IPC: F16B5/02
Filed: 1994-04-11
Abstract: PURPOSE:To obtain an attaching method for a bent plate spring to be smoothly operated and to be easily attached by pressing a base part through a process of inserting the ends of a wire member into holes or grooves of the base part from below to above after loosely supporting an approximately center part of a bent part of the plate spring by means of a screw, and also by pressing a tip bent part of the wire member by means of a screw and then attaching it to a plate. CONSTITUTION:A bent plate spring 7 is smoothly bent from a base part 7a, and a supporting part 7b projects, so as to support a member 4 to be supported. Next, a hole 7c is provided in the approximately center part of a bent part between the base part 7a and the supporting part 7b of the plate spring 7. The plate spring 7 is pinched by an expanded part of a cylindrical body 13 and a flush head of a screw 9. Next, the end of an approximately V shaped wire member 22 is inserted into holes 7c or grooves of the base part 7a of the plate spring 7 from below to above, so as to press the base part 7a, and to press the tip bent part of the wire member 22 together with the cylindrical body 13 by the screw 9, thereby it is fixed on the plate 3. As a result, a cost can be reduced since the wire member is used for an attaching method for the plate spring 7.

IPC: F16K31/143
Filed: 1987-05-06
Abstract: PURPOSE:To improve the safety and quick response by arranging a manual operating section for rotary driving a valve rod through a plurality of gears below an automatic operating section comprising a fluid cylinder. CONSTITUTION:An automatic operating section 54 pushes up upper and lower pistons 80, 79 through pressure of air fed from an air chamber 83 during open- valve operation. Consequently, a valve rod comprising a threaded rod 57 lifts up a valve body thus opening a valve. During close-valve operation, the upper piston 80 is pushed down by the pressure of air fed into an air chamber 90. When a handle 75 in a manual operating section 53 provided below the automatic operating section 54 is rotated, a slide pipe 61 is moved up and down through a drive spiral gear and a driven spiral gear 69.

Title: Air convective construction inside wall body in house built by steel framed panel method
Inventor: YAMADA YASUYOSHI
IPC: E04B2/56
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To permit sufficient air convection between building wall bodies in a building method forming wall surface by using building wall bodies. SOLUTION: H-shape steel 10 is installed in such a manner that two first steel plate 10a constituting the H-shape steel straddles two neighboring building walls 1a, 1b. By doing this, a space 15 is formed between the H-shape steel 10 and each of building wall bodies 1a, 1b. Air passes from the internal space 14a of the building wall body 1a to the space 15 and goes out from the internal space 14b of the building wall bodies 1b. In this way, an air flow route is formed so that air or moisture does not stay in a building wall body, thereby preventing the corrosion due to moisture for the building wall body.

Filed: 1984-05-29
Abstract: PURPOSE:To join smoothly and quickly the ends of a preceding material and succeeding material and to improve efficiency and quality by subjecting simultaneously said ends to connection by press welding and to rolling. CONSTITUTION:The slab extracted from a heating furnace is rolled down by a roughing mill and thereafter the nose of the slab is raised by a nose raising roll E.

The preceding material is fed to a finishing mill and is engaged wth the top of the succeeding material at the speed controlled by pinch rolls C so that the ends of the two materials are superposed in the position just near a crank mill F so as to have an allowance for a lap. The feed speeds of both materials are thereafter synchronized by controlling the pinch rolls C until the materials arrive at the draft position of the mill F; at the same time, the materials are transferred in the chamber J and are press-welded during traveling in the chamber by the mill F.

Title: Semiconductor device and manufacture therefor
Inventor: YOSHII SHINTAROU
IPC: H01L21/02
Filed: 1980-08-11
Abstract: PURPOSE:To hold a shallow junction, by a method wherein an internal layer for preventing diffusion of an element region is provided by implanting impurity ions forming an electrical inactive compound against a semiconductor substrate. CONSTITUTION:A layer 2 is formed by implanting electrical inactive impurity ions such as O, N, C and the like to an Si substrate 1 at the depth just under a desired shallow junction and with high concentration. The diffusion coefficient in Si of these inactive atoms is very low and the ions are not distributed again by a thermal treatment process to compose a stable internal layer which acts as a diffusion-proof wall to the substrate inside against the active impurity atoms such as B, P, As and the like. Therefore, the formation of a shallow junction becomes possible. A source and a drain 3, 4 are provided as usual and a device is formed by high-temperature thermal treatment or by heating by laser beams 5. In this composition, a shallow  junction is formed and a high-speed device is made possible. Furthermore, punch  through can be prevented and further element isolation can be facilitated.

Title: Light spectrum measuring device
Inventor: IWASAKI TAKASHI
IPC: G01J3/02
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To improve reliability of measuremnt of spectrum by providing a means for impressing reverse bias voltage on a photodetector for avoiding saturation of the photodetector. SOLUTION: Only the specific wavelength component 2A of out-going light from a light source 1 is received with a photodetector 3, and after photoelectrically transferring and amplifying it, it is converted into a digital signal. The maximum output current in the non-saturated state of the photodetector 3 is stored in a control part 6. The output current of the photodetector 3 is obtained from the output value of an A/D converter 5 and the amplification factor of an amplifier 4, and when it is over the maximum output current stored in the control part 6, the control part 6 commands a voltage impressing means 8 to impress reverse bias voltage on the photodetector 3. When the reverse bias voltage is impressed, the light input intensity at which the photodetector 3 begins to be saturated is enlarged.  When the output value of the A/D converter 5 is not in the appropriate range, the amplification factor of the amplifier circuit 4 is changed. When the reverse bias voltage control or change of the amplification factor is carried out, the light intensity is measured again by the A/D converter 5.
