Title: Selective call receiver with battery saving function
Inventor: KONDO HISASHI
IPC: H04W88/02
Filed: 1995-04-28
Abstract: PURPOSE: To execute effective battery saving in a selective call receiver which needs to execute received frequency channel sweep. CONSTITUTION: A radio part 2 can lock the received frequency channel of a selected call signal received by an antenna l by the frequency control of a first local oscillation circuit 31. The radio part 2 receives/demodulates the selected call signal received by the locked frequency channel and generates received data S3. A control part 5 intermittently operates the radio part 2 at a first BS mode adjusted to the sweep timing of received frequency channel sweep until a synchronizing signal is detected from received data S3 in a previously decided first BS period after power is supplied. When the synchronizing signal cannot be detected from received data S2 within the first BS period, the control part 5 intermittently operates the radio part 2 at a second BS mode where the operation period rate of the radio part 2 is less than the first BS mode in received frequency channel sweep.

Title: Probe inspecting method
Inventor: ISHIHARA KENICHIRO
IPC: H01J37/28
Filed: 1990-04-20
Abstract: PURPOSE:To evaluate a probe, to grasp the measurement accuracy of a device, and to grasp the optimum scanning direction by taking a measurement while rotating a standard sample which has a perpendicular surface at the same angle as the angle of the scanning direction of the probe. CONSTITUTION:The standard sample 9 is arranged in such a direction that the Y-axial scanning direction of the probe 8 matches the pattern direction of the standard sample 9 and the perpendicular surface of the pattern comes to the side of the probe 8 in an X-axial scanning direction. In such a state, the probe 8 is put in X-axial scanning motion. Then an angle signal generator 4 generates an optional-angle signal theta and the angle between the scanning direction of the probe 8 and the sample 9 is rotated by the same angle to put the probe in scanning motion. Thus, the probe is put in the scanning motion while the sample 9 and scanning direction are rotated by the same angle to put the probe 8 in the scanning motion in the repetitive direction of the pattern of the standard sample 9 at all times. This is repeated to one rotation (350 deg.). Thus, the angle signal theta is varied over the entire periphery from 3 deg. to 360 deg. to obtain the track 11 of the tip of the probe 8, and consequently the inclination of the tip over the entire periphery of the probe 8, thereby measurement and inspection of the shape of the probe tip part is attained.

Abstract: PURPOSE:To enable to accurately move an ink ribbon and to print at high speed, by a construction wherein the spacing between a printing head and a platen can be varied, and the spacing is adjusted in accordance with the kind of an ink ribbon. CONSTITUTION:In a wire dot printer, the spacing between the printing head and the platen is made to be adjustable. When printing in colors by using an ink ribbon in which colors are separately provided in the width direction of the ribbon, the spacing is set to be wide, thereby enabling accurate movement of the ink ribbon, at the sacrifice of printing speed. When printing in colors by using an ink ribbon in which colors are separately provided in the longitudinal direction of the ribbon or when printing by using a monochromatic ribbon, it is unnecessary to move the ribbon in the width direction thereof, and the spacing is set to be narrow to enable high-speed printing.

CONSTITUTION:In a shaking separator equipped with the sorting part of blending rice, while blending rice is fluidized from the supply side 15a of a high position in the longitudinal direction of a shaking sorting plate 15 to the discharge side 15b of a low position, blending rice is sorted by performing oblique and vertical reciprocating motion in the cross direction, separated and sorted to unpolished rice and paddy by a partition plate 18 of unpolished rice and a partition plate 19 of paddy arranged in the discharge side 15b.

Abstract: PURPOSE:To improve working efficiency in attaching easily an elastic wire rod to a lever for controlling heating power without caulking made by using a caulking pin and also supply surely the minimum gas flow rate by a method wherein the coil part of the elastic wire rod is attached to the lever for controlling heating power and this elastic wire rod is arranged at a fixed location. CONSTITUTION:The coil part 11a of an elastic wire rod 11 is inserted into the attaching part 12a of a lever 12 for controlling heating power and in putting the bent part 11b at one end of the part 11a on a stopper part 12b a straight line part 11c is forcibly in contact with a projection 12c for positioning. When the lever 12 is rotated in the left direction, a needle pin 13 inserted into a needle axis 9 is moved gradually in the direction of the axis along a slit 12d and at the location near the point of (weak) heating power an elastic part 11d begins to be in contact with the pin 13. Then, when the axis arrives at the location of the (weak) heating power, the axis 9 is subjected to a fixed preset load through the pin 13. Because a valve part 9a presses a valve seat 10 with pressure by using this load to carry out sure gas seal, gas flows through a bypass to bring the heating power in (weak) condition.

Filed: 1986-05-12
Abstract: PURPOSE:To retard the penetration of a silver ion onto the anode side to increase storage performance by placing a viscous liquid layer obtained by dispersing trivalent chromium oxide in alkali hydroxide solution on the side between a separator and a cathode mix or an anode gel. CONSTITUTION:A viscous liquid layer 26 is placed between a separator 14 and an anode gel 16. The viscous liquid is prepared by dispersing trivalent chromium oxide in a viscous alkali hydroxide solution containing carboxymethylcellulose or polyacrylic acid. When a silver ion produced by dissolution of silver oxide in a cathode mix 12 penetrates in the gel 16 through the separator 14, the contact of the silver ion with zinc is disturbed by the layer 26 to prevent internal short circuit. By preventing internal short circuit caused by the penetration of silver ion, storage performance of a battery is increased.

Title: Booster circuit
Inventor: HASHIMOTO RIYOUTA
IPC: H02M3/155
Filed: 1995-04-06
Abstract: PURPOSE: To always obtain a constant boosted voltage from a booster circuit regardless of the fluctuation of the input voltage of the circuit by controlling the output voltage of the circuit to a constant value by turning on a transistor by means of a voltage regulating element when the voltage generated from a secondary-side coil becomes higher than a prescribed value and turning on the transistor when the voltage does not reach the prescribed value. CONSTITUTION: Both capacitors C1 and C3 are gradually charged by repeatedly turning on and off a transistor Q1. When the second capacitor C3 is charged to the sum of the voltage of a Zener diode ZD1 and the base-emitter voltage of the transistor Q1, the diode ZD1 starts to cut the base current of the transistor Q1 even when the diode ZD1 is not completely turned on when the transistor Q1 is turned on. Thus the diode ZD1 changes the turning-on and tuning-off periods of the transistor Q1 so that the voltage of the capacitor C3 can become the sum of the voltage of the diode ZD1 and the base-emitter voltage of the transistor Q1. The voltage of the diode ZD1 is always fixed at the gate-source voltage of the FET regardless of the fluctuation of the input voltage.
