Title: Fuse tube for cylindrical cutout
Inventor: NAGASE MITSUYOSHI
IPC: H01H85/042
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a fuse tube capable of reducing a manufacturing cost. SOLUTION: The necessity for cutting work an insulated tube 11 over a long distance, and forming a different level surface contacting the inside end surface of a lower part electrode 72 can be eliminated, by mounting a ring 13 on the outer peripheral surface of the insulated tube 11 to regulate the downward movement of the insulated tube 11 due to the contact between the end surface of the ring 13 and the inside end surface of the electrode 72. This can shorten a cutting work time, and can prevent the waste of material, thus can reduce a manufacturing cost.

Filed: 1991-04-08
Abstract: PURPOSE:To improve the mass productivity of a semiconductor device by depositing a metallic film for wiring on a semiconductor substrate and forming a desired wiring pattern by selectively etching the metallic film. CONSTITUTION:Connection ports 6a and 6b for leading out are respectively formed on a P- and N-type diffusion layers 4 and 3 formed on a semiconductor substrate 1 with an interlayer insulating film 5 in between. After forming the ports 6a and 6b, a polycrystalline silicon film 7 is formed on the entire surface of the substrate 1. Then phosphor ions are implanted into the ports 6a and 6b by using the film 5 as a mask. After implanting the ions, the film 7 in the port 6a on the layer 4 is removed and boron ions are selectively implanted into the bottom of the port 6a on the layer 4 at a concentration higher than that of the phosphor ions. Then, after depositing a metallic film 12 for wiring on the substrate 1, a desired wiring pattern is formed by selectively etching the film 12. Therefore, the N- and P-type diffusion layers 4 and 3 can be stably connected to the metallic film 12 for wiring and the mass productivity of this semiconductor device can be improved.

Inventor: TAKAGI MICHIAKI
IPC: H03H3/02
Filed: 1978-06-16
Abstract: PURPOSE:To enhance greatly the Q-value of the oscillator by improving the mass balance for both arms of the oscillator. CONSTITUTION:The process machine control signal production part generates the positive voltage to increment of the Q-value and the negative voltage signal to decrement of the Q-value each. The process machine control circuit part including the signal production part receives the start for the control process and the Q-value increment/decrement signal of the controlled crystal oscillator and then generates the selection signal for the frequency adjustment arm of the oscillator plus the control process stop signal based on the decision for the maximum Q-value. Furthermore, the process machine control mechanism receives the control signal from the control circuit part to perform the open/close control of the shutter for the evaporation and the position control for the target at the oscillator arm part of the laser beam for the laser processing respectively. Thus, the arm balance can be given automatically for the tuning fork type oscillator.

The harmful heavy metals such as Cd are selectively chelated and dissolved in the aq. phase. Accordingly, dry excess sludge contg. no harmful heavy metal is obtd., and it can be used as fertilizer and feed.

Title: Constant resistance circuit with current limit function
Inventor: TERASAKI YUTAKA
IPC: H04M19/00
Filed: 1988-03-28
Abstract: PURPOSE:To form a constant resistance circuit having various output voltage versus current characteristics through the change in a resistance value only by providing two bipolar transistors(TR), connecting the collector of a 1st TR via a reverse voltage preventing rectifier to a 1st input/output terminal and connecting the base and emitter to a 2nd TR directly. CONSTITUTION:A voltage between input/output terminals 1, 2, that is, an output voltage rises gradually from zero, then a current determined by the combined resistance of resistors 8, 9 flows as a collector current of the TR 4. In this case, an output current flowing to a loop forming circuit 13 increases in proportion to the output voltage and the output voltage versus current characteristic shows a constant resistance characteristic. Moreover, the output voltage rises further, the collector current of the TR 4 is increased and the voltage across the control current setting resistor 8 reaches the base-emitter voltage of the TR 5, then the TR 5 is activated. Then a constant current flows to the base of the TR 4, and even if the output voltage rises further, the collector current of the TR 4 becomes constant.

Title: Solid state image sensor
Inventor: NAGAI KAZUSHI
IPC: C25D7/00
Filed: 1990-03-23
Abstract: PURPOSE:To prevent plating from being peeled during assembling by nongloss or semigloss plating a lead frame, and then allowing the plated part to thermally reflow, thereby flattening the plated surface. CONSTITUTION:A CERDIP 20 is composed by adhering a lead frame 3 made of metal such as 42 alloy between a window frame 1 made of ceramics and a base 2 by low melting point glass 4. After the frame 3 is nongloss or semigloss sheath-plated 10, the plated part 10 is allowed to thermally reflow before assembling steps are started, thereby flattening the surface of the plated part 10. A solid state image sensor is assembled by using the CERDIP 20. In such a case, even if a jig is brought into contact with the surface of the part 10 during assembling of the sensor, a plating material is scarcely peeled. Thus, the quantity of the material adhered on an image sensing chip can be reduced, and the yield of the sensor can be improved.

Title: Method and apparatus for penetration of pile
Inventor: KITAMURA MORIO
IPC: E02D7/20
Filed: 1985-04-09
Abstract: PURPOSE:To penetrate piles with good efficiency by a method in which excavated soil to be produced in penetrating a pile into the ground is moved into a pit drilled along an existing pile by rotation of vanes without discharging it to the ground's surface, the soil is consolidated by a casing pipe, and the pile is penetrated by pressure. CONSTITUTION:When an excavating head 14 provided at the lowest end of a rotary shaft 10 is driven forward while crushing hard ground, vanes 13 are operated to diffuse crushed ground to sides, and thereby the penetrating resistance of a pile is reduced. When a pile-penetrating head 6 is raised and an auxiliary excavator 7 is pulled up, a pit B is formed near the pile P1. While the vanes 13 are turned, the head 6 goes down, sand and gravels are directed into the pit B, and the pit B is degradated and buried. The ground around the head of the pile to be penetrated is greatly loosened, the penetrating resistance of the pile is greatly reduced, and the pit near the adjacent existing piles is buried. The needs for operations to bury the pits can thus be eliminated and sufficient bearing capacity of the pile can be secured.
