Title: Saws
Inventor: MIYAWAKI UICHI
IPC: B27B21/00
Filed: 1981-06-05
Granted: 1984-08-09
Abstract: The blade for a cross-cutting saw includes alternately splayed cutting teeth each tapered to a sharp cutting edge on its outer surface, with an acute taper angle (alpha). A certain number of cutting teeth, at various points along the length of the blade, form auxiliary cutting teeth which are splayed at an angle that is less than that of the main cutting teeth. The main and auxiliary cutting teeth are splayed at angles X and Y, res- pectively, to the central plane of the blade and form angles (delta) and (beta) respec- tively to the horizontal. The angles are such that (X+alpha+delta) and (Y+alpha +beta) are both equal 90 deg.

Title: Read only semiconductor memory device
Inventor: KITAJAWA SHYOJI
IPC: G11C17/12
Filed: 1985-11-18
Granted: 1990-11-05
Abstract: The memory includes a matrix array of cells each formed of a MOS transistor (2). The memory is controlled by a word line decoder (7) and a data line decoder (9) which operates via a multiplexer (8). The source of each MOS transistor (2) is coupled to a common line (5) itself subjected to a voltage intermediate the supply voltage and earth. When a reading operation is made, the word line decoder (7) drives the 'on' transistor alone, since the common line voltage is sufficently close to the word line voltage that 'off' transistors do not form inversion layers which would result in a large capacitive loading on the line.

Title: Method of making shaped ceramic composites with the use of a barrier
Inventor: NEWKIRK MARC S
IPC: C04B35/65
Filed: 1987-05-08
Granted: 1995-04-25
Abstract: In the present invention, there is provided a method for producing a self-supporting ceramic body by the oxidation of a parent metal to form a polycrystalline ceramic material consisting essentially of the oxidation reaction product of said parent metal with an oxidant, including a vapor-phase oxidant, and optionally one or more metallic constituents. The method comprises the steps of providing at least a portion of said parent metal with a barrier means at least partially spaced from said parent metal for establishing at least one surface of the ceramic body, and heating said parent metal to a temperature above its melting point but below the melting point of the oxidation reaction product to form a body of molten metal. At that temperature, the molten metal is reacted with the oxidant, thus forming the oxidation reaction product. At least a portion of the oxidation reaction product is maintained in contact with and between the molten metal and oxidant to transport the molten metal through the oxidation reaction product toward the barrier means and into contact with the oxidant so that the oxidation reaction product continues to form at the interface between the oxidant and previously formed oxidation reaction product optionally leaving metal dispersed through the polycrystalline material. The reaction is continued to the barrier means to produce a ceramic body having the surface established by the barrier means. A composite is formed by superimposing a barrier onto a filler material, such as a preform, and infiltrating the filler with the polycrystalline ceramic matrix grown to the barrier means.

Abstract: When fuel gas is ignited by an ignition burner and a flame is transferred to a pilot burner, a burner and the ignition is detected, a solenoid valve (11) is kept at open condition. And when the valve (11) is kept at open condition and the ignition is not detected. After an open time of 0.7 sec. elapsed, the valve (11) is closed. If a closed time of 0.5 sec. elapsed and a trial timer circuit (32) is not stopped, the valve (11) is opened again. As the operation time of the circuit (32) is, for instance, for 3.6 sec., the valve (11) is opened three times and three chances for the ignition are provided by one feed water operation. As the valve (11) is closed for 0.5 sec., the fuel gas is dispersed and the safe ignition can be carried out.
