Title: Sequence controller
Inventor: UEDA KAZUYOSHI
IPC: G05B19/08
Filed: 1979-03-06
Abstract: PURPOSE: To ensure the start in the state before the service interruption even after recover of the service interruption as sell as cause no trouble at all for the progress of the load process even at the time of service interruption, by memorizing at all times the digital signal of the counter output with the contact state of the contact magnetism holding relay.  
     CONSTITUTION: The count signal (digital signal) sent from the counter is supplied to the matrix circuit via the decoder and then controls the load based on the program which is set up by the diode connection. At the same time, the ON exciting coil of the contact magnetism holding relay is connected to the counter output terminal along with the OFF exciting coil via the NOT circuit. Thus both "0" and "1" of the digital signal are memorized via the intermittence of the relay contact regardless of occurrence of the service interruption. If this intermittence of the relay contact is actuated as the switch element of the preset input of the counter, the counting state of the interruption time can be reset when the service interruption is recovered.

Title: Input buffer circuit
Inventor: SATO MITSURU
IPC: H03K19/0185
Filed: 1991-01-28
Abstract: PURPOSE:To realize the input buffer circuit able to prevent a through-current and a change in an input threshold level due to a change in a power supply voltage or a temperature. CONSTITUTION:An N-channel MOS TR N1 outputs a low level to an inverting output terminal OUTB when an input terminal IN is at a high level. In this case, an inverter circuit comprising TRs P2, N2 outputs a high level to a noninverting output terminal OUTA. An N-channel MOSTR N4 outputs a low level to the noninverting output terminal OUTA. In this case, an inverter circuit comprising TRs P3, N3 outputs a low level to the inverting output terminal OUTB. No through-current flows between power supplies because of the bistability of the flip-flop circuit. A change in the input threshold level due to a change in a power supply voltage or a temperature is prevented in response to a reference voltage at a reference voltage input terminal VR.

Abstract: PURPOSE:To avoid the wasteful consumption of a recording medium such as recording papers by printing picture information sent from an already registered party as soon as it is received, once storing the picture information sent from an unregistered party, confirming the picture on a display device, and then selecting whether or not it is printed. CONSTITUTION:A MODEM 12 extracts an origin of call ID out of the reception signals, when the decision result of the ID is 'registered', it is supplied to a printer 14, immediately printed, and a hard copy 15 is obtained. When the ID decision result is 'unregistered', the received information is inputted and written from the MODEM 12 through a switching part 20 to a picture memory 16, and temporarily stored in the memory 16. The picture of the information stored into the picture memory 16 is displayed on a display device 18 according to a command input from an operating part such as a keyboard. An operator observes the displayed picture, judges whether the information is necessary or not for hard copying, and inputs a printing command or an erasing command.

Title: Body detector for automobile
Inventor: SERA YOSHIYUKI
IPC: G01V3/08
Filed: 1990-02-08
Abstract: PURPOSE:To detect the presence of a body to be detected when an automobile is re-started by providing an alarm storage means which stores the occurence of an alarm when the automobile is stopped at a time when the alarm is issued due to the presence of the body to be detected, and an operation detecting means, etc. CONSTITUTION:When the automobile is re-driven, a key switch is turned on, and the body detector for automobile is re-started. Such re-start is detected with a re-start detection circuit 16, and a detection signal is inputted to an AND circuit 18 as a HI signal. At this time, since an alarm memory circuit 17 already outputs the HI signal to the circuit 18, the output of the circuit 18 goes to the HI signal, and the alarm is issued from an alarm 8 via an OR circuit 11. After that, when the body starts to move from such state, a discriminator 10 commands the occurrence of the alarm when the body approaches the detecting range of a sensor 3. When a speed sensor 12 detects the travel of the automobile, the output of a stoppage detection circuit 13 is sent from the HI signal to the alarm memory circuit 17 via a LO circuit 15, then, storage is cancelled.

Abstract: PURPOSE:To prevent the magnetic sound of a motor from increasing and to convert the sound into a convenient sound by differentiating a carrier frequency for PWM control of PWM power converters respectively provided for a plurality of motors for supplying variable voltages in predetermined relationship. CONSTITUTION:An induction motor 2A is driven with VVVF AC inverted from a DC power source 3A by an inverter 1A. The output of a speed command circuit 8A is V/F-converted by a V/F converter 7A, and input to a voltage command circuit 6A. The circuit 6A generates voltage command patterns having a phase difference of 120 deg., which are compared with an output f1 of an oscillator 5A for generating a carrier signal by comparators 9B-11B to form a PWM signal, thereby controlling switching elements TUP-TWN via a gate 4. Other motors 2B, 2C are controlled entirely similarly, but carrier frequencies f1-f3 are combined to form a chord. Thus, electromagnetic sounds generated from the motors 2A-2C are simplified, not amplified, and converted into convenient sound.

Abstract: PURPOSE:To make it possible to completely decompose smoke generated at the time of heating and to reduce smoke at the time of cooking by forming a heat resisting film containing an oxidation catalyst such as hydrocarbon or the like on the surface of a metal base material which is a secondary radiant body. CONSTITUTION:A metal base material of a steel-shape or a plate-shape having an opening is used as a secondary radiant body is employed, and a heat resisting film containing an oxidation catalyst such as hydrocarbon or the like is formed on the surface of the metal base material. As an oxidation catalyst a composite metallic oxide having a provskite structure of ABO3 is used. Smoke generated at the time of cooking almost contains an unsaturated fatty acid of 18C and a mixture thereof. At portion of the secondary radiant bode of the grill having a temperature close to 1,000 deg.C, the smoke is cut into 1C-3C, and completely oxidized by the oxidation catalyst, whereby purification of the smoke can be carried out. In order to sufficiently achieve the function of the oxidation catalyst, a paint essentially composed of an organic SiC polymer is used as a binder. When the paint is sintered at a temperature of 600 deg.C or more, the film of SiC produced is extremely porous and excellent in heat resistance, and hence thermal deterioration of the metal base material which is used as a can be prevented.
