Title: Logic circuit
Inventor: HORIUCHI TADAHIKO
IPC: H01L21/8238
Filed: 1989-07-21
Abstract: PURPOSE:To reduce an input capacitance and to avoid a problem of the reliability caused by emitter-base reverse biasing by incorporating a diode between two bipolar transistors(TRs) at the output side of a bi-MOS inverter circuit. CONSTITUTION:When a potential at an input terminal 1 transits from H to L, a pMOS TR 3 is turned on and the base potential of an NPN TR 7 is boosted. Succeedingly, the NPN TR 7 is turned on, a potential at a output terminal 2 rises to H. When the potential of an input terminal I transits from L to H, the set of Darlington connection between nMOS TR 5 and an NPN TR 8 is turned on and the pMOS TR 3 is turned off. Since a diode 10 is biased reversely, the nMOS TR 5 and the NPN TR 8 discharge the base charge of the NPN TR 7 at first and the level of the output terminal 2 goes from H to L through the diode 10.

Filed: 1993-06-30
Abstract: PURPOSE:To achieve a test without removing an electric motor which is incorporated into a system by short-circuiting either two phases of the three phases of the electric motor, applying a single-phase voltage to the remaining phase, and then at least measuring current in that state. CONSTITUTION:Voltage supply terminals u, v, and w of a three-phase AC electric motor 21 are connected to a short circuiter 25 via feeder lines 22. 23, and 24. The short circuiter 25 short-circuits, for example, the terminals v and w. A test current in a single-phase voltage is allowed to flow from a single-phase power supply 28 to the electric motor 21 via feeder lines 26 and 27. The potential between the terminals v and w is equal to 0, thus preventing the electric motor 21 from rotating and applying the single-phase voltage between remaining terminals u and v (w). At this time, current and voltage are measured by a current sensor 29 and a voltage sensor 30. The characteristics of the electric motor 21 are obtained by the circle diagram method etc. using the measurement values. A system controller 31 totally performs the control of the phase to be short-circuited, the control of the level of application voltage and waveform, and the control and test itself of latching and processing of a sensor signal.

Title: Sheet film pack
Inventor: OKUTSU TARO
IPC: G03C3/00
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent external light from entering from a gap between a guide rail and a pull cap by making the inclination angle of the guide rail in the thickness direction of the pull cap in a section perpendicular to the moving direction of the pull cap within a specified range. SOLUTION: In the section perpendicular to the moving direction of the pull cap 5 of the guide rail 9, when the inclination angle θ of the guide rail 9 to a reference line L in the thickness direction of the pull cap 5 becomes large on the outside (+ side), the gap between the pull cap 5 and the guide rail 9 becomes large, and a light shield property is deteriorated. When it becomes large on the inside (- side), the gap between the pull cap 5 and the guide rail 9 becomes small, and the operation resistance of the push-pull operation of the pull cap 5 is increased. The inclination angle θ of the guide rail 9 is preferably made within the range of -1.5 deg. to +1.5 deg.. A main cause that the inclination angle θ is changed exists in a temp. difference between a fixed side mold and a moving side mold of the mold for injection molding a pack main body 3.  The inclination angle θ lies within the allowable range by making the temp. difference 15 deg.C-45 deg.C.

Title: Band structure and molding method for band
Inventor: TANAKA SHINICHI
IPC: A44C27/00
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To provide band structure with which a band can be satisfactorily molded without deforming a decorative member or sinking it in the main body of the band at the time of molding even when the stereoscopically formed decorative member is used. SOLUTION: Concerning the synthetic resin band structure for which insert molding is performed by resin injected from one end in lengthwise direction so as to embed a decorative member 2 while exposing one part, a through hole 5 is formed on the decorative member 2 through the direction in which the resin flows. Therefore, since the resin injected in a metal die 10 flows inside the through hole 5 on the decorative member 2 in the case of performing the insert molding while arranging the decorative member 2 inside the metal die 10, the decorative member 2 does not receive large resistance by the injection pressure of resin so that the decorative member can be prevented from deforming or sinking in the main body of the band. Thus, even when the stereoscopically formed decorative member 2 is used, the band can be satisfactorily molded.
