Title: Manufacture of lead frame
Inventor: NAGATE TAKASHI
IPC: H01L23/50
Filed: 1987-04-13
Abstract: PURPOSE:To make it possible to adopt an interdigitated structure under the state wherein commonness in sizes of pitches is kept even if the pitch is narrow, by forming a frame comprising a pattern having an intermediate shape, and cutting the pattern having the intermediate shape at an outer lead part by laser beam machining. CONSTITUTION:A die island 1, inner leads 2, a dam bar 3, guide holes 5 and the like other than outer lead parts comprise a final pattern by stamping machining or etching machining. Two outer leads, which are linked to the dam bar 3, to which the outer lead parts correspond, form a unitary body, and a pattern 4a is provided. A frame comprising the pattern 4a is formed. The guide holes 5 are used as references for positioning. The pattern 4a is cut along a broken line and separated into individual outer leads. The cutting can be performed by the laser beam machining at an interval of 0.05-0.1 mm. Therefore, an interdigitated structure can be adopted for the lead frame of an integrated circuit having, e.g., a 22-pin DIP having a pitch of 1.778.

Filed: 1986-04-16
Abstract: PURPOSE:To automatically transit the titled equipment to the acquisition and tracing with very simple constitution by providing a loop filter controlling variably a clock rate of copied code series generated from a copy code generator. CONSTITUTION:A received spread code is inputted from an input terminal 1 to a correlation device 3 and a copy code is generated at first from a copy code generator 2 and inutted to the correlation device 3.

Title: Rush current suppressing circuit
Inventor: MIYAZAKI SHOICHIRO
IPC: H02M7/12
Filed: 1988-04-13
Abstract: PURPOSE:To limit a rush current by feeding in advance a charging current to a smoothing capacitor at the time of power source interruption. CONSTITUTION:When an AC input voltage 1 is applied to turn ON an input breaker 2, an AC voltage stepped down by a transformer 3 is converted by a rectifier 4 to a DC, and smoothed by a capacitor 5. When a power source closing switch 6 is closed, a contactor 7 is operated to supply a current through a rectifier 9 and a smoothing capacitor 10 to a load resistor 16. In this case, a charging current to the capacitor 10 is fed through a resistor 19 and a diode 20 without the rectifier 9. The value of the resistor 19 in this case is selected to sufficiently smaller than the value of a discharging resistor 21. Thus, a voltage at both end voltage of the capacitor 10 becomes a normal state value after a delay time determined by the values of the resistor 19 and the capacitor 10. Thereafter, when the switch 6 is closed, the contactor 7 is operated to suppress its rush current.

Abstract: PURPOSE:To transmit an auxiliary signal while superimposing it upon a main signal with the aid of a small circuit scale by pulse interval-modulating the input waveform of the auxiliary signal, and giving the coding violation of the main signal on this interval-modulated pulse. CONSTITUTION:The input waveform of the auxiliary signal to be inputted to an input terminal 6 is pulse-interval-modulated by a modulation circuit 10, and the interval-modulated pulse (a) is outputted, and added to the main signal coding rule violation(CRV) control signal 13 of an encoding circuit 1 through a re-timing circuit 11. Then, the circuit 1 controls the coding rule of the main signal so as to give the CRV to it when the interval-modulated pulse (b) exists in its input, and so as not to give the CRV in other case. Besides, in a receiving side, the detection of the CRV is performed simultaneously with the decoding of the main signal by a decoding circuit 2, and the waveform of a CRV detection signal (d) is obtained as a CRV detection output 14. Then, pulse-interval demodulation is performed in a demodulation circuit 12 by using the signal (d), and the waveform of the auxiliary signal is regenerated. Thus, the auxiliary signal can be transmitted while being superimposed upon the main signal through the aid of the small circuit scale.

Filed: 1981-06-12
Abstract: PURPOSE:To facilitate the tuning operation for a tuning indicating device of a bar graph type which represents plural tuning points by lighting up a dot, by blinking the dot every time the tuning point varies in the tuning mode. CONSTITUTION:A channel selection display 18 informs the selection of channel by lighting up a dot with each 1MHz in the receiving mode of the FM broadcast. A dot of 76MHz glows in case a station of 76MHz is received. When a channel is selected, a PLL circuit varies the receiving frequency with a 100KHz step. The signal showing the unlocked state is delivered from a PLL circuit with each change of the receiving frequency. The dot is turned off with each output of said signal. The details can be known for the channel selection by counting the blinking numbers of the dot. Thus the receiving stations having the unit under MHz can be known.

Title: Acceleration sensor
Inventor: AWAI TAKAYOSHI
IPC: H01L29/84
Filed: 1995-04-14
Abstract: PURPOSE: To enhance the detection sensitivity of acceleration. CONSTITUTION: A silicon substrate is machine, using the technology for micromachining a semiconductor, to form a rectangular frame-like supporting part 1, two beams 2a, 2b and an overlapped part 3 integrally. The two beams 2a, 2b are supported, at one ends thereof, on the adjacent inner side faces at the supporting part 1 and bonded, at the other ends thereof, with a weight part 3 thus supporting the weight part 3 swingingly. A strain gauge 5 having resistance variable depending on the flexure of the beams 2a, 2b is mounted on the surface of the beams 2a, 2b. The two beams 2a, 2b have longitudinal center lines which do not extend in parallel with each other but intersects substantially perpendicularly.  Since the weight part 3 is supported by two beams 2a, 2b, flexure of the beams 2a 2b can be increased for same acceleration and thereby the detection sensitivity of acceleration can be enhanced. Since the two beams 2a, 2b do not extend in parallel with each other, acceleration can be detected in three axial direction.

Title: Agricultural tractor
Inventor: IMANISHI RYOZO
IPC: B60K17/348
Filed: 1993-04-16
Abstract: PURPOSE:To reduce shocks caused by clutch engagement and disengagement by providing a standard drive system clutch for a front wheel speed change devide, and using a friction clutch as a speed-increasing drive system clutch. CONSTITUTION:Since an agricultural tractor is in a straight-forwarding or a slow-turning state in which the machine body is not turned quickly when it performs high load work such as farming or trencher work, the front wheels are driven via an engagement clutch 20 allowing high torque to be transmitted. In such a case, since the travelling speed of the machine body is very slow despite a high transmitted torque, shocks caused by the engagement and disengagement of the engagament clutch 20 are relatively small. Quick turning at a ridge in a rice field does not invlove high load work, and so high torque need not be tranmitted to the front wheels. When the tractor is driven via a friction clutch 18 for a speed-increasing system, the bearing of the friction clutch 18 need not be set to a value too large to perform clutch operation.
