A microprocessor 14 controls a driver circuit 12 with a through rate control signal and an analog control signal 20. The through rate control circuit 11 supplies the through rate control signal to the driver circuit 12 as a power supply signal. When the microprocessor 14 supplies a digital control signal 16 to a digital-analog converter 18, a DAC18 converts it into an analog control signal 20 to apply it to the input terminal of the driver circuit 12. The driver circuit 12 drives PWM current in the forward and reverse directions through a coil, and conducts acceleration/deceleration in response to the current to position the reading head 24 above a rotating disc 26.

Abstract: PURPOSE: To provide a heater with a deodorizing function capable of both heating and deodorizing while neither particular deodorizing mechanism other than a heater is used nor particular energy is consumed for deodorization. CONSTITUTION: An extreme infrared radiation heater 2 is provided with a titanium oxide film 6 over the surface of a small pane of crystalized glass 4 low in heat conductivity, and a conductive film 8 is provided for its back surface.

The deodorizing capacity of ethanol is reduced in concentration from 150ppm for the initial value to 20ppm after 20 minutes have elapsed.  Judging from a fact that the titanium oxide film 6 is only formed over a pane of crystalized glass 4, the functionally deodorizing heater can thereby be provided in such a way that only an extremely simple alteration is constitutionally made, no excess energy is consumed, and a little ultra violet ray is effectively used, which comes out of a lighting fluorescent lamp and the like. In this case, noise will not be produced at all.

Title: Frequency modulator
Inventor: OWAKI TOSHIYUKI
IPC: H03C3/00
Filed: 1988-06-20
Abstract: PURPOSE:To prevent the generation of undesired radiation during the working of a frequency converter by preparing a synchronism detector to detect the phase step-out of a phase synchronizing circuit and outputting a serial data signal to a variable divider via a serial data signal generated only when the step-out is detected. CONSTITUTION:A synchronism detector 8 is set between a phase comparator 4 and a serial data signal generator 7. In this case, the detector 8 consists of an AM wave detector which is generally used. In case the error signal of a phase comparator 4 fluctuates due to the step-out, the negative voltage is taken out after the rectification carried out by a wave detecting circuit 13 consisting of the capacitors C1 and C2, a diode D1 and the resistances R1 and R2. Then the signal is outputted to the generator 7 via a buffer amplifier 12 only in a step-out state. Meanwhile the serial data signal is surely produced and then stopped after the step-out state. Thus it is possible to exclude the disturbance signal mixed into the input signal and to prevent the undesired radiation.

Title: Semiconductor light emitting device
Inventor: KAMITE KIYOTSUGU
IPC: H01S5/06
Filed: 1988-06-20
Abstract: PURPOSE:To obtain light pulses characterized by no chirping and an excellent extinction ratio by injecting a second single-mode laser beam into the active layer of a first single-mode laser, modulating the laser with current pulses, separating the modulated light, and obtaining the signal light. CONSTITUTION:The oscillating output of a first single-mode laser DFB 12 generates a light pulse having relaxation oscillation at the rise-up of the pulse. The wavelength is changed, and the distribution of chirping gain due to the fluctuation of a carrier is also changed. Therefore, the light of a second single- mode laser DFB 10 which is injected into the laser 12 is affected by the gain distribution. The light is amplified, and the waveform is modulated. The modulated light of the laser 10 receives a gain in an active layer but hardly receives the effect of the wavelength change due to the change in refractive index. Therefore, relaxation oscillation appears in intensity, but chirping hardly occurs. Thus, the light pulses characterized by no chirping and an excellent extinction ratio is obtained, and the transmission characteristics can be improved.
