Title: Cooking utensil
Inventor: ISHIKAWA HARUO
IPC: H05B6/12
Filed: 1987-11-30
Abstract: PURPOSE:To attain the uniform and economical heat reservation by forming the bottom section of a protective frame with a nonmetallic material, forming the side section with a metallic material, arranging an induction coil on the bottom section, and arranging a resistance heater on the side section. CONSTITUTION:A protective frame bottom section 3 arranged with an induction coil 11 is formed with thermoplastic plastic, the induction heating of a pot 2 is smoothly performed. Since a heater A14 providing Joule heating is contact- fitted to a protective frame side section 4 made of aluminum-plated steel plate, the heating of the heater A14 is effectively distributed by the high heat conductivity of the side section 4 and an air layer between the pot 2 and the side section 4, the side face of the pot 2 is nearly uniformly heated, and the temperature irregularity at the time of heat reservation is prevented. The heater A14 serves as a main heat source to heat the pot 2 at the whole side section 4, thus the low efficiency of the induction heating by the coil 11 at the time of the low output is absorbed, or the induction heating by the coil 11 is not necessarily required, and the power consumption can be reduced. Heat reservation can be uniformly and economically attained.

IPC: H03M1/08
Filed: 1993-12-03
Abstract: PURPOSE: To minimize skew inducing distortion by devising it that a leading edge and a trailing edge of a signal received by a converter cell cross simultaneously a switching threshold level. CONSTITUTION: Variable delay registers(VDR) 12, 26 act like data latches, and data received by them are transferred to an output in the case that a conversion clock signal from a conversion clock device 15 transits to a low level. Output data from the VDRs 12, 26 are latched stable independently of a fluctuated input signal till a succeeding active clock edge comes. Any delay in a leading transition or a trailing transition in outputs of the VDRs is controlled by a control voltage signal generated from an error signal circuit 22. The control voltage signal is an error signal proportional to skew inducing distortion and used to minimize the skew inducing distortion.

Title: Coining device
Inventor: FUJIWARA NORIYUKI
IPC: B21D22/02
Filed: 1988-12-01
Abstract: PURPOSE:To improve the uniformity in the thickness of a work and to obtain good flatness by forming a die so as to have a projecting part in the part in contact with the work. CONSTITUTION:The surfaces of a punch 1 and the die 2 which come into contact with the work 3 are made into the projecting shape. The punch 1 begins to come into contact with the work 3 from the central part thereof when the punch descends. The peripheral part of the work comes into contact with the punch 1 and the die 2 in the lesser parts. The effect of suppressing the deforma tion of the central part to the periphery is, therefore, decreased and a plastic deformation is induced in the central part. Since the internal stress is increased by the deformation of the central part, the punch 1 and the die 2 induce the elastic deformation as well and the projecting parts are deformed nearly to a flat shape. The work 3 and the punch 1 and the die come into contact gradu ally with each other as the punch 1 descends. The working is thus applied to the work. The degrees of the plastic deformation in the central part and the peripheral part are made nearly uniform in this way and the surfaces of the punch 1 and the die 2 attain nearly the flat state as well.
