Title: Speed control circuit for dc motor
Inventor: KURITA YUKINOBU
IPC: H02P7/288
Filed: 1990-01-16
Abstract: PURPOSE:To protect an IC from breakdown even when a power supply is connected with incorrect polarity by connecting a diode having negative temperature coefficient in forward direction from the source terminal of a motor to the output terminal of the IC. CONSTITUTION:A DC motor M is connected between the source terminal Vo of a motor control IC 1 and a terminal (4), while a torque control resistor Rt and a speed regulation resistor Rs are connected between terminals (1), (3) and (3), (4). A diode 2 having negative temperature coefficient is connected between the source terminal Vo connected with + side of a power supply and the terminal (1) in forward direction toward the terminal (1). When the terminals Vo and (2) are connected with incorrect polarity, the diode 2 blocks excessive current flow to the terminal (1) thus blocking current flow from the terminals (3), (4) to (1). Consequently, the IC is protected and temperature fluctuation of flux of a driving magnet is cancelled.

Title: Measurement for depth of cracking
Inventor: HIRONO SUSUMU
IPC: G01B17/00
Filed: 1987-01-14
Abstract: PURPOSE:To measure the depth of cracking accurately, by gradually expanding the distances of an oscillating element and an oscillation receiving element from the cracking as set at a symmetrical position with respect to the cracking to determine a distance at which an initial phase of a propagation waveform is inverted. CONSTITUTION:An oscillating element T and an oscillation receiving element R connected to an ultrasonic speed measuring device 1 are set at a symmetrical position with respect to a cracking C on the outer surface of a sample A. Then, a pulse waveform voltage of 10kHz is applied to the oscillating element T to generate an ultrasonic wave and the ultrasonic wave propagating through the sample A is detected with the oscillation receiving element R to be converted into a propagation signal, which is sent to an amplifier 2 to amplify while being passed through a band pass filter. The signal is converted into digital from analog with a transient memory 3 and displayed on an oscilloscope 5 via a waveform processor 4. As distances (a) to the oscillating element T and the oscillation receiving element R from the center of the cracking are expanded gradually, the initial phase of the propagation waveform is inverted downward as shown by the arrow (y) from upward as shown by the arrow (x) when the distances (a) exceed the depth of the cracking C, thereby enabling measurement of the depth of the cracking.

Title: Copper alloy for lead frame of integrated circuit with excellent hot workability
Inventor: MURAKADO HIROSHI
IPC: H01L23/48
Filed: 1982-01-20
Abstract: PURPOSE:To provide excellent hot workability such as higher than 130 of microvickers hardness, higher than 5% of elongtion, and higher than 50% of IACS of conductivity by containing 3.0-3.5wt% of Ni, 0.5-0.9wt% of Si, 4:1-6:1 of weight ratio of Ni:Si and 0.01-0.1wt% of Mn and substantially the residue of Cu. CONSTITUTION:When the weight ratio of Ni:Si is not in the range of 4:1-6:1, preferable intermetallic compound cannot be obtained, and it does not satisfy the required characteristics as the lead frame of an integrated circuit at the points of tensile strength, the relationship between elongation and hardness, heat resistance, and conductivity. Even when the Mn is less than 0.01wt% in the range that 3.0-3.5wt% of Ni and 0.5-0.9wt% of Si, it can satisfy the characteristics as the material for the lead frame of an integrated circuit, but its elongation value at high temperature is low with brittleness. Accordingly, a crack occurs at the hot working time, the yield is decreased. When the Mn exceeds more than 0.06wt%, the hot workability is excellent, but the conductivity becomes less than 50% of IACS, which does not satisfy the required characteristic.

IPC: H04B1/46
Filed: 1995-01-23
Abstract: PURPOSE: To make transmission reception changeover operation stable for a radio equipment by feeding back an output of a detection smoothing circuit to an amplifier to control the gain of the amplifier. CONSTITUTION: A voice signal outputted from a microphone 1 is amplified by an amplifier 2 and its output is detected and smoothed by a detection smoothing circuit 3. A detection output is fed back to the amplifier 2 to conduct AGC and fed to an A/D converter 4, and when an output level of the A/D converter 4. When an output level of the A/D converter 4 exceeds a preset reference level, a CPU 5 closes a power switch 8 to select a voice switch 6 and an antenna multicoupler 9 to change the reception state into the transmission state. Since the gain is controlled by the AGC and an output of the A/D converter is compared with a reference level, the operation is more stable than the case with comparison with a detection voltage in a conventional equipment. Since the detection smoothing circuit 3 is used in common as part of the AGC feedback circuit, the cost increase is suppressed.

Filed: 1984-01-23
Abstract: PURPOSE:To suppress the combustibility and deformation of a plastic tube by winding a plastic tube which has a high elasticity modulus and a low coefficient of linear expansion as the secondary coating layer of a single core cable with a flame-resistant tape by pressing. CONSTITUTION:This cable is provided with an optical fiber 1, primary coating layer with a low elastic modulus, air layer 3, secondary coating layer 4 which is increased in high elastic modules and decreased in coefficient of linear expansion by being heated dielectrically and drawn, flame-resistant tape 5, and plastic sheath 6. The secondary coating layer 4 protects the optical fiber 1 and serves as a tensile strength material and a compressive material against mechanical strength which operates on the cable lengthwise. Further, there is the air layer 3 formed between the primary coating layer 2 and secondary coating layer 4, so the secondary coating layer 4 becomes flat to lateral pressure and collapses eventually. An increase in tube diameter at right angles to the lateral pressure is suppressed to increase greatly the lateral pressure at which the collapse occurs.

This instruction is received at an instruction register IR30. Then a machine word received at an IR30 is interpreted by an instruction decoder 40 to produce various control signals in a prescribed timing respectively.

Title: Nonvolatile semiconductor storage
Inventor: YAMAGATA YASUJI
IPC: G11C16/06
Filed: 1993-01-22
Abstract: PURPOSE:To prevent the destruction of other storage data and the movement to a depression type at a writing time by providing a reference transistor having a floating gate formed by the same kind, the same process as a MOS transistor forming a memory cell. CONSTITUTION:A current voltage Vp and a bit line selection signal Vb are made high voltage at a writing time. Thus, a reference transistor (Tr) Qr is turned on, and a fixed current I flows through between a drain electrode and a source electrode, and a resistor R1. Thus, the voltage decided by the load characteristic of the Tr Q1 is supplied to the drains of memory cells M1-M3 through a node N1. Then, when the gate lengths of the cells M1-M3 are short, the gate lengths of the cells and the Tr Qr become short as well because of the production by the same process. Then, the voltage-current characteristic at the point N1 is shifted in the direction of low voltage as well since the on current I of the Tr Q1 is increased, and becomes lower than the gate electrode potential of the Tr Q1. Thus, the destruction of the storage data and the movement to the depression type in the memory cells are prevented since the voltage impressed to the drain electrode of the memory cell is reduced.
