Abstract: PURPOSE: To pressure-weld the thin-walled steel pipes with good accuracy by gas- heating the butt faying surfaces of the pipes to around the melting temperature, fusion-welding the pipes under suitable pressure then holding the faying surfaces at the forging temperature and pressing the same under suitable pressure.  
     CONSTITUTION: After pipes P1, P2 are so set to clamps 1, 2 that their butt portion comes to the intermediate of the both clamps 1, 2, the pipes P1, P2 are fixed to the clamps 1, 2 by operating hydraulic cylinders 5, 8, thence the pressure of the extent of not producing any deflection around the weld zone is appled to the faying surfaces by operating a pressing device A and the burner center of a heating device B is aligned to the butt faces, after which the faying surfaces are heated by the device B to around the melting temperature to fusion-bond the faying surfaces. Thence, while the temperature at the weld zone is being maintained at the forging temperature range, the weld zone is pressed by the pressure of the extent of not producing any deflection around the weld zone by the pressing device A.

Title: Formation of polycrystalline semiconductor thin film and manufacture of thin-film transistor
Inventor: KAKINUMA HIROAKI
IPC: H01L21/336
Filed: 1994-07-14
Abstract: PURPOSE:To provide a method for forming a polycrystalline thin film by which the grain diameter of crystal grains can be increased without increasing the flow rate of material gas. CONSTITUTION:On a glass substrate 22, poly-Si 42 is deposited by PCVD to the thickness of l00nm as a first-layer polycrystalline layer 42. Then, on the polycrystalline layer 42, an amorphous layer 44 is deposited to the thickness of about 2nm so as to partially cover crystal grains 44 which constitute the polycrystalline layer 42. At that time, only the large grains 42a are exposed on the surface of the alpha-Si. Nextly, a second-layer polycrystalline layer 46 is deposited on the first-layer polycrystalline layer 42 on which the amorphous layer 44 is deposited. At that time, the poly-Si 46 regrows with the relatively large grains 42a which are exposed on the surface of the alpha-Si 44 used as crystal nuclei, therefore the grain diameter becomes large.

Title: Semiconductor integrated circuit device
Inventor: SAKAZUME TATSUMI
IPC: H01L27/092
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To protect a device against damage caused by an electrostatic dis charge in an OFF state. SOLUTION: When a power supply voltage Vcc is applied to a semiconductor integrated circuit device, a transistor 2 is turned on because a power supply voltage Vcc is applied to its gate, and a device such as an input buffer B or the like can be protected against breakdown caused by electrostatic discharge noises by making either a transistor 3 or a diode 5 absorb a overvoltage through the intermediary of the transistor 2. At this point, signals inputted through an input/output terminal P are inputted so as not to pass through a resistor of high resistance, so that the semiconductor integrated circuit device is not impeded in its high speed operation. A power supply voltage Vcc is not supplied to the semiconductor integrated circuit device, the transistor 2 is turned off because a power supply voltage Vcc is not applied.  At this point, when an electrostatic discharge is applied to the input/output terminal P, the resistor 4 absorbs an overvoltage because the transistor 2 is kept in an OFF state, by which devices such as a second electrostatic breakdown protective part ESD 2, the input buffer B and the others can be protected against breakdown.

Title: Transformer with reactor
Inventor: HAYASHI SHINICHIRO
IPC: H01F30/12
Filed: 1989-06-23
Abstract: PURPOSE:To reduce voltage variation rate and to prevent a high frequency noise by separating a voltage coil of commercial frequency and a coil of reactor function for noise reduction and by connecting a coil for reactor function to a polarity for common mode noise removal. CONSTITUTION:A high frequency noise of common mode which entered from an input terminal V-V of a reactor transformer enters coils 9 to 12. Since the coil is wound thick at both sides, it has inductance and a noise is reduced by the reactor function. Coils 9 to 12 are symmetrically positioned and influence a core 1 equally; therefore, noise due to leak magnetic flux does not influence a secondary coil. Impedance of coils 9 to 12 is small and its voltage does not drop because of a polarity of in-phase winding at a commercial frequency.

Title: Servo device
Inventor: HAYASHI HIDEAKI
IPC: G11B7/095
Filed: 1982-09-17
Abstract: PURPOSE:To ensure stable control of a servo device, by setting the maximum value corresponding to the target variation frequency and having no reply to an error signal having a level higher than said maximum value. CONSTITUTION:For tracking servo devices of various disks, the target value 0 is supplied to an input terminal T1 to drive an actuator of an optical pickup Pu with the signal amplified by an amplifying circuit A1 via an adder circuit ADD. An error signal obtained by the pickup Pu is amplified by an amplifying circuit A2 and then transmitted through a double-differentiating circuit AD having characteristics adverse to the eccentric component H of a disk DIS. Then the variation component larger than a straight line R is eliminated by a limiter circuit AR, and the negative feedback is applied to the circuit ADD through the next integration circuit AI. Thus an error signal having a high level such as a drop-out signal is reduced by a limiter AR. This avoids the large variation of loop gain.

Title: Flash fixing color toner with improved light absorbance
Inventor: ABE YUKI
IPC: G03G9/08
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To make the capability to absorb light by flash exposure satisfactory, to improve fixing capability and to obtain a desired color image by adding a visible to near infrared ray absorbing dye which serves as a light-absorbance improving agent and can be bleached and a bleaching agent to color toner. SOLUTION: Flash fixing color toner comprising a visible to near infrared ray absorbing dye which improves light absorbance and, at the same time, is bleached during flash fixing so that the color toner can exhibit the target color of the dye after fixing, and a bleaching agent, both of which are added to color toner, is used. By adding a light absorbance improving agent, a color toner which is highly light-absorbing can be obtained. Also, because the dye itself is bleached by flash fixing and does not exert any effect on the color hue of the dye, the toner can exhibit a target color as a color toner. As a color toner to which the light-absorbance improving agent is added, any toner conventionally used as a color toner which is fixed by a heating system or light emitting system can be used.
