Title: Manufacture of wrapped steel tube
Inventor: KISE TOSHIHIRO
IPC: B21D5/14
Filed: 1985-12-20
Abstract: PURPOSE:To improve manufacturing efficiency of a wrapped steel tube with a prescribed lap width by controlling a pressing force of a bending roll loaded on a steel plate and bending the steel plate with smaller radii of curvature than that at expansion work and the radii sequentially changed. CONSTITUTION:A steel plate 1 is bent by bending rollers 4, 5a, and 5b to manufacture a wrapped steel tube 6. The pressing force of the upper roller 4 onto the plate 1 is controlled to make radii of curvature Ra, Rb, and Rc of respective parts (a), (b), and (c) sequentially larger in due order. The radii Ra, Rb, and Rc at bending work are made to be smaller than the radius Ro at expansion work to positively obtain an accurate roundness of the outside surface of a cylindrical shape after the expansion work. As the result, the wrapped steel tube 6 with a prescribed lap width is manufactured.

Title: Recrystalization by a plurality of laser beams
Inventor: MATSUOKA HIDETATSU
IPC: H01L21/268
Filed: 1987-11-12
Abstract: PURPOSE:To suppress the development of undulation at the surface of recrystalization and stripping out of a substrate, by irradiating a principal beam which melts and crystallizes sweepingly a nonsinglecrystal semiconductor layer and further, applying an auxiliary beam, energy of which is smaller than that of the principal beam to a molten region which takes place behind the forward direction. CONSTITUTION:A fine crystal poly Si layer 4 is attached onto a substrate 3 consisting of insulating materials such as SiO2. A principal beam 1 which is radiated out of an Ar ion laser and has an output power approximately 3W irradiates the Si layer 4, while moving in the left direction. In this way, receiving laser irradiation, the Si layer is once molten into a melting liquid 5 and with the movement of the beam, its liquid again congeals into the solid state while making right hand singlecrystal Si 6 grow crosswise. The moving speed of the principal beam is the same as that of ordinary laser recrystallization. And an auxiliary beam having an Ar ion laser beam, output of which is approximately 0.3 W irradiates to a part which is in the vicinity of end faces where the melting liquid congeals into the solid state again. Oscillation and fluidization of the melting liquid are controlled by irradiation of the auxiliary beam and undulation and stripping of the surface of recrystallization are suppressed.

Filed: 1993-10-25
Abstract: PURPOSE:To provide a high-molecular dispersion type liquid crystal display device having high light scattering ability in the case the device is turned off, and the high contrast of a displayed picture. CONSTITUTION:In this high-molecular dispersion type liquid crystal display device provided with a high-molecular dispersion liquid crystal layer in a cell obtained by bonding a pair of transparent substrates 11 and 12 provided with a transparent electrode through a sealing material; a frosted glass having fine ruggedness on its inner surface is used as the substrates 11 and 12. In a state where electric field is not impressed, a refractive index is different between liquid crystal and the substrates 11 and 12, and light is scattered on a boundary between the liquid crystal and the substrates 11 and 12. The area of the boundary is increased owing to the ruggedness of the substrates 11 and 12, and light scattering efficiency is improved. Then, the randomness of the orientation of liquid crystal molecules is improved, and the scattering ability is more enhanced. In a state where the electric field is impressed, the refractive index is nearly the same between the liquid crystal and the substrates 11 and 12, and the light is hardly scattered. Therefore, the contrast of the display becomes high.

Title: Gear shifting controller for automatic transmission for vehicle
Inventor: IWATSUKI KUNIHIRO
IPC: B60W10/103
Filed: 1985-12-20
Abstract: PURPOSE:To make a shift shock reducible with a small-sized accumulator, by installing a device which alters and sets a timing variation in feed hydraulic pressure to a frictional engaging device from the specified timing to be detected during gear shifting. CONSTITUTION:When the specified timing during gear shifting, that is, timer duration to be determined by a piston position of the accumulator set up in an oil passage leading to a frictional engaging device elapses, a variation in feed hydraulic pressure to the frictional engaging device from this time is altered and set up, and it is controlled so as to cause a shift shot to be smaller. Here, in case a device detecting the specified timing, for example, a timer gets out of order, altering and setting of the timing variation in this feed hydraulic pressure are suspended. With this method, occurrence of such nonconformity that the shift shock comes to be increased on the contrary by performing control over the feed hydraulic pressure is preventable. Thus, a shift feeling is made maintable so favorably.

Abstract: PURPOSE:To produce an ALC panel hard to release by pouring an ALC raw material slurry in the space between a calcium silicate thin plate and a cementitious or ceramic thin plate to superpose both plates one upon another to partially cure the slurry and subsequently subjecting the whole to autoclave ageing.

Title: Range hood fan
Inventor: FURUYA YOSHIAKI
IPC: F24F7/007
Filed: 1988-11-15
Abstract: PURPOSE:To make a self-regulative means secure order concerning the temperature of the atmosphere in an electronic circuitry box, when the temperature of the circuitry box increases beyond a specified point, by making the self-regulative means open the circuit to the light, a cause of the heating, to turn it off. CONSTITUTION:A light 5 can be turned on exclusively by means of its control switch 7 independent of the control of a fan 2. If the light 5 is left lighted with the fan 2 at rest for a relatively long time, for example, when it is forgotten to turn it off, the heat of the lighting penetrates through a partitioning wall 8 into a box 3 containing electronic circuitry in which the temperature of the atmosphere increases beyond the allowable temperature for the semiconductor devices, and the like. In such a case, when the atmosphere in the circuitry box 3 reaches a specified temperature before it exceeds the allowable temperature, a temperature-sensing switch 10 acts to open the circuit to the light 5 independent of a bidirectional thyristor 11 in a conducting state; the light 5 is thus turned off by self-regulation. Thus the heating of an electronic circuitry box 3 by the lighting of a light 5 is prevented by elimination of the cause and the temperature of the atmosphere in which electronic circuitry is placed is maintained in good order.

IPC: G11B19/04
Filed: 1986-12-03
Abstract: PURPOSE:To manufacture inexpensively titled device and to shorten a memory releasing time by storing electronically a signal used for loading or removing a recording carrier. CONSTITUTION:When a switch 40 is closed in a moment by opening or closing a cover, the Q output of a T-FF70 comes to be H, thus, an RS-FF72 is set and the Q output of RS-FF72 comes to be H. Simultaneously, the Q' output of the RS-FF72 comes to be L, and therefore, the T-FF70 is cleared and the Q output comes to be L. Since a memory circuit 42 receives the supply of the power from a back-up power source 44 different from a main power source 52, the RS-FF72 is set in accordance with the opening and closing of the cover of a disk drive regardless of the condition of the main power source 52. Since the replacement of the recording support is stored electronically, the reliability is higher and the device can be manufactured less expensive than a mechanical memory mechanism even the constitution is simple.
