Title: High-frequency oscillator
Inventor: KUDO TETSUO
IPC: H03L1/04
Filed: 1988-06-22
Abstract: PURPOSE:To obtain highly stable and highly pure high-frequency signals by providing an A/D converter, memory circuit, D/A converter, and voltage- controlled crystal oscillator and directly oscillating high-frequency signals. CONSTITUTION:The output frequency of a voltage-controlled oscillator 14 is divided by the 2nd frequency-divider 15 and supplied to a phase comparator as a frequency signal to be compared. The comparator 12 compares the frequency signal to be compared with a reference frequency signal in phase and outputs a phase difference signal in accordance with the phase difference between both signals. The phase difference signal is supplied to a low-pass filter 13 where the phase difference signal is integrated time sequentially and converted into a DC signal to a frequency control signal. The frequency control signal is supplied to the voltage-controlled oscillator 14. Thus the oscillator 14 is controlled by a voltage-controlled crystal oscillator 10. Therefore, the output frequencies of the VHF and UHF bands of the oscillator 14 can be obtained by the frequency stability of the crystal oscillator 10.

Title: Sheet-like heat benerating body
Inventor: MORI KIYOTAKA
IPC: A47J27/21
Filed: 1993-06-28
Abstract: PURPOSE:To improve workability, assembling asines, and safety by forming a heat generating body by etching, pressing, etc., to metal foil, and providing insulation materials provided with a through-hole for exposing the heat generating body, and a heat diffusion plate made of aluminum. CONSTITUTION:A heat generating body part 4 is made on a lower surface of a heat transmitting plate 1 through a heat conductive heat transmitting plate 3 of a flat plate. The part 4 is formed by inserting a foil-type heat generating body 7 between layers of insulation materials 5, 6. Liquid inside a container 2 is heated by energization to the foil-type generating body 7 to generate heat. The heat generating body 7 can be processed of a single plate material by etching, pressing, etc., so the number of partitems can be reeduced. In addition, because the heat generating body part 4 is handled as a single unit, workability and assembling easiness can be improved. A distance between lines can be kept constant, so breakage by contact of the lines with each other can be prevented to improve durability. Even in the case where a tmeperature controller of the heat generating body fails to cause continuous baking energization, a heat diffusion plate 11 is melted to flow into a through-hole 6a for exposing the foil-type heat generating body 4 to shortcircuit and break the heat generating body 7 to stop energization, thereby safety is improved.
