Title: Manufacture of work fluid recirculated type differential engine
Inventor: YONEDA SHIN
IPC: F03C1/00
Filed: 1981-03-31
Abstract: PURPOSE:To generate differential thrust, by a method wherein a propelling cylinder and an auxiliary cylinder are carranged such that the thrusts of both cylinders are in opposite direction and equal pressure, and neutralizing cylinders are arranged in a balanced manner, having a work fluid recirculating circuit opposite to the direction of the thrust of the auxiliary cylinder. CONSTITUTION:When a pressurizing circuit 3 for producing forward movement is pressurized equally, thrusts are produced in respective cylinders 5-8 in directions shown in the drawing. Here, the thrust produced in the auxiliary cylinder 6 is neutralized by reverse thrusts produced in neutralizing cylinders 7, 8, so that the thrust is zero at the point of a piston shaft 9 where the thrusts are acted. Therefore, only the propelling cylinder 5 begins to move in forward direction 10 with almost no resistance being acted thereto. In order to continue the movement of the propelling cylinder 5, it is necessary to feed work fluid under pressure. However, since work fluid in the auxiliary cylinder 6 associated with the propelling cylinder 5 is forced out by a piston in the cylinder 6 and the cylinder 5 is replenished with work fluid recirculated from the cylinder 6, movement of the cylinder 5 can be continued with no need of feeding work fluid from a pressure source.

Title: Defect inspector
Inventor: MORIOKA YOSHIHISA
IPC: G01N21/89
Filed: 1987-03-04
Abstract: PURPOSE:To achieve a higher reliability, by inspecting a defect of an object to be inspected based on electrical signal from a dead zone on the scanning starting side to that on the scanning ending side. CONSTITUTION:Beam light 3 from a beam light source 2 scans the surface of an object 1 to be inspected in the direction of the arrow alpha with a rotary mirror 4 and the transmission light 5 is converted into an electrical signal through an optical lens 6 and a photoelectric converter 7 to be supplied to a waveform shaping circuit 21. When a plate width of the object 1 being inspected is within a scanning width for the converter 7, an output signal of the circuit 21 brings forth a pulse waveform 2' by a transmission light to an edge part on the scanning starting side of the object 1 being inspected from the initial end of a light scanning width and a pulse waveform 3' by a transmission light from an edge part on the scanning ending side of the object 1 being inspected to a light scanning ending end in addition to a pulse waveform 1' by a transmission light from a defect. But the waveform 2' is suppressed by a rising dead zone signal L outputted from a rise FF 33 while the waveform 3' is suppressed by a falling dead zone signal outputted from a fall FF 29. As a result, the waveform 1' only generated from the object 1 being inspected is extracted from a logical gate 22 thereby enabling determination with respect to a defect.

IPC: H01H13/00
Filed: 1991-02-21
Abstract: PURPOSE:To reduce an optical loss and make an adjusting work on the switching member of a photopath needless by guiding light incident from the input side through a photoconductor to the output side and switching the photopath in the interval thereof by a switching plate going in and out of the slit of the photoconductor. CONSTITUTION:When a photosignal is incident from optical fibers 2 on the input side, light is incident on a photoconcuctor 9 from the end face 9a to turn back along a photopath so as to be 9a incident again on the output side from the end face. At this time, light passing through a slit 13 goes through an angular window 14a so that a switch 1 may be set in ON state without being hindered by a switch plate 14. Next, when an actuator 22 is pushed in the left direction, a movable plate 15 is reversely curved to move the switch plate 14 and a shielding part 14b cuts the photopath so as to turn the switch in OFF state. In this way, by switching the photopath by simple operation of the switch plate going in and out of the slit of a photoconductor, an optical loss is reduced so as to make an adjusting work on a member for switching the photopath needless.

IPC: H04L27/06
Filed: 1980-04-15
Abstract: PURPOSE:To ensure quick extraction of a carrier wave stabilized in phase, by discriminating settlement of the phase synchronism of PLL and then supplying the nonmodulated part to the PLL as the reference signal set-up of synchronism, in case of extracting carrier wave out of the amplitude modulated wave signal containing a nonmodulated part of which envelope level is constant. CONSTITUTION:The TV modulated wave signal is converted into an IF signal through the turner 2 and then applied to the amplifier 4 and carrier wave extracting circuit 3. The signal applied to the circuit 3 is separated to be applied to the limiter 8 and nonmodulated part extracting circuit 9 respectively. The nonmodulated part comparing circuit 12 in the circuit 9 compares the level of envelope curve with the prescribed reference level, and the part exceeding the reference level is extracted as a nonmodulated part through an gated amplifier 11. At the same time, the phase synchronism of the phase synchronous circuit 17 is decided by the synchronism deciding circuit 18. The output of the limiter 8 is applied to the multiplier 5 via the switch circuit 16 before settlement of synchronism, and the nonmodulated part extracted out of the modulated signal is applied to the multiplier 5 after. settlement of synchronism. Thus a carrier wave having a stable phase is extracted in a short time.

IPC: H01L23/48
Filed: 1985-03-14
Abstract: PURPOSE:To enable the simultaneous formation of a bump at the tip of a finger by a method wherein a non-resist part of small area is provided and the current density of this resist part is increased according to the degree of progress of electroforming so as to form a metal layer to be thicker. CONSTITUTION:A resist layer 12 is removed after electroforming, and next a cut piece 10 having closed a window part containing a device hole 9 is pulled down. Then a lead frame 7 is formed on a synthetic resin film 8. Since the electroconductive metal layer 10 is merely thick enough to secure conductivity for electroforming, in this case, only a small force is needed for pulling down, and therefore this does not deform the lead frame 13. while the lead frame 7 is formed on the synthetic resin film 8, an electroconductive stainless metal film or the like can be used also in place of the synthetic resin film 8. By this method, a bump can be formed simultaneously with the electroforming of a lead frame, the forming of a lead frame with a bump is thereby facilitated, and it turns easy to conduct the work of connecting the bump and an electrode of a semiconductor chip together as well.
