Title: Template for manufacturing metal plate-reinforced cement-based board and manufacture thereof
Inventor: TAKAMOTO HIROMITSU
IPC: B32B3/24
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To obtain a template, the dimensional change of which is made as small as possible and in which a warpage is prevented from developing, by a method wherein the template is made of a metal plate-reinforced molded body having a top and a lower fiber reinforced resin layers and an intermediate layer made of a perforated metal; plate lying integrally between the fiber rein forced resin layers. SOLUTION: A liquid resin system (including an epoxy resin and a hardener) is cast in a mold by the order that the uneven pattern part 1 of the mold is buried and then three reinforcing fibrous sheets (glass fiber chopped strand mat) are spread on the cast resin system so as to pile up one another under the state that the liquid resin system is fed during their piling-up in order to form a lower fibrous reinforced resin layer 2. Then, one perforated metal plate 3 (stainless steel punching plate) is put upon the lower fibrous reinforced resin layer 2. After that, four reinforcing resin sheets are spread on the perforated metal plate and impregnated with the liquid resin system so as to form an upper fibrous reinforcing resin layer 2. By curing the resin under heat and pressure, the molding of a template is completed.  Since the fibrous reinforced layers 2 connect with each other through the opening parts of the perforated metal plate 3, the separation of the layers is prevented from occurring. Further, since the perforated metal plate 3 is not offset and exists at the middle of the thickness of a board, no warpage develops in the board.

Filed: 1986-08-20
Abstract: PURPOSE:To prevent an electric shock due to a discharge wire exposed when the discharge wire is cut, by installing the discharge wire between spring bodies under tension and contacting a high voltage applying part with the spring bodies only when the discharge wire is installed under tension. CONSTITUTION:When a pawl 12 is engaged with the engaging part 9 of a discharge wire 6 and the discharge wire 6 is installed under tension by the energizing force of a spring body 11, an ion is generated by the application of high voltage. When the discharge ire 6 is cut at the intermediate part thereof in a tensioned state, the spring body 11 returns to the original position by the recovery force thereof but, since the spring body 11 is spaced apart from a high voltage applying part 14 at almost the same time when the spring body begins to restore, no high voltage is applied to the discharge wire 6. Since the engaging part 9 of the discharge wire 6 brought to a non-charging part is easily detached from the pawl 12 along the warpage at the leading end part thereof because the open end of the pawl 12 turns downwardly on the way of the restoration of the spring body 11 and, even when the discharge wire is exposed to the outside, safety is achieved.

Abstract: PURPOSE:To attain the notice of a power voltage drop as a change in a melody frequency, or a speed change or a simultaneous change of the frequency and speed by receiving a decode output and the output of a voltage detection section and controlling a melody generation section. CONSTITUTION:When the voltage of a power supply 212 of a voltage detection section 109 is lower than a preset voltage generated from a reference voltage generating circuit 211, the output SLVS of a comparator 213 goes to H. Since its own call number is not yet detected, an output SDEC from a decoder 103 goes to L, resulting that the output SPDC of an AND circuit 222 of a melody control section 105 goes to H. The H level of the output SPDC is fed to a programmable frequency divider 223 simultaneously. The frequency divider 223 frequency-divides the clock from a reference clock section 110 with a 1st predetermined frequency division ratio to generate an output SCLK when a control signal input is at an L level and frequency-divides the clock with a 2nd frequency division different from the 1st predetermined frequency division ratio to generate an output SCLK when the control signal input is at an H level.

Abstract: PURPOSE:To perform reliable production of a work with a high surface finishing precision all the time by a method wherein each time a reduction amount of an actual radius due to a work to polish a work exceeds a given value, an outer peripheral grinding surface is corrected. CONSTITUTION:Along with measurement of size available after a grinding work of a work 3 by means of s size measuring device 23, the position of the machining surface of the work 3 is determined and simultaneously a feed amount of a grinding stone 2 when a grinding work is effected is determined.

Title: Thin type air cylinder with fall prevention
Inventor: HIGUCHI YASUO
IPC: F15B15/14
Filed: 1995-06-27
Abstract: PURPOSE: To provide a thin type air cylinder at a low cost which is small and can be prevented from falling, by building a brake rod into a cylinder by being eccentrically shifted from the shaft of the cylinder and being in parallel thereto, and rotatively attaching to a piston, a brake member which is fitted to the brake rod by making a position eccentrically shifted from the brake rod to serve as a fulcrum. CONSTITUTION: When air is supplied from a port A, a brake member 7 gets around a spring and is pressed to a piston 5 so as to be in parallel to a brake rod 4 so that a brake is released. When the air is supplied from a port B and discharged from the port A, the brake member 7 is inclined by the spring, however, its force is little and its action is related with a one-way clutch. When the air is discharged from the port B, an angular moment is applied to the brake member 7 by making a fulcrum screw 11 to serve as a fulcrum by the spring. When the gravity of a movable part is applied to the piston rod 6 under this condition, a load causes the angular moment to the brake member 7 through the fulcrum screw 11, and causes frictional force between the brake member 7 and the brake rod 4. Hereby, the movable part can be prevented from falling.

Abstract: PURPOSE:To prevent the infuence of malfunction due to electromagnetic wave disturbance from extending by paying attention to the temporarity of the electromagnetic wave disturbance and stopping or reducing the function of electric equipment for the period of the disturbance. CONSTITUTION:An antiskid control circuit 11 uses a CPU, so a program runa way is considered. For the purpose, a runaway detecting circuit is provided and a relay driving circuit 12B is driven with an inhibition output INH' generat ed by the runaway detection of the detecting circuit. In this case, a normally-on relay 12A takes a measure to counter the electromagnetic wave disturbance only by inputting the inhibition output INH of an electromagnetic wave distur bance detecting circuit 13 to the circuit 12B. Namely, when the relay 12A is turned off, a solenoid 21 can not be powered on, so brake hydraulic pressure can not be reduced by a control circuit 11 forcibly. Namely, the effect of the brake enters a normal state wherein an antiskid controller 1 is not added, so braking effect corresponding to the operation of a driver is expected.
