Title: Capacitance detection circuit for capacitive sensor
Inventor: UMEDA FUMIHIKO
IPC: G01P15/125
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a capacitance detection circuit in which the sensitivity can be enhanced essentially using an integrating circuit. SOLUTION: A resistor element R is connected in series with a capacitance Cv between a movable electrode and a fixed electrode of a capacitive sensor and a diode D is connected in parallel with the resistor element. A driving voltage (rectangular wave) Vin for detection is applied to the open end of the resistor element. The capacitance is charged at a time constant RC when the driving voltage rises and discharged instantaneously through the diode D when the driving voltage falls. Since the fluctuation in the capacitance Cv has an effect on the output from the integrating circuit only on the rising side of the driving voltage, the sensitivity is not canceled from the falling side resulting in the enhancement of the sensitivity.

Title: Production of high strength hot-rolled steel plate excellent in stretch-flanging property
Inventor: YOSHINAGA NAOKI
IPC: C22C38/06
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To reduce the unevenness of strength and stretch-flanging property by regulating chemical components and hot-rolling condition. SOLUTION: Silicon is the most important element and acts to restrain the precipitation of cementite harmful to the stretch-flanging property. When 0.04-0.07wt.% of C concn. range, and 1.0-1.4wt.% of So concn. range, the above restraining effect is remarkable. Finish-rolling is executed at a temp. above the Ar3 transformation point or higher. The stretch-flanging property is improved by the above operation because the recrystallization and granulation of γ till starting the cooling are progressed and Ar3 point at the time of cooling after rolling is lowered to make fine the structure of a product plate. Therein, the coiling temp. is particularly important, and when it is in the range of 400-600 deg.C, the accuracy to hit a coiling temp., is increased and the unevenness of the strength and the stretch-flanging property are reduced.

Title: Stench reducing unit for car air conditioner
Inventor: OOSAWA HIDETOSHI
IPC: B60H3/00
Filed: 1981-12-07
Abstract: PURPOSE:To prevent a stench from being scattered in a car room when ventilation is started by connecting joints of bypassing paths that bypass a heat exchanger to a main air path, respectively, and on-off controlling dampers by the temperature of the heat exchanger. CONSTITUTION:The temperature of a heat exchanger 3 is detected by a temperature detector 6 and is input to a controller 7. The controller 7 controls dampers 5A and 5B in the direction where a main air path 2 is closed until the detecting temperature of the detector 6 arrives at preset temperatures, for example, 15--10 deg.C or less. Thus, the air flow passes through a bypassing path 4 and does not pass through the heat exchanger 3. A stench that adhered to the heat exchanger 3 is not scattered in a car room. When the temperature of heat exchanger 3 drops below a preset level, the moisture in the air is dew-condensed and adheres to the heat exchanger 3, thus the stench that adhered to it is not scattered in the car room. As a result, the stench can be prevented from being scattered in the car room when air conditioning is started.
