-optical recording medium performed with overwrite recording is reproduced. CONSTITUTION:A reproducing laser beam irradiates the magneto-optical recording medium by offsetting from the center of a recording track. The offset amount of the reproducing laser beam is adjusted by monitoring the error flag and/or the jitters component of a read signal at a reproducing time, and feeding back the information on them to a tracking servo system.

Title: Displacement determining system
Inventor: MIYAMURA MASATO
IPC: H01L21/60
Filed: 1981-03-31
Abstract: PURPOSE:To determine the displacement of a wire end from a pad by a method wherein a scanning line is drawn in specified relation with the known pad location and two points are detected whereat the scanning line intercepts the circumference of a wire end for determining the center of the wire end. CONSTITUTION:A command from a controlling system causes the center YP of a pad 12 to be read out and stored in a counter 22. A counter 21 is activated to gain access to a memory 8 through an access circuit 23 and data are supplied to a register 24 and then to a register 25. A signal rises when a counter receives an X1 signal, and the register 24 is activated and stores the signal X1, while the register 25 stores an X2 signal upon detecting a fall in the signal. The operator 26 determines the central point XQ by using two points X1 and X2 on the circumference of the end of wire 13 and yields a difference DELTAX between the XQ and XP in the form of a displacement quantity in the direction X. The same procedure is repeated for the quantity in the direction Y. This setup realizes a simple system wherein bonding position displacement quantities are detected properly and easily.

Title: Arc welding machine
Inventor: NAGASAKA MORITOSHI
IPC: B23K9/095
Filed: 1982-03-24
Abstract: PURPOSE:To improve operability of a welding machine and enable confirmation of selected welding condition at all times, by placing a switch for instruction to start operation and a signal generator for changing welding condition within reach of a worker and placing a starting circuit and circuits after a discriminating circuit at remote position. CONSTITUTION:A specified signal out of n kinds (n>=2) of signals of a signal generator 2 is set before starting welding. The output of the generator 2 is discriminated by a discriminating circuit 5 through a cable 3 as to which one out of n kinds it belongs. The result of discrimination is outputted to a welding condition setting circuit 7 through a holding circuit 6. When a switch 1 for instructing starting of operation is depressed in starting welding, a starting circuit 4 supplies a starting signal to a welding condition controlling section 8. By closing the switch 1, output of the generator 2 connected in parallel to it is also short-circuited. However, as the circuit 6 holds output of the circuit 5 just before closing of the switch, the circuit 7 continues to supply the specified welding condition to the controlling section 8. Accordingly, welding can be performed under selected condition.

Title: Semiconductor integrated circuit
Inventor: MORIKAWA TAKENORI
IPC: H01L21/331
Filed: 1990-02-27
Abstract: PURPOSE:To prevent increase in memory capacity or read/write time by forming a heavily-doped p-type semiconductor layer, which is in a p-type silicon substrate and underneath a heavily-doped n-type buried layer that needs resistance to alpha rays. CONSTITUTION:A p-type silicon substrate 1 is covered with a heavily-doped p-type semiconductor layer 2, on which a lightly-doped p-type semiconductor layer 3 is provided. The semiconductor layer 3 is covered with a heavily-doped n-type buried layer 4, on the surface of which a lightly-doped n-type epitaxial layer 5 is grown. In the semiconductor layer 2, the doping concentration is decreased in the depth direction (see fig. b), and an electric field appears in the opposite direction. The electric field prevents electrons, ejected by alpha rays, from diffusing from the substrate 1 toward the layer 4. This reduces the quantity of electrons that are collected in the layer 4. Therefore, it is possible to shorten read/write time without an increase in memory capacity.
