Title: Method for cold rolling of stainless steel sheet
Inventor: YAMAMOTO HIROYASU
IPC: B21B3/00
Filed: 1988-02-18
Abstract: PURPOSE:To enable rolling an austenitic stainless steel sheet by a large draft and to reduce a ridging value for ferritic stainless steel sheet by heating a sheet in the inlet side at a specific temp. and rolling the sheet. CONSTITUTION:As for an austenitic stainless steel sheet, generation of martensite caused by rolling is prevented and deformation resistance is markedly reduced by heating the sheet at a temp. of 100-450 deg.C. Therefore, a draft per pass is increasable and the productivity is improved by reduction of the number of passes. As for a ferritic stainless steel sheet, a ridging value sharply drops as a temp. rises when a sheet is heated to 100-450 deg.C, so that a neat stainless steel product having no ridging is obtained when deep drawing is performed.

Title: Communication equipment
Inventor: IIZUKA NOBUO
IPC: G06T7/00
Filed: 1984-02-24
Abstract: PURPOSE:To facilitate an operation and at the same time to prevent a misoperation with a communication equipment by comparing the transmission or reception frequency set by a frequency setting means with the boundary frequency of a radio wave mode stored by a boundary frequency memory means by a mode discriminating means and switching the radio wave mode of the communication equipment when the radio wave mode is discriminated. CONSTITUTION:A frequency setter 10 sets a transmission or reception frequency, and the voltage signal corresponding to the set frequency is delivered to a mode discriminator 12. This discriminator 12 compares the input voltage given from the setter 10 with voltage levels supplied from boundary value generators 14- 18 respectively to decide the radio wave mode to which the set frequency belongs. This discriminated mode signal is supplied to a mode switching circuit 22. Then an analog switch 22A is switched in accordance with the corresponding mode.

Title: Ice making tray
Inventor: KUWARI YOSHIHIRO
IPC: F25C1/24
Filed: 1989-02-14
Abstract: PURPOSE:To make a transparent ice without protrusion over a whole upper tray by providing a water reservoir formed at an interval from the side face of the tray at the side face of the part of a lower tray, and a water reservoir cover extended from the flange of the upper tray for covering the top of the reservoir. CONSTITUTION:The top of a water reservoir 6 provided on a lower tray 2 is covered with a water reservoir cover 1g extended from an upper tray 1. Water surface of the reservoir 6 is not brought into direct contact with chilled gas to be higher at its temperature than that of the water surface of the other tray 1, and growth of ice is mostly delayed. Accordingly, even when the water surface of the tray 1 is all frozen, the water surface of the reservoir is not yet frozen, or the thickness of the ice is thin. The water of volumetric expansion due to the growth of the ice from the water surface of the tray 1 cannot be escaped, but concentrated at the reservoir of unfreezing state to raise the water surface level at the part or to break the thin ice on the surface of the reservoir to gush out. Thus, this part is eventually raised to eliminate the protrusion of the ice on the surface of the upper tray. Thus, the ice in the tray 1 is not whitened, and whitened ice remains only in the whitened ice remainder 4 and the reservoir 6 of the tray 2 in which completion of ice making is delayed.

Title: Cooler of liquid-cooled heat sink
Inventor: KOBATA MASAKAZU
IPC: H01L23/36
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To perform heat radiation effective for cooling a semiconductor element large in generation loss, by self cooling method of natural cooling, without using a rotor short in life such as a cooling fan, etc., but using liquid good in heat conductivity such as oil, etc., by arranging the vanes of a vane part in radial form in circumferential direction. SOLUTION: The vanes 41 of a vane part are arranged in radial form all around the periphery, and the contact faces are united by brazing to an element mounting plate 42 by vane mounting plates 43. Moreover, though the vanes 41 are made of plates the same in height, thickness, and length, they are arranged alternately to have longitudinal differences ΔL in circumference. This way, oil cooled all around the case flows in the fin vane part by arranging the vane structure of the heat sink in radial form, so the cooling efficiency is remarkably improved. Moreover, the action of the guide of cooling oil flowing into the vane part of the fin can be expected by providing a difference ΔL in level in longitudinal direction, and the heat radiation effect of the heat sink can be achieved.

Filed: 1980-03-18
Abstract: PURPOSE:To automate clamping of dies which sandwich an elastic material, and reduce the time for preparatory plan by setting the extent of die height and the permissible value between male and female dies with main and auxiliary digital switches and setting the sum of both as the bottom dead point of a slide. CONSTITUTION:In case urethane is sandwiched between male and female dies, a main digital switch 7 is set at required sandwinching height, and an auxiliary digital switch 8 is set smaller than the thickness of the urethane. If a slide adjusting button is pushed at the top dead point of the pressing device, a motor 1 runs to lower the slide and drive a disc cam 3, then the pulses proportional to the extent of descending of the slide are inputted to an interface 10, and the height of the slide is displayed in numerical value in a display tube 6. When the output of the counter 11 reaches the sum of the set values of the main and auxiliary digital switches 7, 8 a coincidence signal is outputted from the auxiliary comparator 14, and an auxiliary relay 17 goes ON, then the slide stops. The above enable the under surface of the slide to abut surely upon the male die and the clamping of the male die to be started immediately after the stop of the slide.

IPC: H01S5/026
Filed: 1986-02-21
Abstract: PURPOSE:To stabilize the operation of a semiconductor laser and reduce the noise induced by a returning light by a method wherein the light receiving surface of a photodetector is formed into a shape with which a laser beam reflected by the light receiving surface does not return to the emitting end surface of a semiconductor laser. CONSTITUTION:A forward bias voltage is applied to a semiconductor laser 3 through a termi nal 18 and a reverse bias voltage is applied to a photodetector 4 through a terminal 22 with an n-type electrode 19 as a common electrode. By the application of such bias voltage, laser beam is created in the light emitting region 16 of the semiconductor laser 3 side and laser beams L1 and L2 are emitted from a front emitting end surface 17 and from a back emitting end surface 5 respectively. The backward emitted light beam L2 penetrates into a light detecting surface 26 composed of a cylindrical inner wall surface through an aperture 25 at the position apart from the surface 5 by a distance (g). The penetrating light beam l1 is detected by an active layer 9b and partially reflected by the inner wall but a reflected light beam l2 is detected so as to be absorbed into the light receiving surface 26 by the multipath reflection on the cylindrical inner wall surface. With this constitution, the instability of the operation of the semiconductor laser 3 caused by a returning light beam can be avoided and the output fluctuation and the returning light noise of the laser beam L1 can be reduced.
