Title: Producing device for welded pipe
Inventor: TSUTA NORIO
IPC: B23K31/02
Filed: 1986-06-11
Abstract: PURPOSE:To effectively prevent the occurrence of an edge wave by heating a part other than both edges of an object to be formed with a cross section formed to nearly a circle before both edge parts which are met are welded and cooling both the edge parts and maintaining sufficient temperature difference. CONSTITUTION:The cross section of a laminar coil plate 1 which is conveyed continuously is formed to nearly the circle by a group of forming rolls. Next, both the edge parts 4 are met by a fin pass roll and welded by a welding means to obtain a welding pipe. The part other than both end edge parts 4 mentioned above is heated by a heating means 10 such as high-frequency induction, a gas burner, an infrared heater, etc., at the position of the inlet side of the material from the above-mentioned welding means and both the edge parts 4 are cooled by a cooling means 11 such as air jet, water jet, liquid nitrogen, etc., in the titled welded pipe producing device. In this way, the sufficient temperature difference is formed between the edge parts 4 and the part other than the edge parts and the compressive stress of the edge parts 4 is moderated to prevent the occurrence of the edge wave.

IPC: G03G9/09
Filed: 1989-05-30
Abstract: PURPOSE:To uniformize the brightness of images by specifying the relation between the viscoelasticity of three primary color toners and the viscoelasticity of a black toner at a storage modulus of elasticity. CONSTITUTION:The relation between the viscoelasticity (tandelta) of the three primary colors at the storage modulus of elasticity [G'(omega)]=10<5>(dyn/cm<2>) and the viscoelasticity (tandelta) of the black toner is so determined as to attain the relation; tandelta of the three primary color toners < tandelta of the black toner. The toner constituting the black part where the thickness of a toner layer is reduced by the removing treatment of the under color layer, i.e. the black toner is provided with the higher tendency to have brightness than the other three primary color toners, by which the brightness over the entire part of the color image is uniformized and the image quality is enhanced.

Filed: 1987-05-30
Abstract: PURPOSE:To prevent the lowering of a processing ability at a mail matter distribution device or the like by distributing in turn the paper sheets carried by its carrying means to each of other plural carrying means when the jam of paper sheets are detected. CONSTITUTION:A mail matter is taken out one by in turn in the state of a standing position from a supply portion 1, and its postal zone number is read at a reading portion 7 via a carrying passage 5, and then, a CPU 21 opens an equivalent, for example, distribution gate 11c, and a mail matter is housed in a classification box 15c.

Filed: 1986-06-12
Abstract: PURPOSE:To prevent a plastic-sealed semiconductor device from being corroded to improve a moisture-proof property, by jointing a bonding pad with a metal whose ionization tendency is larger than that of the metal forming the bonding pad. CONSTITUTION:An Al bonding pad 2, which is connected with an Al wiring 5 to perform bonding of a metallic thin conductor 6, is formed on a layer film 3 formed on a semiconductor 10. Mg film 1 is formed in contact with the pad 2. Then, Al of the pad part is ionized to become Al<3+> due to invasion of water from the outside, and a reaction 2Al<3+> +3Mg  2Al+3Mg<2+> occurs because an ionization tendency of the Mg film 1 jointed with the pad 2 is larger than that of the Al. Hence, the plastic-sealed semiconductor device can be prevented from being corroded, capable of improving moisture-proof property.

Title: Alarm transfer system
Inventor: KAWASHIMA HIROMI
IPC: G08B29/02
Filed: 1988-06-06
Abstract: PURPOSE:To detect the generation of an alarm and operation of an alarm output circuit and to discriminate the presence/absence of omission of a unit by transferring alarm signals indicating the normal and abnormal states of a device to an alarm collection circuit from the alarm output circuit. CONSTITUTION:When a device is abnormal, a switching section 5 connects a DC generation circuit 7 which an alarm transferring line 8 in accordance with a signal (b) inputted from an alarm output circuit 3 and indicating the abnormality and the DC signal of the circuit 7 becomes an alarm signal (c) and is transferred to an alarm collection circuit 9. Upon detecting the DC alarm signal, the circuit 9 displays that the device is abnormal. When a unit omission is produced due to the omission of a signal monitoring section 1, etc., the alarm transferring line 8 is set to 'OPEN' state and the alarm signal (c) from the signal monitoring section 1 does not reach an alarm section 2. Therefore, the occurrence of the unit omission can be recognized at the alarm collection circuit 9 because the alarm signal (c) is not inputted.

Title: Fet logical circuit
Inventor: OOTSUKA TOMOYUKI
IPC: H03K19/017
Filed: 1983-07-28
Abstract: PURPOSE:To perform high-speed operation by making the working area of FETs of a source follower part into a saturation area, applying a reverse bias between the gate and source all the time, and preventing an increase in junction capacity. CONSTITUTION:When a low-level pulse is applied to an input IN, almost no current flows through FETs 1 and 2. A constant current by an FET5, however, flows to a Shottky barrier diode SBD1, so the amount of source voltage shifting by the Shottky barrier diode SBD is n.Vbi (Shottky barrier voltage) and a voltage falls securely below that of the source follower part. Thus, when a bias difference is provided, junction capacities Cgs and Cgd of the FET3 are prevented from increasing to speed up the operation.
