Title: Light emitting device with light receiving element
Inventor: KIMOTO MASAHIKO
IPC: H01L31/12
Filed: 1984-09-17
Abstract: PURPOSE:To realize structure simplification and cost reduction and contrive to improve the signal/noise ratio by using a shielding member annularly arranged between the light receiving element and the light emitting element. CONSTITUTION:Light from the light emitting element 106 is reflected on the reflection plane 102a of the second cylinder 102 and on the outer peripheral surface 103b of the shielding member 103 and then put in irradiation to an object to be inspected which has bar codes via center of the first inner surface 101b of the first cylinder 101. When the irradiated part is a part of black bar code, the object to be inspected does not reflect that light, but reflects it in case of a white part, and the light is made incident to the light emitting element 105 via center of the second inner surface 101b of the first cylinder 101; thus, bar-code information can be read out. Since the first cylinder 101 is made of transparent synthetic resin, the refractive index of light of the light receiving element 106 becomes much smaller; accordingly, the noise made incident to the light receiving element 105 reduces, and the signal/noise ratio improves.

IPC: H02P8/14
Filed: 1988-08-05
Abstract: PURPOSE:To let the output torque of a motor be appropriate in an ordinary temperature environment and in a low temperature environment and to avoid waste of power by varying motor drive current in accordance with the change of environmental temperature. CONSTITUTION:A bimetal 8 detects an ambient temperature of a carriage driving mechanism, a load of a stepping motor.

When the ambient temperature grows higher, the reference voltage is raised to increase the driving current of the stepping motor. On the other hand, when the ambient temperature becomes low, with the reference voltage reduced the driving current of the stepping motor is decreased.

Inventor: TAKEHIRA KATSUMI
IPC: H01Q1/36
Filed: 1989-07-28
Abstract: PURPOSE:To miniaturize, to improve a receiving function, and to evade restriction on an installing position by winding a conductor wire spirally around a bar-shaped insulator to form an antenna. CONSTITUTION:A supporting leg 2 is attached at the nearly middle part of the bar-shaped insulator 1 so as to form nearly the whole into a T-shape. Then, the conductor wires 3, 4 are wound spirally for plural times around both sides of the insulator 1 respectively centering the supporting leg, and respective end parts 3a, 4a are made into connection terminals. Thus, since the antenna is formed by spirally winding the conductor wires 3, 4 around the bar-shaped insulator 1 for receiving, the sharpness of a resonance characteristic is reduced, and gain is raised, and therefore, the receiving function is improved compared with a rod antenna, and the antenna can be miniaturized and made compact, and simultaneously, it is never restricted on its installing place.

Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To attain accurate measurement at an ultralow distortion factor by amplifying a signal from a circuit whose output impedance is changed while distortion fluctuation is accurately suppressed. SOLUTION: An input signal Sin is adjusted by a variable resistor VR and when an output impedance is increased, an offset voltage of an operational amplifier 13a is amplified, outputted as an inverted output signal Sout and an integration signal Sc integrated by an integration device 15 is outputted to an inverting input terminal of the operational amplifier 13a and the gain is decreased.

IPC: G11B15/46
Filed: 1991-08-06
Abstract: PURPOSE:To perform stable reproduction by detecting an error and sweeping the speed so as to take it in a PLL synchronous operation without fail corresponding to the change of the recording speed. CONSTITUTION:When a clock signal 11 of a tape is within the capture range of the PLL synchronous control of a reference clock signal 12, a motor drive circuit 5 is synchronously operated by a speed command 13 from a synchronization control circuit 4. At the time of the synchronization step-out, the synchronization control circuit 4 outputs an error signal 15 and sends a speed command 16 to the drive circuit 15 from an auxiliary control circuit 7. The tape speed is sweeped at a high or low speed, and an error signal is eliminated when the clock signal of the tape enters the capture range of the PLL synchronization. The drive circuit 5 selects the speed command 13. Thus, the clock signal 11 and the reference clock signal 12 are synchronized, and the driving motor 2 is taken in the PLL synchronous operation, enabling stable reproduction.
