Title: Video sound transmitter
Inventor: HAMADA FUMIO
IPC: H04N19/80
Filed: 1990-10-08
Abstract: PURPOSE:To realize satisfactory transmission of voice by controlling the bit allocation of plural voices by means of an input voice level detection circuit and a bit control circuit. CONSTITUTION:The levels of voice signals to voice input terminals S1 to Sn are detected while output levels A1 to An of a low-pass filter 23 is inputted to an input level detection circuit 1, and information is transmitted to a bit number control circuit 2. The circuit 2 controls the number of bits of the input S1 so as to be increased while utilizing the allocation bit of input S2 when there is preliminarily determined priority, for example, the priority in the voice input of the terminal S1. When the priority is not set, the bits of all channels except input S2 are added. The allocation is performed by a parallel/serial conversion circuit 25 through the control of the circuit 2. Thus, the satisfactory noise can be transferred by reducing quantization noises in a channel where the number of bits is increased.

Title: Induction-heated cooking appliance
Inventor: KAME MASAHIRO
IPC: H05B6/12
Filed: 1991-10-18
Abstract: PURPOSE:To heat a load judged as inadequate due to a small shape via the selection by a user by providing a switch turning-on/off the output signal of a load detecting device to an oscillation controller. CONSTITUTION:When a load judged as inadequate by a load detecting device 8 is to be heated, a user turns a switch 9 off. Even if the device 8 judges the load as inadequate and outputs the signal, the signal is not inputted to an oscillation controller 7 because the switch is opened, the controller 7 allows the oscillation of a switching element 6, and the element 6 excites a heating coil 4 to heat the inadequate load. The switch 9 is turned on to stop the heating of the inadequate load such as a knife or a fork, the switch 9 can be turned off via the selection by the user to heat the inadequate load having a small shape, safety is secured, and operability can be improved.

Title: Separation and analysis of trivalent chromium and hexavalent chromium
Inventor: SHIROMIZU YOSHIMI
IPC: G01N30/06
Filed: 1986-11-13
Abstract: PURPOSE:To analyze trivalent and hexavalent chromium in one process each quickly, by mixing a solution to be inspected containing trivalent and hexavalent chromium with an ethylenediaminetetraacetic acid aqueous solution to react. CONSTITUTION:A solution to be inspected containing trivalent and hexavalent chromium such as etching waste liquor discharged in a process of manufacturing a photomask or the like is mixed with an EDTA (ethylenediaminetetraacetic acid) aqueous solution to transform the trivalent chromium into Cr(EDTA)<-> by reaction. The Cr(EDTA)<-> thus obtained and CrO4<-> from natural transformation between the hexavalent chromium and water by hydration are determined by a measuring method based on difference of molecular weight, for example, a chromatography in which a small amount of an aqueous solution containing Cr(EDTA)<-> and CrO4<-> is fed to pass through a resin column to timewise determine the liquid passed therethrough, especially, an ion chromatography for determining negative univalent ions. This enables separation and analysis of trivalent and hexavalent chromium quickly in one process each.

IPC: B60S1/54
Filed: 1985-11-29
Abstract: PURPOSE:To defrost automatically a wind shield quickly and prevent it from being frosted for effecting comfortable air conditioning without using a compressor by controlling not only an amount of blow-off air from a defroster plenum but also a ratio of inside air to outside air for air conditioning. CONSTITUTION:When it is detected by a frost sensor 16 that a wind shield is frosted, an air plenum change-over damper 6 is controlled in such a way that an amount of blow-off air from a defroster plenum 1a is increased or decreased depending on the condition of frosting. And an inside/outside air change-over damper 3 is simultaneously controlled in such a way that the opening is changed over. Accordingly, a volume of air from the defroster plenum 1a is increased as the condition of frosting on the wind shield F is degraded, besides, a volume of suction air is increased to reduce the humidity of blow-off air. An electronic control circuit 13 is adapted to control the above mentioned operations automatically for reducing suction air from the outside as the wind shield is defrosted so as to eliminate a need for an actuation of an air compressor of an air conditioner without degrading the efficiency of air conditioning.
