Title: Signal output circuit
Inventor: MASAGAKI TOSHIHIRO
IPC: H03F1/42
Filed: 1983-09-26
Abstract: PURPOSE:To make a reverse bias voltage applied to both transistors (TR) equal to a base-emitter voltage of the TRs by connecting a base-emitter circuit of the two TRs in anti-parallel between output points of two signals. CONSTITUTION:When a signal current source 2 is conducted, an ouptut is produced at a point A, a signal current source 3 is interrupted and no output is generated at a point B, then a TR4 acts like an emitter follower and a resistor 6 is its emitter resitance. Thus, a signal outputted to the point A from the signal current source 2 is outputted to a terminal 9 through emitter follower TRs 4, 7 by using a resistor 5 as an output load. A reverse bias voltage is applied between the base and emitter of the TR11 in this case and the TR11 is cut off, but the reverse bias voltage becomes equal to the base-emitter forward voltage VBE of the TR4.

Title: Fuel supplying device for internal-combustion engine
Inventor: YAMAMOTO TADAHIRO
IPC: F02M7/17
Filed: 1983-09-26
Abstract: PURPOSE:To keep] air-fuel ratio in constant at all times by a method wherein an airflow speed is kept in constant by a variable venturi and the fuel is controlled by a pressure difference between before and after a fuel nozzle. CONSTITUTION:A variable venturi type piston 15 is arranged at the upstream of a throttle valve 14 and the piston moves up-and-down in accordance with the flow amount of air so as to maintain the air of a constant flow speed at the bottom surface of the piston at all times. The fuel nozzle 25 is arranged so as to oppose to the lower end of the piston 15 and is provided with a valve body 35 to change the opening area of the nozzle. The valve body 35 is operated by a diaphragm 34 and the upper chamber 42 of the diaphragm 34 is communicated with a hole 28, introducing a venturi pressure at the downstream of the nozzle 25, while the lower chamber 40 is communicated with the hole 27, introducing the venturi pressure at the downstream of the nozzle 25. When the amount of fuel injected from the nozzle 25 is increased, the speed of the jet stream of the fuel in the stream of air is increased and, therefore, the pressure is reduced and the pressure difference between the pressure of the hole 28 and the same of the hole 27 becomes lower than a given pressure difference. Accordingly, the valve body 35 moves upward due to the pressure reduction of the chamber 42 to reduce the amount of fuel and, therefore, the air-fuel ratio may be kept in constant at all times.

Title: Three-dimensional measuring machine
Inventor: SHIZURI AKIHIKO
IPC: G01B21/20
Filed: 1984-08-27
Abstract: PURPOSE:To prevent a Z axis structure from falling securely in safety by providing an abnormality detecting valve device which cut off supply air to a cylinder device when the pressure in the cylinder of an air balance device drops by a specific value and inserts a lock pin into either lock hole of a lock member with the energizing force of a spring. CONSTITUTION:The total weight of members which constitute a Z-axis structure 6 is balanced with the air pressure of the cylinder 19. If the pressure in the cylinder 19 of the air balance device 17 drops by the specific value, the abnormality detecting valve device 61 releases a cylinder device 53 to insert the lock pin 52 into either lock hole 42 of the lock member 41 through the operation of the spring 54. Consequently, the relative simple constitution which uses only the air circuit prevents the Z-axis structure 6 from falling owing to the pressure drop in the cylinder 19.

Filed: 1989-07-12
Abstract: PURPOSE:To easily bend only the top edge part of an angle part according to necessity by constituting the title mechanism so that only the top edge part of the angle part is bent during the time when a regulating means is in operation, while the whole angle part is curved when the regulating means is released.

IPC: H03B5/12
Filed: 1988-07-15
Abstract: PURPOSE: To prevent the bandwidth from being reduced owing to a parasitic circuit element by connecting the output terminal of an operational amplifier to the output terminal of a regulator, connecting the current input terminal of a 1st voltage-controlled current source to a 3rd potential, and further connecting its current output terminal to a 1st circuit node. CONSTITUTION: The ratio of the current of a 1st constant current source I4 and the current of a 2nd constant current source I5 determines a regulating direction. The regulating direction is inverted by replacing an operational amplifier UP input terminal. A separating amplifier TA is provided so as to coupled a low-resistance regulator input terminal ER with a 1st oscillator and amplifier input terminal A1 with high resistance. A minimum signal passing time and considerably large bandwidth in a high-frequency part of the circuit are obtained by deleting parasitic capacitance within the range of the base terminal of a differential amplifier transistor.  Then the operation of noise of a regulating loop to an oscillator output signal is minimized by 4th capacitance of corresponding size connecting the control input terminal of the voltage-controlled current source to a reference potential.

Title: Mold for cutting and shaping semiconductor
Inventor: KARUBE TETSUO
IPC: B21D53/00
Filed: 1988-07-19
Abstract: PURPOSE:To prevent adhesion of residual solder and to stabilize pressure exerted to leads during shaping of the leads for preventing deviation or deformation of the leads for realizing highly precise lead shaping by providing a groove in each part where a lead comes into contact on the surface of a bending punch or of a bending die. CONSTITUTION:A resin sealed part of a semiconductor package 14 is inserted in a guide hole 12b to be engaged thereby and leads 13 of the lead frame of the semiconductor package 14 are arranged on the top face of a cutting and bending mold 13 across the top face of a guide section 12a. Then, a punch 11 for cutting and bending the leads is pressed down so that the leads 13 are cut into a predetermined length while they are shaped into predetermined configurations by the lead cutting/bending punch 11 and the bending die section 12c. Since grooves 12d are formed at the center of the regions on the surface of the bending die section 12c where the leads 13 come into contact, no residual solder is deposited there and, therefore, the leads 12 are always subjected to stable pressure during the shaping process. Accordingly, the dimensional precision can be improved since the leads 13 can be prevented from being deviated and hence from being deformed.
