IPC: B60H1/03
Filed: 1989-02-17
Abstract: PURPOSE: To facilitate maintenance for a heat exchanger or other component parts by providing a contact type temperature sensor for stopping a heater to prevent overheat of a temperature sensitive part on the outside of a jacket casing and in the heat transferring state to the heat exchanger. CONSTITUTION: A contact type temperature sensor 12 functioning as a temperature safety device is arranged on the outer surface of a jacket casing 7 near a closed end of a heat exchanger 5. A projection 13 is formed in an arrangement area for the contact type temperature sensor 12 of the heat exchanger 5, and a projection 14 is formed on the opposite side to form a direct contact part between the jacket casing 7 and the heat exchanger 5. Thus, the contact type temperature sensor 12 and the heat exchanger 5 are connected to each other to be thermally conductive. The sensor 12 is connected to a control device by lines 15, 16. This arrangement simplifies the constitution for heater protection.

Filed: 1987-02-20
Abstract: PURPOSE:To prevent simultaneous selection of row lines by using a NAND signal of a direct transmission signal and an inverted transmission signal of an address signal so as to control a word driver circuit thereby eliminating simultaneous high level portion in both the signals. CONSTITUTION:Noninverting transmission signals phi1, phi2 of address signals from 1st and 2nd gate circuits 1, 2 are subjected NAND processing by a NAND circuit G0, and the simultaneous high level portion of both the signals is eliminated from the control signal and fed to word driver circuits WD1, WD2 comprising the NAND circuit. The signals phi2, phi1 via delay circuits D1, D2 having the same delay time as the circuit G0 are fed respectively to the circuits WD1, WD2. Thus, the output of the circuits WD1, WD2 goes not reach simultaneous high level and the simultaneous selection of row lines X1, X2 of the word line is prevented. As a result, the increase in the power current and the distortion in the output waveform are eliminated and the access time is reduced.

Title: Molding material
Inventor: KOBA TOMOHITO
IPC: B29K105/06
Filed: 1988-02-22
Abstract: PURPOSE:To better dispersion properties at the time of injection molding, lessen snappings of fibers and increase impact strength by specifying the filling rate of a fiber-like reinforcing material and covering the surface of single fiber as a constituting unit of the fiber-reinforcing material with thermoplastic resin. CONSTITUTION:The filling rate of a fiber-like reinforcing material is made 50wt.% or more to 90wt.% or less in a molding material composed of thermoplastic resin and the fiber-like reinforcing material, and fiber-like reinforcing materials are disposed almost horizontally and continuously in the axial direction or all over the overall length of the molding material. Further, the surface of 90% or more of single fibers as the constituting unit of the fiber reinforcing material is covered with thermoplastic resin. High filling of fiber can not be carried out, if the filling rate of fiber-like reinforcing material is 50wt.% or less, while the surface of single fibers cannot be covered sufficiently with thermoplastic resin, if the filling rate is 90wt.% or more, to generate snappings of fibers at the time of injection molding. As the surface of 90% or more of single fibers is covered with resin and respective single fibers are dispersed in resin sufficiently, the void of the molding material is 10% or less, and fibers are impregnated well with resin.

Title: Scroll type laminated heat exchanger
Inventor: SAHO NORIHIDE
IPC: F28F3/08
Filed: 1981-03-20
Abstract: PURPOSE: To reduce the occurrence of deflected flows of fluids and to improve the heat transfer capacity of the titled heat exchanger by a method wherein each of spacers 7 is made to have a spiral configuration and a plurality of fluid passages communicating with one another in the spiral direction are formed in the radial direction of the spiral.  
     CONSTITUTION: The configuration of each of the spacers 7 is in the form of an involute curve. Heat transfer plates 9 each made of a metallic plate having a number of holes 8 and the spacers 7 are laid one above another in an alternative fashion and the connecting portions of the heat transfer plates 9 and the spacers 7 are bonded together by use of a bond. Further, the fluid passages 3a and 4a for the fluids A and B communicate with each other on each of the heat transfer plates 9 and the width of each of the fluid passages is constant throughout the section extending along the involute curve. The heat exchange between the fluids A and B is performed through the transfer of heat in each of the heat transfer plates 9 in the radial direction. In this case, at the passages for the same fluid are in communication with one another on each of the heat trans-plates 9, the variation of fluid pressure in the passages among the plates 9 is absorbed in the overall fluid pressure in the entire length of the fluid passage  as a whole. As a consequence, the deflection of the flow of each of the fluids in the direction  of lamination of the heat transfer plates 9 hardly takes place so that the heat transfer capacity of the heat exchanger is improved.
