IPC: G06F7/544
Filed: 1981-09-29
Abstract: PURPOSE:To decrease the number of steps of a microprogram greatly by specifying addresses of a constant ROM on indirect basis, and by using microinstructions for specifying arithmetic between a constant and a variable in common without reference to the contents of the constant. CONSTITUTION:Prior to the arithmetic of an expanded expression of sinX, x, s<2>, and 0 are set to resistances R1, R2, and R3 in a register group 4. Then, a constant ROM 2 uses the contents of a counter 8 as a ROM address for addressing to output a constant from an adress (k) of the ROM 2. Once a microinstruction is executed, 1 is added under the control of a microprogram storage/control part 9. Consequently, a new step is executed to perform correct arithmetic while terms are changed successively even when the same step is executed repeatedly.

Title: Heating and cooking device
Inventor: UEHASHI HIROYUKI
IPC: F24C7/08
Filed: 1991-06-26
Abstract: PURPOSE:To detect a variation of water vapor heated by a food and to enable a heating control to be carried out by a method wherein the first and second thermistors are fixed to an outer surface and an inner surface of a duct and outputs of amplifier circuits for these thermistors are compared with a predetermined voltage. CONSTITUTION:As vapor is started to generate from a food, a temperature of a thin metallic plate 12 and a temperature of the second thermistor 15 directly contacting with vapor are increased due to the fact that a heat energy in vapor is higher than a heat energy of a reference air in a closed spacing 20, resulting in that a resistance balance with the first thermistor 14 is destroyed and a rapid increasing of an output Vo is generated. Then, heat of the vapor is transmitted to the first thermistor 14 through the thin metallic plate 12 with a certain delay. At this time, vapor dew formed at the second thermistor 15 absorbs latent heat, the temperature is decreased, the resistance balance between the first and second thermistors is reversed and the output Vo is rapidly decreased. Accordingly, the output Vo is compared with a set level Ve, thereby a heating control for terminating a heating operation is enabled when the output Vo exceeds Ve.

IPC: B01D61/50
Filed: 1978-12-18
Abstract: PURPOSE:To prevent the adhesion of scale to dialyzer and membrane by keeping the concentration of salt constant by introducing a part of desalted water formed in an electric dialyzer consisting of fours cells, desalting chamber, divalent anion- cation concentration chambers, and monovalent ion concetration chamber, into the monovalent ion concentration chamber. CONSTITUTION:The original water 5 is directed to the desalting chamber (beta) built up of the usual type anion-cation exchange membranes 3 and 4 for desalination, and ca<2+> and Na<+> move to the divalent cation concentration chamber (alpha2) and SO4<2-> and Cl<-> move to the divalent anion concentration chamber (alpha1). The cation in the concentration chamber (alpha2) moves toward the cathode 2, but monovalent cation alone, such as Na<+>, etc., moves to the monovalent ion concentration chamber (gamma) through the monovalent ion selectively permeable membrane 12 and divalent cation, such as Ca<2+>, etc., stays in the concentration chamber (alpha2). Similarly, the anion in the concentration chamber (alpha1) moves toward the anode 1, but monovalent ion, such as Cl<->, etc., moves to the concentration chamber (gamma) through the monovalent ion selectively permeable membrane 11 and divalent anion, such as SO4<2->, etc., stays in the concentration chamber (alpha1).

Title: Time synchronous system
Inventor: TSUKADA KAZUO
IPC: G01S1/30
Filed: 1977-12-22
Abstract: PURPOSE:To realize the time synchronous system for the omega receiver which supplies the signals of more than two necessary transmission stations with nearly the same level at the automatic synchronous time and with the smoothed operation for the automatic synchronization and can extract and receive the strongest station at the manual synchronous time. CONSTITUTION:At the automatic synchronous time, input signal 1 is amplified (2) and then applied to AGC amplifier 3 featuring the delay AGC characteristics. The output signal is led to detector 5, and the envelope of the reception signal is detected. Then reception timing signal 8 is produced by stable clock signal input 7 and then piled on the output given from detector 5 through synchronous detector circuit 9 to carry out the non-coincidence detection. The pulse signal of the number according to the length of the non-coincidence output signal is delivered. And in case count number 10 exceeds the fixed level, the incomplete synchronization is decided to produce the alarm output. While at the manual synchronous time, the gain of amplifier 2 is increased by control input 4. At the same time, amplifier 3 is altered for its characteristics in order not to feature the delay characterisitics.

Title: Nonaqueous electrolyte battery
Inventor: HARA MITSUNORI
IPC: H01M4/62
Filed: 1986-07-02
Abstract: PURPOSE:To prevent deterioration in battery performance and to increase working efficiency in production by using silicone-acrylic copolymer as a binder of a positive electrode. CONSTITUTION:Silicone-acrylic copolymer is used as a binder of a positive electrode. Preferable mixing amount of the copolymer to the positive electrode is 0.5-3.0wt%. Since the binder contains silicone, decomposition temperature is high, and at a high temperature of 300 deg.C or more, film forming capability of the binder is not lost. Therefore, high temperature treatment of the positive electrode is made possible, moisture in the positive electrode is sufficiently removed, and deterioration in battery performance caused by residual moisture can be retarded. Even when the binder is used alone, sufficient mechanical strength is obtained in a very thin electrode. Therefore, since a thickening agent such as polyvinyl alcohol is not necessary, heat treatment process for removing the thickening agent is eliminated, and working efficiency is increased.
