Title: Screw press with female screw fixed in slider
Inventor: ISHIKAWA TOSHIO
IPC: B28B3/02
Filed: 1980-02-21
Abstract: PURPOSE: To obtain high quality formed goods by freely adjusting pressurized force and making an ascending time of a slider approximately the same as a  descending time, wherein a female screw is fixed in a slider and a slider is moved  upward and downward by the rotation of a screw shaft.  
     CONSTITUTION: When a variable speed motor 1 rotates, a flywheel 3 rotates through V belts 2. A female screw 16 fixed in a slider 7 makes the slider 7 descend along a column 8 by the rotation of a screw shaft 4. An upper die 11 descends together with the slider 7, fits with a lower die 12, and forms raw material in the lower die 12 by a pressurized force generated by the screw shaft 4. A limit switch LS3 allows the variable speed motor 1 to rotate reversely as soon as the upper die 11 fits with the lower die 12 and gets pressured. After forming by pressure, the screw shaft reversely rotates and at the same time the slider 7 united in one body with the female screw 16 begins to ascend, while an end part of the screw shaft 4 is lubricated by lubricating oil 10 in an upper die fixing plate 9.

Title: Signal level display circuit
Inventor: TAKAHASHI KIYOSHI
IPC: H04N5/445
Filed: 1990-01-30
Abstract: PURPOSE:To adjust the level of a signal without using a measuring device by setting an output from a circuit means as a control signal and alternately switching, selecting and outputting respective outputs from 1st and 2nd comparators. CONSTITUTION:An operational amplifier A3 constitutes the 1st comparator which compares the level of a peak detection voltage Vi and a vertical saw tooth voltage Vs and an operational amplifier A4 constitutes the 2nd comparator which compares the level of a reference voltage VR by a constant-voltage source and the vertical saw tooth voltage Vs. The inversion input terminal of an operational amplifier A5 is connected to a ground potential point and a horizontal saw tooth voltage Hs from an input terminal IN3 is conducted to the non- inversion input terminal of the amplifier A5. Therefore, the outputs from the operational amplifiers A3 and A4 obtained by switching and selecting output from switches SW1 and SW2 are synthesized to a signal (d) having one path to be displayed on a picture tube CRT. Thus, the level of the image signal is adjusted with a sense of viewing a level meter displayed on a screen without using the measuring device.

IPC: G01G3/00
Filed: 1986-02-03
Abstract: PURPOSE:To achieve accurate measurement of weight free from the effect of temperature or the like, by arranging a pressure-sensitive sensor adapted to convert a pressure force into an electrical signal and a detection circuit for detecting the weight from the electrical signal, the pressure-sensitive sensor being coated with a water repelling material. CONSTITUTION:The construction of a pressure-sensitive sensor 1 is illustrated at a weight detector section with limited displacement. This pressure-sensitive sensor 1 is made up of two flat plates 2 of insulator being elastic each with an electrode printed. The plates 2 are stuck together through a spacer 4 and made of ceramics or the like. With such an arrangement, the pressure-sensitive sensor 1 is so small and limited in the displacement to shut down an electric clearance easily from outside. The outside of pressure-sensitive sensor 1 is coated with a sensor coat 5 comprising a water repelling material, thereby eliminating effect of leakage current due to moisture, dew formation, dust and the like. The sensor coat 5 is composed of 4-ethylene fluoride or the like.

