Title: Semiconductor relay circuit
Inventor: ARAKAWA MASAO
IPC: H03K17/567
Filed: 1986-01-25
Abstract: PURPOSE:To realize a semiconductor relay circuit which can execute switching at a high speed, by a simple circuit constitution, by providing a control circuit for executing quickly charge and discharge of a control voltage of a switching element. CONSTITUTION:A MOSFET of an enhancement type is used as a switching element 7. A pair of transistors TR 4 are connected so as to become a thyristor structure, therefore, two TRs become a state that a positive feedback has been applied to each other, and a positive charge which has been accumulated in a gate of the FET 7 is discharged quickly. When an absolute value of a threshold voltage VTH of the FET 7 is set in advance to a voltage drop VS or above in a conducting state of the pair of TRs 4, the FET 7 becomes a non-conducting state quickly together with a charge of a gate terminal, and a relay also becomes off. In this way, the gate terminal of the FET 7 is charged quickly, and also, the accumulated charge can be discharged quickly.

Title: Adaptive antenna
Inventor: KAWABATA KAZUAKI
IPC: H01Q3/26
Filed: 1986-01-28
Abstract: PURPOSE:To obtain a constitution which is strong against the variation of temperature and has a high reliability, by inserting the second weight circuit between a reference signal generating part and a difference circuit to prevent the degradation in a desired output signal in the wide dynamic range of a desired input signal. CONSTITUTION:The second weight circuit 17 is inserted between a difference circuit 15 and a reference signal generating part 14. The second correlation processing circuit 18 operates correlations between the output signal of the difference circuit and a reference signal to determine such weighting that a desired signal much correlated to the reference signal in the output signal of the difference circuit is suppressed. The second weight circuit 17 adjusts the amplitude and the phase of the reference signal automatically. Since a desired signal component in the output terminal of the difference circuit 15 is suppressed, the first weight circuit 12 and the first correlation processing part 16 do not respond to the desired signal component at all to prevent the loss of the desired signal.

Title: Centrifugal load tester
Inventor: KONNO TAKAO
IPC: G01M99/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To enlarge a rotary arm by making the space, defined by the rotary arm and a lower disc, narrower as an oscillatory frame ascends through increase of r.p.m. of the rotary arm until a predetermined r.p.m. is reached. SOLUTION: A driving force is transmitted from a driver 1 through a bevel shaft 3 and a transmission 2 to a rotary shaft 4 which then turns a rotary arm 6. When a centrifugal force is applied to an oscillatory frame 7 through rotation of the rotary arm 6, a sample case 9 ascends in proportion to increase in the r.p.m. of rotary arm 6 around a pin fulcrum 8 and a centrifugal acceleration is applied in the circumferential direction to the base of the case 9. Air in a pit 10 turns as the rotary arm 6 turns to produce windage loss resistance. A lower disc 10b is supported by a plurality of servo jacks 12 and lifted through the jack 12 such that the lower space of rotary arm 6 is made narrower as the r.p.m. of rotary arm 6 increases until a predetermined r.p.m. is reached.  This structure reduces the frictional force of air on the side face of pit 10a and facilitates the lengthening of rotary arm 6.

Title: Electron ray resist having two-layered structure
Inventor: KAWASAKI YOKO
IPC: G03F7/038
Filed: 1987-01-27
Abstract: PURPOSE:To prevent generation of charge-up and to improve the accuracy of a pattern by imparting electrical conductivity to the lower resist of a resist having two-layered structure. CONSTITUTION:The electrical conductivity is imparted to the lower layer resist, i.e., flattening layer, of the electron ray resist having the two-layered structure. The electrical conductivity is imparted thereto preferably by using an electric charge transfer active material, for example, hydrazone deriv. Such hydrazone deriv. is preferably p-dimethylaminobenzaldehyde(diphenyl hydrazone), p- diethylaminobenzaldehyde(diphenyl hydrazone), p-diethylaminobenzaldehyde(benzylphenyl hydrazone), etc. Since the electrical conductivity is imparted to the lower resist layer in such a manner, the charge-up by electron rays at the time of electron ray exposing is prevented and the resist pattern having no positional serration is obtd. The pattern accuracy is thereby enhanced.

Title: Manufacture of clad steel sheet
Inventor: WATABE YOSHIYUKI
IPC: B23K20/04
Filed: 1993-02-02
Abstract: PURPOSE:To reduce the non-unifomity in the thickness of a clading mateial and camber and to satisfy the severe tolerance of thickness by providing dummy parts having specified thickness in the tip and rear end parts in the rolling direction of the original steel sheet of base material and both side face parts and executing hot rolling by putting a material having larger thermal deformation resistance of the original steel sheet of base material and the original sheet of clading material underside. CONSTITUTION:In the case that the high temp. deformation resistance of the original sheet 1 of clading material which composes a composite is larger than that of the original steel sheet 2 of base material, the clad part 8 of the composite becomes the state of underward camber with screw-down and that state is continued until the dummy part 4 is brought into contact with a stopper guide 6 or a roller table 7. When the dummy part 4 is brought into contact with the stopper guide 6 or the roller table 7, the composite is screwed down in the state that a reaction force is restrained after this time by receiving the reaction force with the dummy part. Consequently, non- uniformity in the thickness of the clading material in the tip and rear end parts due to downward camber at the time of rolling is reduced. And, the dummy part 4 is taken as a thickness of 30-100% of the original steel sheet of base material which is projected by >=500mm.

Title: Ultrasonic probe
Inventor: SHIMODAIRA TAKAYUKI
IPC: G01N29/04
Filed: 1988-01-28
Abstract: PURPOSE:To obtain an ultrasonic probe which is allowed to eliminates the use of a lens, by arranging a soft sheet member having a plurality of piezoelectric elements buried in an array to be curved at a specified curvature along the array direction thereof. CONSTITUTION:A number of piezoelectric elements P buried into a sheet member 5 are arrayed in a train and insulated from one another with a plate body 6. The plate body 6 is made of a flexible material so as to be curved at a desired curvature and bonded on a packing material 1. With such an arrangement, ultrasonic waves radiated simultaneously from the piezoelectric elements P arranged in the circumferential direction are gathered in the max. amplitude at a specified position, which provides an action the same as that obtained when a lens is used. This eliminates the need of using a lens thereby enabling the building of an ultrasonic probe in a small size along with a reduction in the attenuation thereof. This also gets rid of reflection with a lens otherwise causing overlap with a signal at a defect part thereby preventing overlooking of the defect part.
