Title: Variable gain amplifier circuit
Inventor: SATO HIDEO
IPC: H03G3/10
Filed: 1985-04-17
Abstract: PURPOSE:To realize a wide-band variable gain amplifier which operates with a low voltage power source by connecting emitters of a differential couple which constitute a variable transformer conductance type multiplying circuit to an input terminal by a resistance. CONSTITUTION:Input terminals 500 and 600 are connected to the base electrodes of transistors (TR) 51 and 52 of a voltage current converter 5. Constant current sources 50 and 60 are connected to the emitter electrodes of the TRs 51 and 52 and a resistance 53 is connected between the emitter electrodes. The emitter potentials of the 1st and the 2nd differential couples 1 and 2 can be lowered down to a limit (about 1V) where the constant current sources can operate. Further, the base voltage of the differential couples is used as a gain control signal, so the amplification form of the input signal is different from those of an emitter follower circuit and a common base amplifier circuit, so that this circuit suits to a wide band.

Title: Semiconductor switching device
Inventor: TSUBAKI KOTARO
IPC: H01L29/68
Filed: 1989-03-31
Abstract: PURPOSE:To simultaneously obtain switching functions of two circuits in a reverse relation by one control voltage for a semiconductor switching device by not substantially supplying a current to a first DC load from a DC power source and supplying a current to a second DC load. CONSTITUTION:When a control voltage to be applied to a control electrode layer 7 becomes a predetermined value, an electron wave is diffracted in the process of propagating in an electron storage layer 21 from a semiconductor layer 11 side for a first electrode to a semiconductor layer 13 side for a second electrode, and the wave reaches a semiconductor layer 13 for a third electrode. Accordingly, the wave to be propagated to the layer 12 is diffracted by a surface superlattice layer 3 to reach the layer 13. Thus, a current I2 can be supplied only to a DC load L2 without substantially supplying a current I1 to a DC load L2 from a DC power source 31. Thus, switching functions of two circuits can be simultaneously obtained in a reverse relation by one control voltage VC.

Title: Trigger device for nailing machine
Inventor: OSUGA TATSU
IPC: B25C1/00
Filed: 1995-04-05
Abstract: PURPOSE: To prevent a nail from being shot by mistake when the nailing machine is moved to a position to be nailed. CONSTITUTION: A main directional control valve 15 actuating a nailing machine is controlled to be opened/closed by an solenoid valve 17. Switches 20 and 21 detecting the operations of a trigger lever 5 and a contact arm 7, are connected to a control device 19. The timer 23 of the control device 19 starts counting upon receiving an ON signal for the trigger switch 20. When a state where the trigger switch 20 is turned on, and the contact switch 21 is turned off, is kept on for a specified period of time, the control device 19 suspends the output of current driving the solenoid valve 17. When the contact switch 21 is turned on within a specified time, the control device 19 outputs current driving the solenoid valve 17, and drives the solenoid valve 17 so as to allow a nail to be shot.  Since no nail will be shot at all even if the contact arm 7 is brought into contact with substances around the machine when the machine with the trigger lever left as is actuated, is moved around and the like, safety is thereby enhanced.

Title: Simplified reinforcing method for asbestos cement pipe
Inventor: ICHIKAWA MINORU
IPC: F16L9/08
Filed: 1995-03-13
Abstract: PURPOSE: To provide a method which simplifiedly reinforces an asbestos cement pipe without using material being large in specific gravity such as a metal pipe and concrete in the case of reinforcing and restoring an asbestos cement pipe. CONSTITUTION: Since the outer periphery of an asbestos cement pipe 1 is unitedly covered by the covered pipe 2 of fiber reinforced plastics whose elastic modulus (Youngs modulus) is the same as or more than the elastic modulus (Youngs modulus) of the asbestos cement pipe 1 itself, the weight of the covered pipe 2 is about one fifth in comparison with the weight of an iron pipe being the same in thickness, and a divided covered pipe 2' can be very simply attached by a few workers. In addition, since after covering the covered pipe 2 on the asbestos cement pipe 1, adhesive resin agent is filled from a fixed filling port into a gap between the asbestos cement pipe 1 and the covered pipe 2, both the pipes 1, 2 are united, and therefore can sufficiently oppose to an outer load and pressure inside a pipe.

Title: Roll for molten metal plating bath
Inventor: TAKEYA YOSABURO
IPC: C23C2/00
Filed: 1995-03-14
Abstract: PURPOSE: To prevent generation of slippage and sink roll marks by making only an irregular rough surface serve as a roll outer periphery brought into contact with a steel strip, and specifying its roughness. CONSTITUTION: Only an irregular rough surface is made to serve as a roll outer periphery brought into contact with a steel strip, provided that its roughness exceeds Rmax 150μm and is less than Rmax 500μm. A covering layer of fluoride, carbide or oxide, or these cermet material. For forming roughness, any of cutting, rolling, electric discharge machining and grid blasting or combination of these can be applied. By employing only roughness higher than the size of foreign matter in a plating bath, no slippage occurs even at a steel strip driving speed of 100 m/min, so it is possible to attain a plated surface with no sink roll marks. It is also possible to restrain surface roughness from changing with formation of the covering layer, thus increasing the service life of the roll.

The pipe NP on the front side of the joint FJ on the cutting face side is adapted to slide backward, thereby joining the pipe on the front side of the joint FJ on the cutting face side with the newly installed pipe NP and the pipe on the rear side of the joint on the cutting face side respectively. At the same time, the joint on the cutting face side and a new joint are inserted into either the pipe on the front side of the joints on the cutting face side or the newly installed pipe and the pipe on the rear side of the joint on the cutting face side. The joint on the cutting face side and a new joint are adapted to slide to a pipe joint position and then clamped.

Title: Inspection of pattern
Inventor: MASUDA TATSUNOSUKE
IPC: G01N21/93
Filed: 1983-05-11
Abstract: PURPOSE:To improve the efficiency of inspection by excluding the part having no problems if there is dissidence with a standard pattern. CONSTITUTION:The images on respective one scanning line 18, 18' on a base plate 5 having a standard pattern and a base plate 6 to be inspected are projected and imaged by lenses 15, 15' onto line image sensors 16, 17.

Title: Manufacture of liquid crystal element
Inventor: OIBE KEI
IPC: G02F1/1337
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To align or re-align liquid crystal in a desired alignment state by operating a cooling control of a substrate surface correspondingly to an alignment limiting force of the liquid crystal which each substrate surface in contact with the liquid crystal has. SOLUTION: A liquid crystal element 4 is placed on a holding member 2 in an atmosphere control tank 1. Next, the liquid crystal of the liquid crystal element 4 is heated to the transition temperature or above by a furnace and a temperature controller 3 prepared in the atmosphere control tank 1. Following this, the liquid crystal element 4 is cooled down at a specified cooling rate from the substrate side via the holding member 2 by the temperature control device 3. When the liquid crystal element is cooled down, the domain of the liquid crystal can be controlled in the size and the number by performing the cooling by adjusting the conditions like a temperature gradient, a cooling rate, etc., considering a difference in the alignment limiting force between both substrates of the liquid crystal element. Moreover, it becomes unnecessary to drastically change the cooling rate at the time of re-aligning the liquid crystal, and the conditions for the cooling rate are improved and the cooling control also becomes easier.
