Title: Arm fitting type radio equipment
Inventor: HAMA NORIO
IPC: H04B1/38
Filed: 1993-06-16
Abstract: PURPOSE:To miniaturize a radio equipment body and to improve spurious interference by using a surface acoustic wave element as a resonance element for a local oscillation circuit part. CONSTITUTION:The surface acoustic wave element (SAW resonator) 1 is used as the resonance element to be used for the local oscillation circuit. A variable capacitor 2 is an element for adjusting oscillation frequency and capacitors 4, 5, 7 are elements for feeding back a signal to constitute a resonance circuit. The SAW resonator 1 is characterized so that reactance in several hundreds MHz is inductive and close to zero as compared with a conventional crystal oscillator and neighboring loss is extremely small and has high Q. As compared with a local oscillation circuit using a conventional crystal oscillator, all inductors can be omitted. Since an inductor is a coil and its volume is large as compared with other elements, the omission of inductors is extremely effective for the miniaturization of the radio equipment.

Title: Rotation detector
Inventor: IKEDA MASAJI
IPC: H02K7/20
Filed: 1984-07-13
Abstract: PURPOSE:To obtain a highly reliable rotation detector, by making magnetic poles cross a magnetic detection body to generate a pulse. CONSTITUTION:As a rotor 3 mounted on a rotating shaft 1 rotates with the rotation of the rotating shaft 1, magnetic poles composing a plurality of magnetic pole trains 2a-2c on the circumference thereof crosses the magnetic detection body 5 sequentially. As a result, since the magnetic poles in the plurality of magnetic pole trans 2a-2c and the magnetic detection body 6 are arranged close to each other, the magnetic pole varies from N, S and N in the polarity with the rotation thereof to generate a pulse of the same direction. Thus, a pulse is generated in magnetic detection body 6 to obtain a highly reliable rotation detector.

Title: Generating circuit of reference potential
Inventor: KUWABARA SUMIO
IPC: G05F3/24
Filed: 1983-08-09
Abstract: PURPOSE:To attain the suitable application of a dynamic semiconductor memory circuit to a reference potential circuit by providing a supply circuit for current of a comparatively high voltage produced by the low power consumption characteristics obtained by a dynamic action and a boot-up action. CONSTITUTION:A reference potential Vref is lowered and a booted-up potential Vx is reduced less than the difference between the power supply voltage Vcc and the threshold voltage VTP of a p-channel transistor Q (shown by a round mark). Thus a transistor Q2 is kept on for a period T3 when a control signal phi3 is kept under a negative state. Then a current is supplied to a reference potential output line 10 from the Vcc via a transistor Q1 for a period T1 during which a control signal phi1 is kept negative. While the Q2 is kept off when the Vref is set at a high potential. Thus no current supply circuit is formed to the line 10. Therefore the current is supplied to the line 10 when the level of the Vref is lower than the voltage of the Vcc. Then the potential Vref having a high level corresponding to the rise of the voltage of the Vcc is delivered.
