Title: Buzzer driving device
Inventor: NAGASOE KAZUFUMI
IPC: G10K9/12
Filed: 1993-09-27
Abstract: PURPOSE:To secure the ringing time of a buzzer without using a capacitor large in capacity by keeping a time interval from a time to generate an operation signal by a switch means to a time to invert the output of a frequency division means. CONSTITUTION:A frequency divider circuit 3 which frequency-divides the output of an oscillation circuit 2 is provided, and the ringing time of the buzzer BZ can be secured by the frequency divider circuit 3. In other words, when the operation signal is generated by the operation of a switch part 1, the buzzer BZ is rung by setting a latch circuit 4 and starting the operation of the oscillation circuit 2, and after that, the oscillation circuit 2 can continue to operate by latching the output of the latch circuit 4 even when the operation signal is stopped. In such a case, since the output of the oscillation circuit 2 is frequency-divided, the output of the frequency divider circuit 3 is inverted after a time regulated by a frequency division ratio from the start-up of the oscillation circuit 2 elapses, then, the latch circuit 4 is reset. In other words, the oscillation circuit 2 is stopped, then, it is restored to an original state.

IPC: A61B17/00
Filed: 1993-09-01
Abstract: PURPOSE:To provide a needle capable of easily penetrating into a head skin without resistance, safely suppressing the pain and bleeding of a patient and eliminating the horizontal part of the artificial hair in subcutaneous tissue by cutting the end of a bar-shaped body with a nearly circular cross section to form a bifurcated shape and diagonally cutting the bar so that the bifurcated parts form the shape of peaks. CONSTITUTION:This needle for planting hair is formed in such a way that; a cut face 5 is formed by cutting the tip of a stainless steel needle body 10 with a circular cross section so as to shape a U-cut part 2, and both sides of the needle body are cut off diagonally respectively to form bifurcated edges 4 in the shape of peaks to form diagonal cut faces 3. As a result of cutting both sides of the needle diagonally to form the bifurcated edges 4 with the shape of peaks and to form diagonal faces 3, the needle as a whole becomes sharper than conventional needles with evidently smaller surface area of the cut face 5. Thus, the needle can easily penetrate a head skin with lower resistance, and the pain and bleeding of patients can be safely suppressed.

Title: Processing circuit of magnetoresistance revolution-speed sensor
Inventor: YURUGEN KOOTSU
IPC: G01P3/48
Filed: 1991-09-20
Abstract: PURPOSE: To suppress an offset and to compensate a temperature and a source voltage variation and the expansion of the permissibility of component elements by arranging a means, which applies a hysteresis signal symmetrically, a preamplifier, and an offset amplifier preceding comparator inputs. CONSTITUTION: As a result of the high input resistance of a preamplifier 15, a sensor 13 is notloaded, and its characteristics are therefore not corrected. Because of the low-resistance output of the preamplifier 15, characteristics of a subsequent comparator 11 are not corrected either. With a sensor signal, an offset signal generated by an offset network 21 reaches the input of an offset amplifier 18 having the same characteristics with the preamplifier 15. If a drift in a source voltage 14, a temperature drift, and the allowance of individual elements of the preamplifier 15 and offset amplifier 18 have extents, their output signals vary in similar manner. The subsequent comparator 11 evaluates only a difference signal, so their variations are mutually compensated.

Title: Speed detector
Inventor: NAKAMURA HIROYUKI
IPC: G01S7/527
Filed: 1990-09-12
Abstract: PURPOSE:To enable accurate detection of a speed by a method wherein the strength of a diffused reflection wave from a road surface is corrected by the strength of a regular reflection wave and thereby kept to be a prescribed strength. CONSTITUTION:A transmitter 21 transmits an ultrasonic wave vertically onto a road surface 100 and a receiver 23 converts a regular reflection wave reflected in the vertical direction into an electric signal and gives it to an amplifier circuit 80. Next, the circuit 80 amplifies this electric signal, i.e., a regular reflection signal, and a detection circuit 90 detects the strength G of this regular reflection signal, and based on the strength G, sets the amplification (the amplification of a diffused reflection signal given from a preamplifier circuit 30) of a programmable amplifier circuit 40. The strength of the diffused reflection signal after amplified is kept to be fixed substantially and a signal of the strength fixed substantially is given to a wave-shaping circuit 50. During the running on a bad road having much unevenness, for instance, the strength of the regular reflection signal becomes small, the amplification of the circuit 40 is set to be small and the strength of the diffused reflection signal after amplified is kept at a fixed value substantially. Accordingly, the diffused reflection signal fixed substantially is given to the circuit 50, a count value by a frequency counter 60 is always a correct frequency value and thus a correct vehicle speed can be determined.
