Title: Sensor for dry-cleaning detergent concentration and control method therefor
Inventor: TAKI YUKIO
IPC: G01N27/02
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To enable the measurement of concentration from both data on impedance obtained by impressing an a.c. voltage between a plurality of electrodes immersed in a cleaning liquid and data on the temperature of the cleaning liquid obtained by a temperature sensor. SOLUTION: In a concentration sensor 1, an electrode 3 is concentrically fixed in a cylindrical external electrode 2, and a temperature sensor 4 is protruded from the center of the internal electrode 3. A dry-cleaning cleaning liquid is contained between the electrodes 2 and 3, and capacitance occurs there. This capacitance is measured to obtain the concentration of a detergent from changes in capacitance. As the relation between capacitance and concentration differs according to temperature, the temperature sensor 4 is provided for measuring the temperature of the cleaning liquid to perform compensation by temperature. Any element whose resistance and electromotive force change by temperature may be used for the temperature sensor 4. The terminals at both ends of the sensor 4 are extracted to the outside by lead wires 18 and 19.  A thermistor is a semiconductor temperature measuring element whose resistance decreases with the increase of temperature.

Title: Calling system
Inventor: TOMIFUJI YASUKI
IPC: H04B7/26
Filed: 1991-12-12
Abstract: PURPOSE:To effectively utilize a communication line by detecting a level of a reception electric field strength at a mobile station side, making a call when the electric field strength is a prescribed level of over and inhibiting calling when the level is a prescribed level or below. CONSTITUTION:A mobile station radio equipment 4 of a mobile station 3 receives a transmission radio wave from a command station 1 directly or the transmission radio wave from the command station 1 via a base station 2 and outputs the radio wave to an in-zone detection means 5. The means 5 detects whether or not the station 3 is resident in the communication zone of the radio wave sent from the command station 1 or the base station 2, and the means 5 measures the reception electric field strength by a reception electric field strength level detection means 6 when the station stays in the zone. A call operation control means 7 discriminates whether or not the electric field strength level is a prescribed level or not based on the output of the means 6 and stops the calling when the level is a prescribed level or below. Thus, since no calling is made when the station 3 enters a tunnel or a shadow of a building or the like and the electric field strength is low, the probability of failed data communication is reduced.

Abstract: PURPOSE:To reduce the number of times of carrying out brake fluid pressure control and lighten the burden of a brake by setting the threshold value which is the condition of starting/finishing brake fluid pressure control executed to restrain slippage higher as vehicle speed gets higher. CONSTITUTION:The output signals of a driving-wheel speed detecting means 17A and a driven-wheel speed detecting means 17B are inputted into an arithmetic circuit 16A, where the existence of slippage is judged from the difference between the driving-wheel speed and the driven-wheel speed. When the occurrence of slippage is detected at the time of starting or accelerating a vehicle, an engine output control means 15A and/or a brake fluid pressure control means 16B is controlled to restrain the slippage. In such a propulsion force control method, a threshold value which is the condition of starting/finishing brake fluid pressure control is set higher as the vehicle speed gets higher. Thereby, the speed difference taken into the brake fluid pressure control is made larger as the vehicle speed gets higher, to reduce the number of times of carrying out brake fluid pressure control and lighten the burden of the brake.

Title: Semiconductor integrated circuit
Inventor: DOUGASAKI SHIKO
IPC: H03K17/16
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To reduce futile power consumption with a constitution where CMOS circuits to be operated by different power sources are connected to each other. SOLUTION: An AND gate 25 is provided in an RTC circuit 2, and the output is used as the inner signal 26 of the RTC circuit 2. When an RTC control circuit source 5 is turned off, a reset signal 8 is fixed to 'L' and the inner signal 26 to 'L'. Thus, conventional pull down resistance is unnecessitated. Even if the signal 6 of an output buffer 24 is 'H', unnecessary power consumption is not generated in the RTC control circuit power source 5. When only the RTC control circuit power source 5 is turned off, the voltage of the RTC control circuit power source 5 gradually drops and becomes 'L'. Even if the signal 6 of the output buffer 24 is 'H', the reset signal 8 becomes 'L' when the voltage of the RTC control circuit power source 5 becomes lower than a prescribed level. Thus, the inner signal 26 becomes 'L' and through current does not flow through the RTC circuit 2.

Title: Multistage rolling device
Inventor: KYOYA MITSUO
IPC: B21B39/00
Filed: 1989-12-21
Abstract: PURPOSE:To change the position in the backward and forward direction of material to be rolled in a small space by constituting a rotary conveyer so that the middle in the carrying direction of carrying part is rotatable and both end parts in the carrying direction of carrying part are bendable and stretchable downward or upward. CONSTITUTION:When a material to be rolled is moved on the rotary conveyer 15 with each conveyer, the movement by each conveyer is once stopped. After that, both end parts of carrying part 17 are bent. Then, since both those end parts don't hit the end part of other conveyers even if the carrying part 17 is revolved, the longitudinal direction of the material to be rolled is reversed by revolving the carrying part 17. In this manner, after both end parts of the carrying part 17 is stretched when the revolution is completed, the material to be rolled is moved in the same direction as the previous direction by starting the rotary conveyer 15 and other conveyers again. In this way, the longitudinal direction of the material to be rolled which is entered into a rolling mill can be changed every time.
