Title: Connecting device for communication line
Inventor: KOMATSUDA TOSHIKAZU
IPC: G06F17/40
Filed: 1980-11-27
Abstract: PURPOSE:To allow the connection of communication line safely and easily, by electrically isolating both connected devices, not providing power supply to itself, obtaining the power supply from a part of the signal to the device and operating circuit elements. CONSTITUTION:When a signal SDa at a device A is 0, since the level of the signal SDa is higher than that of a signal SGa, a current flows via an element (r1), element (d), the element (f) is in cut-off, and since no current flows to the element (r2), a level 0 higher than the level of the signal SGb is delivered to the signal RDb at a device B. When the signal SDa is 1, since the level is lower than that of the signal SGa, the element (f) is in cut-on. Since a current flows to the element r2, the same level 1 as the signal SGb is given to the signal RDb. Thus, the both devices A, B to be connected are electrically isolated, the power supply is not provided in them, the power supply is taken from a part of the signal of the devices and the circuit elements (d), (f) are activated, allowing to connect channel lines.

Filed: 1979-12-21
Abstract: PURPOSE: To enable effective partial coating by varying the distribution of coating obscurely by making a gap between a car body and an adhesive tape, by adhering an adhesive tape with its end folded inside.  
     CONSTITUTION: A tape applied with adhesives is folded inside into two lengthwise at part 6 of its end and internal surface part 7 of the remainder applied with the adhesives is adhered to the end of coating film 3. The coating film with the bonded tape is mounted on the top surface of a car body at position (a) and while the edge of the folded part of the tape is positioned agreeing with boundary line c-d, the top surface of the tape is pressured to adhere the center part 8 of the internal surface to the car body, so that slight gap 9 will be formed between the tape and car body while folded part 6 is not adhered. Next, paint when sprayed scatters partially in  gap 9 as corpuscles and sticks and the distribution of the paint along boundary line  c-d becomes obscurely, so that a change in color tone will not appear sharply.

Abstract: PURPOSE:To lower ON resistance by making the resistivity of the surface layer of an N type base body functioning as a drain lower than that of the base body in a vertical power MOSFET. CONSTITUTION:The MOSFET is formed in such a manner that a P type region 2 is shaped to the surface of the N type Si base body 1 serving as the drain, an N<+> type source 3 is formed to the surface of the region 2, a P type region surface 2a between a source and the drain is used as a channel section and a gate electrode is shaped onto the surface 2a through an insulating film 4. The resistivity of the N layer 6 of the surface layer of the base body 1 is made lower than that of the base body 1, and the resistivity value is kept within an extent that the FET is pinched off when reverse voltage is applied to a PN junction. According to this structure, resistance in the lateral direction is reduced because of the layer 6, and all ON resistance can be decreased even when resistance in the vertical direction is large.

Title: Laser treatment apparatus
Inventor: KOBAYAKAWA YOSHI
IPC: A61B18/20
Filed: 1987-07-03
Abstract: PURPOSE:To improve the condensing state to a focus, by providing a nonvisible laser beam reflecting film to the rear surface of a coupling optical member and further partially providing a visible guide beam reflecting film behind said film and guiding treatment laser beam and visible guide beam from the front surface of the coupling optical member to respectively reflecting both beams by the reflecting films. CONSTITUTION:A operator confirms that a visible guide beam L2 is focused to emit a treatment laser beam L1 from a laser beam source 11. Since an optical membrane 16a permitting the visible guide beam L2 to transmit and reflecting only the treatment laser beam L1 is applied to the entire rear surface S2 of a mirror coupling optical member 16, the treatment laser beam L7 incident to the mirror coupling optical member 16 from the front surface S1 thereof is reflected from the rear surface S2 to be condensed to the focal position of an eye E to be treated. Further, since the optical membrane 16a receives no effect due to the thickness of optical membranes 16b, 16c, the disturbance of a wave front is not generated in the treatment laser beam L1 reflected by the optical membrane 16a. Furthermore, even the beam reflected from the rear surface generates no astigmatism and a focal position is also not shifted.

Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To vertically reduce bulk of a polyethylene terephthalate bottle (the bottle) by providing the top surface of the bottle-storing cylindrical body, whose side is capable of extending and contracting vertically, with a small hole through which the air inside the bottle escapes outside, and compressing the storing body from the top and the bottom. SOLUTION: The crusher is desirably structured such that the top 1 and the side 3 of the bottle 4 storing body are integrally formed, and that the bottom base 2 is attachable to and detachable from the lowest cylindrical part of the side 3; accordingly, the crushing utensil can store the bottle 4 in the manner of covering it from above, eliminate an extra operation and excel in strength when crushing the bottle. The bottom base 2 can be in any shape so long as it is detachable from the lowest cylindrical part of the side 3 and that it can be left standing at the time of storing the bottle 4; therefore, the bottom base 2 may be nearly in the same shape as the bottom cylindrical part of the side 3, or it may have the shape that serves as a cover when the storing body is contracted into a short cylinder. Thus, a compact and light crushing utensil can be obtained.

Title: Packing material for battery
Inventor: SASAKI KUNIHIKO
IPC: H01M50/184
Filed: 1983-09-14
Abstract: PURPOSE:To prevent any leakage of electrolyte by bringing a packing into close contact with the surfaces of a terminal plate, a current collector and the like by preparing the packing from a vinylidenefluoride-hexafluoropropylene-system fluorine rubber. CONSTITUTION:A vinylidenefluoride-hexafluoropropylene-system fluorine rubber is used as a packing material for a battery. This rubber is a polymer prepared by binding together fluorine rubber segments (soft segments) (B) and fluorine resin segments (hard segments) (A). Although the rubber exhibits a rubber elasticity at ordinary temperature because of the physical crosslink of the fluorine resin phase (A), the rubber behaves in the same manner as a thermoplastic plastic at a temperature not lower than the melting point. Accordingly, the rubber becomes in close contact with a battery case, a sealing plate and a current collector. Moreover, any escape of the packing is not caused by clamping, thereby enabling the liquid leakage resistance to be remarkably increased.