Title: Heating and cooling furnace
Inventor: OKADA MASAKI
IPC: F27D1/12
Filed: 1990-01-31
Abstract: PURPOSE:To provide a heating and cooling furnace without precluding the increase and the reduction of a temperature in the furnace by a method where-in the inner wall of a heating and cooling chamber is coated with a surface heat transmitting layer having small heat conductivity and heat capacity. CONSTITUTION:A heating and cooling furnace 100 is covered by a ceiling plate layer 4 consisting of the thin sheet of high-strength ceramics such as silicon nitride and the like while the ceiling plate layer 4 is supported by a supporting unit 21, consisting of a ceramics thin sheet having a small heat conductivity such as zirconia and the like, with respect to the inner wall of the furnace. Accordingly, a heat conductivity from the surface of the inner wall of the heating and cooling chamber to the inner wall of the furnace and the heat capacity of the surface of said inner wall become very small. In such a heating and cooling furnace 100, even if the inside of the heating and cooling furnace 100 is heated to a high temperature condition by a heating device 106, for example, heat conduction from the ceiling plate layer 4 to a casing 101 can be precluded since the supporting unit 21, supporting the ceiling plate layer 4, is provided with a low heat conductivity and the flow passage of heat is small. On the other hand, when the heating device is stopped from a heating condition and a cooling device 104 is operated, the temperature of operating fluid in the heating and cooling furnace 100 is reduced immediately.

Filed: 1984-02-10
Abstract: PURPOSE:To attain a instantaneous switch to a spare circuit corresponding part by transmitting an action mode setting inducement response from a packet exchange every fixed interval and giving initialization to a data link set between the packet exchange and a terminal circuit. CONSTITUTION:A switching action to a spare circuit corresponding part 2b is carried out as follows. At the outset, a CPU1 sends a parameter designating signal 10 to the part 2b to attain a presently desired action. Then the CPU1 transmits an action mode setting inducement DM command 5 to the part 2b so as to transmit continuously the DM responses 6 in a connection mode to a circuit 3. No response 6 is transmitted since the circuit 3 is not connected physically to the part 2b before the connection is switched to the part 2b. Then the CPU1 delivers a switching preparatory end report 11 which shows that the preparatory is through with switching to the part 2b. Then a working circuit corresponding part 2a is switched to the part 2b by a switching signal 12.

Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To surely open circuit when the element is broken through by provid ing a groove on the surface of the outer periphery of the mold resin on the line horizontally extended from an electrode plane and a lead terminal connecting plane. SOLUTION: When an abnormal high voltage, not tolerated by a varistor element 1 is applied, the varistor element 1 is broken through. In such case, the temperature of the broken varistor element 1 becomes high, a part of the composition evaporates, and high temperature and high voltage gas is generated. The pressure of the gas operates to break mold resin 5, generates a crack along a groove 7 on the surface of the mold resin 5 on the line horizontally extended from the connecting plane of an electrode plane 2 and a lead terminal 3a, and breaks the mold resin. With the lead terminal 3a, the mold resin 5 on the top plane of the varistor element 1 removes just like a cover opens by the gas pressure, and an electrically open circuit condition is provided. Thus, the element is surely open circuited at the time of failure.

Filed: 1985-02-07
Abstract: PURPOSE:To obtain a piezoelectric diaphragm with a low frequency but high sound pressure by adhering alkoxide chemical compound to a metal thin plate, applying hydrolysis and heat processing and polarizing after electrodes are formed. CONSTITUTION:The alkoxide compound is adhered to the titanium thin plate subject to ultrasonic rinsing. In applying heating and hydrolysis, a transparent amorphous film having (Pb0.93La0.07)Zr0.65Ti0.35O3 as major component is formed on the titanium thin plate. After the plate is subject to remaining heat at 80-150 deg.C in oxygen atmosphere, the temperature rises gradually at a rate of 50-250 deg.C/hr and heat processing is applied for 2hr at 500-900 deg.C. In cooling the plate slowly under oxygen atmosphere, the amorphous film formed on the titanium thin plate is crystallized and becomes opaque.

An epoxy-zine containing epoxy resin, a hardening agent, and zinc powder in a sufficient amount to make the zinc powder content in the dried coating 50wt.% or more is used as the primary rust preventive coating material. Preferably, an epoxy resin type coating material consisting mainly of epoxy resin, a hardening agent, and a hydrocarbon resin is formed on the primary rust preventive coating film.  Consequently, excellent rust-proofness is retained even for a steel part to be submerged and the number of under coating treatment processes can be lessened.
