Filed: 1987-12-08
Abstract: PURPOSE:To coat the surfaces of core particles with a shell material and to obtain a toner for low-temp. fixing having good fixability and offset resistance by dispersing the solid core particles into a soln. to an aq. medium set in the basic pH region of the shell material of the capsule toner and changing the pH of the liquid dispersion to the pH region where the shell material precipitates from the liquid dispersion. CONSTITUTION:The solid core particles having a prescribed grain size are dispersed into the soln. to the aq. medium set in the basic pH region of the core material of the capsule at the time of producing the capsule toner to be used for an electrophotographic method, electrostatic printing method, magnetic recording method, etc. The pH of the liquid dispersion dispersed with such solid core particles is changed until the shell material is precipitated from the liquid dispersion, by which the surfaces of the core particles are coated with the shell material. The greater part of the function of heat fixability is imparted to the core material. The use of materials having good toner characteristics such as developability and preservable property of the dry toner as the shell material is enabled. The toner for low-temp. fixing having the good fixability and excellent offset resistance is thus produced.

IPC: H01L27/108
Filed: 1986-12-26
Abstract: PURPOSE:To simplify a process, and to inhibit the area of a cell at a small value by reacting a metallic layer and an silicon substrate or polysilicon, forming an silicide compound layer and removing the metallic layer left without executing an silicification reaction. CONSTITUTION:A P-type epitaxial layer 2 is grown onto a P<++> type silicon (a crystal fase 100) substrate 1 containing boron in a high concentration. A polysilicon layer 5 containing phosphorus (P) is shaped onto the whole surface, and buried through reactive ion etch ing. A metallic (Ti) layer 9 is formed onto the whole surface, and silicide compound layers (TiSi2 layers) 10 are shaped selectively onto the silicon substrate 1 and the polysilicon layers 5. Since the space of regions 15 on a capacitor insulating film 4 is narrowed extremely as 200Angstrom  at that time, the TiSi2 layer 10 is left between these regions 15, thus automatically connecting the polysilicon layers (capacitor electrodes) 5 and adjacent N<+> diffusion layers 8. Accordingly, a process is simplified, and the area of a cell can be reduced.

Filed: 1993-11-15
Abstract: PURPOSE:To prevent a sink mark on an upper cover and a board by placing a spacer member having an attaching means for tightening the upper cover and a first board together and an attaching means for holding a second board between the first and second boards. CONSTITUTION:An upper cover 1 is temporarily fixed in an order of a control button 3, a conductive rubber switch 4, a board 5 and a spacer 7. Then a board 6 is temporarily fixed, while being fixed to a boss 7b by a screw 9. A height of the boss 7b is at or less than a distance between the boards 5, 6, while no hole is opened on the board 5 for permitting the boss 7b to pass through. When the board 6 is fixed by a screw, a boss 7c is to be brought into contact with the boards 5, 6. Thus, the control button 7 is pushed up as indicated by an arrow, and even if force for flexing is applied to the board 5, rigidity of the board 6 suppresses flexing of the board 5, thereby reducing the number of screws 8 for attaching the board 5 to the upper cover 1.

Filed: 1991-11-25
Abstract: PURPOSE: To eliminate the restriction of the number of stages by synchronizing the subsequent edges of first and second clock signals, and delaying the leading edge of the second clock signal against the leading edge of the first clock signal by time equal to the passage time of a second inverter. CONSTITUTION: The input of a first inverter I1' becomes H, the output becomes L, a transfer transistor T'1 is turned on by a clock signal F1' and it is supplied to a second inverter I2'. Time when count up output VA being the output is changed to H is slightly delayed compared to the rise of the H level of the signal F1' by delay in the inverter I2'. When the rise time of the H levels of the signals F1' and F2' is similar, the L level is supplied to the inverter I1' by a third transfer transistor T3' before output VA changes to H and the signal which becomes H is possibly set to be L again. Consequently, the signal F2' is delayed by time (t) at second inverter passage delay time by the signal F1' for removing the phenomenon.

Abstract: PURPOSE:To obtain the subject heat-treating furnace capable of uniformly heat- treating a traveling strip in respective atmospheric gases by separating a heat- treating space into preceding and succeeding zones by the intermediate sealing device, and differentiating the atmospheric gases in the respective zones from each other. CONSTITUTION:The atmospheric gas is introduced into the space between the sealing devices 6 and 7 from the upstream zone 8 through one passage hole 12 of the sealing means 6 at a high flow rate.

Title: Manufacture of metal foil clad ceramic board
Inventor: ERIGUCHI HIDENORI
IPC: H05K3/38
Filed: 1991-11-25
Abstract: PURPOSE:To reduce water absorption properties, improve electric characteristics and mechanical characteristics at the time of moisture absorption, and enhance the adhesion between a metal foil and a ceramic layer, by impregnating voids in a ceramic layer formed by flame-spraying ceramic on a metal foil with liquid state thermosetting resin, and hardening the resin by heating. CONSTITUTION:An alumina-sprayed layer is formed by flame-spraying alumina on a copper foil by plasma spraying. The alumina-sprayed layer of an alumina- sprayed copper foil is coated with liquid wherein epoxy resin is diluted with solvent, by a doctor blade method. The solvent is eliminated by heating process and, at the same time, the resin is turned into a B stage. The two resin coated alumina-sprayed copper foils are so stacked that the alumina-sprayed layers face each other, and a copper clad alumina board is formed by heating with pressure. By this method, a multilayered board wherein voids in the ceramic layer are sealed with resin can be easily formed at a low cost. Since the alumina layer exists adjacently to a circuit, heat dissipation properties are excellent, and heat resistance and surface hardness are large.
