Title: Electronic timepiece of hand-indication type
Inventor: MURATA MITSUHIRO
IPC: G04C3/14
Filed: 1983-10-28
Abstract: PURPOSE:To maintain an indication to be correct when the indication of hands is changed, by moving the hand at high speed in the direction in which a small amount of movement of the hand enables the change when a state of indicating a current time is changed to a state of other kind indication related to an additional function. CONSTITUTION:When a stem 3 is set in a twice-pulled position 3c when a button 4 is in a pulled position 4b, a hand 1 is put in a state of indicating an alarm set time. In other words, the hand 1 is moved at high speed in a first direction and, as a result, is shifted to the state of indicating the alarm set time. When the stem 3 is returned to a normal position 3a from the state in which the hand indicates the alarm set time, the hand 1 is moved at high speed in a second direction opposite to the first direction and returns to a state of indicating a current time.

Title: Method for removing oxide scale in wire rod producing stage
Inventor: KURAUCHI NOBUYOSHI
IPC: H05K3/00
Filed: 1987-08-13
Abstract: PURPOSE:To perfectly remove oxide scale from the surface of an Ni or Ni alloy wire rod in a short time during production, by rapidly cooling the wire rod from a high temp. after hot rolling with grooved rolls and by carrying out pickling. CONSTITUTION:An ingot of pure Ni, an Ni-Cu alloy or an Ni-Cr-Al alloy for a wire rod is cogged or bloomed and the surface flaws, etc., of the resulting square bar are removed. The bar is heated in a heating furnace and repeatedly subjected to rolling with grooved rolls and process annealing to form a wire rod of a desired diameter. This wire rod is rapidly cooled from >=600 deg.C at >=50 deg.C/sec cooling rate to innumerably crack oxide scale on the surface of the wire rod and the oxide scale is dissolved and removed in a short time by pickling the wire rod. The pickled wire rod is bright-annealed and repeatedly subjected to cold drawing and bright annealing. Thus, an Ni or Ni alloy wire rod is produced with superior productivity.

Title: Power supply device for uninterruptibe power supply work
Inventor: MATSUKAWA MITSURU
IPC: H02M7/48
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To supply electric power with less voltage fluctuation without interrupting the power system voltage, by supplying a sinusoidal drive control signal of fixed amplitude synchronizing with the power system voltage to a correction circuit block, and controlling the output voltage of an inverter with the drive control signal through a correction circuit block. SOLUTION: A drive control part 10 of an inverter 4 is provided with a main control block 11, and a sinusoidal correction block 12 which corrects the amplitude of the drive control signal for driving the inverter 4 of fixed amplitude outputted by the sinusoidal circuit 9 of the block 11. The output voltage of the inverter 4 phase-synchronizes with the system voltage, and is corrected so as to follow the system voltage when the system power source 1 is normal and is controlled so as to be the lower limit of the system voltage when the system power source 1 is in a power failure condition, by a closed loop control through the correction circuit block 12. It is thus possible to keep inverter voltage at the system voltage without having an adverse effect if a load change occurs, thereby supplying stable electric power to the load 3.

Abstract: PURPOSE:To realize an automatic play of a record, by shifting an arm base in response to an extent of displacement due to the tracing of the record sound groove with a tone arm in combination of a driving spring and a brake. CONSTITUTION:In the figure A, a rope 11 is pulled toward an arrow (a) by the force of a driving spring 14, and the pulled part 29c is pulled toward an arrow (a) with a stop pin 28 used as a rotary shaft. At the same time, a tone arm 7 is turned toward an arrow (b), and a brake part 29a hits and presses a rod 8 to prevent the shift of the rope 11 toward an arrow (a). In the figure B, the stylus tip of a pickup 6 traces the sound groove of a record and then has a displacement toward an arrow (c). As a result, the part 29a releases a contact with a rod 8 and then moves toward an arrow (a) by the force of the spring 14 until the state of the figure A is obtained. With repetition of such operations, the arm 7 has a displacement toward an arrow (a). When a play of the record is over, the rope 11 is shifted toward an arrow (d) as shown by the figure C. Then the arm 7 turns toward an arrow (d), and a roller 29b touches the rod 8 and then turns to move toward an arrow (d).

Title: Rolling treatment
Inventor: SEKIGUCHI KUNIO
IPC: B21B37/18
Filed: 1986-08-28
Abstract: PURPOSE:To improve the coiling performance of a coil box by operating a roll gap to roll the front end of the material to be rolled to the thickness larger than a target sheet thickness in the final rolling pass of a roughing mill of a hot strip mill. CONSTITUTION:The coil box coils the material rolled by the roughing mill having a horizontal rolling mill and feeds the un-coiled material to a finishing mill upon completion of the coiling. The front end lA of the material coiled by the coil box is rolled to the sheet thickness hA larger than the target thickness hB of the stationary part lB by operating the roll gap in the final rolling pass of the roughing mill if the thickness of the material subjected to the rolling treatment is small. The coiling performance of the coil box is thereby improved even if the material is thin.

IPC: G02F1/1337
Filed: 1993-08-17
Abstract: PURPOSE:To obtain a visual angle characteristic which is uniform and completely isotropic over the entire region of a cell and to improve display quality by applying a pretilt angle to the liquid crystal molecules of a liquid crystal layer of the surface of a substrate subjected to a positive orientation treatment. CONSTITUTION:A slope 3 inclines at a prescribed angle with the plane of the substrate 1 or the plane of an optical polarization storage film 2. The posture of the liquid crystal molecules 5 at the boundary is regulated by this microrecessed part 4. The many microrecessed parts 4 are formed on the optical polarization storage film 3. The orientation direction within the substrate plane of the liquid crystal molecules 5 is regulated by the polarization direction of the polarized light with which the optical polarization storage film 2 is irradiated in the orientation treatment stage; further, the pretilt angle theta of the liquid crystal molecules 5 is regulated by the angle of the slopes 3 of the microrecessed parts 4. The transverse width of the microrecessed parts 4 is required to be the width having some degree of freedom to the orientation in the intra-surface direction of the substrate of the liquid crystal molecules 5. Then, the function to impart the pretilt angle to the liquid crystal molecules 5 is formed in the oriented film having the optical polarization storage characteristic and, therefore, the liquid crystal molecules 5 rise in the specified direction and the visual angle characteristic is improved.

Title: Manufacture of semiconductor integrated circuit device
Inventor: TORII ZENZO
IPC: H01L21/3065
Filed: 1990-07-31
Abstract: PURPOSE:To realize an interconnection processing technique which does not use Freon gas by a method wherein, when a TiW film or a TiN film is processed by a dry etching operation, a mixed gas of SF6 and BCl3 whose ratio has been specified is used. CONSTITUTION:An SiO2 film 20 and a TiW film 21 are deposited sequentially on a semiconductor wafer 8 composed of a silicon single crystal; after that, a resist 22 having a prescribed pattern is formed on the TiW film 21; a mixed gas of SF6 and BCl3 is supplied to the inside of a chamber at a microwave plasma etching apparatus 1; the TiW film 21 is etched. In this case, it is preferable that the ratio of SF6 in the mixed gas is set at about 30 to 60%. When the ratio of SF6 exceeds 60%, a sidewall is undercut. When the ratio of SF6 is less than 30%, the etching rate of the TiW film is lowered and the shaved amount of the resist is increased. As a result, a selective ratio to the resist is lowered. When nitrogen gas in small quantities is added to the mixed gas of SF6 and BCl3, it is possible to surely prevent undercut of the TiW film.
