Title: Production of arylozxyallene compound
Inventor: AOKI HIROSHI
IPC: C07C41/01
Filed: 1988-03-15
Abstract: PURPOSE:To obtain a compound useful as a polymerizable monomer by reduced processes, by processing propargyl alcohol into a propargyl aryl ether and then allenylating. CONSTITUTION:Propargyl alcohol is reacted with a phenol shown by the formula R-OX (R is aromatic hydrocarbon residue; X is H or alkali metal) in the presence of a dehydrating agent in a solvent such as THF at room temperature -120 deg.C to give a propargyl aryl ether shown by the formula R-O-CH2-C=CH. Triphenylphosphine-carbon tetrachloride, dicyclohexylcarbodiimide-cupric chloride, etc., may be used as the dehydrating agent. Then the propargyl aryl ether is isomerized in the presence of a base (e.g., potassium alcoholate of t-butyl alcohol) to give an aryloxyallene compound shown by the formula R-O-CH=C= CH2.

Title: Magnetic recorder
Inventor: HORIUCHI KAZUHIRO
IPC: G11B19/28
Filed: 1986-03-18
Abstract: PURPOSE:To start a motor through software and to stabilize the subsequent rotation of the motor by adjusting electric power supplied to the motor on the basis of the output of a rotating speed sensor. CONSTITUTION:The rotating speed sensor 102 of a controller 100 consists of an LED 120 and a phototransistor 122 and detects the state of an encoder based upon the rotation of an optical medium disk to output a rotating speed signal K. The signal K is waveform-shaped 130 and its waveform is ANDed with the output waveform of a specific start time setting part 108 to control a motor driving part 132. The driving part 132 increases the current supplied to the motor 81 with time until a control signal P rises to 'H' and is reset. In this case, the outputs of an artificial rotating speed signal generation part 106 and a timer 140 are ORed and the OR output is used to decrease the starting current to the motor 81, thereby supplying the steady current to the motor 81 after the start.

Title: Cartridge cell
Inventor: SHINODA KENICHI
IPC: H01M2/08
Filed: 1987-03-18
Abstract: PURPOSE:To eliminate the occurrence of a short-circuit phenomenon between an outer can and a terminal board entirely from the structural viewpoint and, what is more, dispense with a beading part as well as aim at improvement in the appearance of an outer package, by forming a ring flange part, engaging an opening edge of the outer can, solidly in the top of a rising part of a gasket. CONSTITUTION:In case of the cartridge cell, setting up a terminal board 14 laminately at the inside of an opening surface of an outer can 10 via a sealing gasket 12, bending an opening edge of the outer can 10 inward together with a rising part 12a of an peripheral edge of the gasket 12, rolling it in the peripheral side of the terminal board 14, and sealing an interspace between the outer can 10 and the terminal board 14 into an insulated state, a ring flange part 12b to be engaged with the opening edge of the outer can 10 is solidly formed in the top of the rising part 12a of the gasket 12. At time of bending, the opening edge of the outer can 10 is bent in a state of being engaged with the flange part 12, and downward pressurizing force against the gasket 12 is offset by the frange part 12b, whereby it is prevented from shifting into the lower side. In addition, there is unnecessary to form a beading part in the outer can, thus good appearance is securable.

Title: Manufacture of die of high strength and high toughness
Inventor: FURUTA AKIHITO
IPC: B21J13/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a die high in strength and toughness, and a die long in service life of various shapes and dimensions by executing the plastic working only on a surface of the die, achieving the tempering thereafter, and improving the characteristic of only the surface of the die through the ausforming in a specified range of the product temperature during the hardening-cooling after machining the die. SOLUTION: A tool steel such as carbon tool steel, alloy tool steel, high speed tool steel, and plastic die steel is once heated above the Ac1 transformation point, then, the temperature is dropped, the shot peening is achieved only on the surface between the martensitic transformation point (Ms point) and 800 deg.C, and then, the cooling is achieved, and the tempering is achieved at least once. By achieving the plastic working only on the surface in the middle of the hardening, the strength, toughness, fatigue strength, softening resistance and heat checking property of the stock surface can be improved. Because this method is applicable to dies of various shapes and dimensions, the die inexpensive and long in service life can be provided.

IPC: G06F15/78
Filed: 1986-03-20
Abstract: PURPOSE:To produce a program having high efficiency by inhibiting the count-up action of a vector timer for a period during which a vector unit is not executing the vector whose processing is requested from a scalar unit. CONSTITUTION:A vector unit VU-1 receives a vector instruction requested from a scalar unit SU 120 and executes and controls it by a vector executing unit VEU (not shown here) at an instruction control part 131. At the same time, a vector timer VT 132 counts the time during which the execution of the vector instruction is started and completed. For this purpose, a timer control signal TC is applied to the timer VT 132. The timer VT 132 counts up the clock signals CLOCK for counting of time. Then the timer VT 132 is inhibited to count up the signals CLOCK for the periods excepting the time needed for execution of the vector instruction by the signal TC received from the part 131.
