Title: Method for discriminating shape of rolled steel plate
Inventor: ASANO SHIGERU
IPC: G01B7/00
Filed: 1985-03-29
Abstract: PURPOSE:To prevent a rolling trouble by correcting a tension distribution signal by a gap signal to discriminate the potential shape of a steel plate and discriminating the sensible shape of the steel plate when the gap signal increases to a permissible value or above. CONSTITUTION:A magnetic permeability sensor 1 is installed to the bottom surface of the steel plate P and is traversed in the transverse direction of the steel plate. The shape of the steel plate is discriminated from the tension distribution signal S1 and the gap signal S2. The tension distribution signal S1 and the gap signal S2 are sampled. The signal S2 is nearly a square wave as shown by a solid line when the shape of the steel plate is potential. The signal is the wave shown by a broken line when, for example, the middle waviness is sensibly formed. The tension distribution signal S1 is corrected by the gap signal S2 and the potential shape is discriminated if the shape is potential. The sensible shape of the steel plate is discriminated when the gap signal S2 increases to the permissible value or above. The shape adjustment of rolls, etc. are executed from the results of such discrimination so that the results of the discrimination are reflected in the actual control.

Title: Vehicle air conditioner
Inventor: HARA TOSHIZOU
IPC: B60H1/32
Filed: 1981-04-30
Abstract: PURPOSE:To make it possible to smoothly accelerate by increasing the on-and- off set value of a thermoswitch circuit by a constant one within the range of the set value of a timer triggered by means of a load signal in air conditioner controlling a compressor by evaporator temperature. CONSTITUTION:The load state of an engine is detected by a pressure switch 2. Here, closing the switch causes a trigger pulse to be produced in an inverting circuit 3 and a differentiating circuit 4, allowing the pulse to enter a timer circuit 5. Hereby, a pulse width signal having the set time T is entered the non- inverting input side of an operational amplifier 28 in a thermoswitch circuit 6 to raise the input voltage by time T, that is, to increase the on-and-off set level by a constant value. Consequently, since compressor stoppage by a sensor 8 is quickened when evaporator side temperature is reduced, acceleration and slope- climbing are smoothly performed. Furthermore, when evaporator surface temperature reaches the set level, the compressor is automatically restored so that the rising of car room temperature can be prevented.

Title: Optical information reproducing device
Inventor: ISAKA HARUO
IPC: G11B7/09
Filed: 1983-04-14
Abstract: PURPOSE:To make stable tracking control against a disk defect possible, by producing a reference signal which produces an appropriate level between a level corresponding to the maximum value of quantity of light detected by an optical head out of reproduced signals and another level corresponding to the minimum value and fetching a difference signal by subtracting a reference signal from the reproduced signals. CONSTITUTION:An error detecting circuit 9 extracts a tracking error signal. Under a normal operation, the tracking error signal passes through a signal processing means 10 under the same condition and operates an actuator 12 so as to deny a tracking error after it is power-amplified by a driving circuit 11. Thus tracking control is performed. On the other hand, when some information signals are missed or a disk is under defected condition, a disk defect detect signal is outputted from a defect detecting means equipped with a reference signal producing means 14, subtracting means 15, rectifying means 16, high-pass filter 17, etc., and, during the period when the disk defect detect signal is outputted, the signal processing means 10 performs processing, such as holding of a tracking error signal just before the defect occurs, interruption of high order components contained in the tracking error signal, etc., so as to prevent the tracking control from being disturbed by noises contained in the tracking error signal.

Title: Valve timing controller for alcohol engine
IPC: F02D19/08
Filed: 1992-03-25
Abstract: PURPOSE:To reduce fuel consumption without deteriorating combustibility by enlarging the valve overlapping period of an intake valve and the exhaust valve and increasing the internal EGR amount for reduced pumping loss when alcohol concentration in fuel is high. CONSTITUTION:The alcohol engine 1 uses fuel including alcohol, and is provided with a valve timing variable means which makes the overlapping period of an intake valve 5 and an exhaust valve 6 variable. In this case, alcohol concentration in fuel is detected by an alcohol concentration detecting means. When the detected alcohol concentration is high, a valve timing control means controls the valve timing variable means so as to make the overlapping period longer. It is thus possible to reduce fuel consumption without deteriorating combustibility by increasing the internal EGR amount for reduced pumping loss when alcohol concentration in fuel is high.
