Title: Negative pressure type floating head slider
Inventor: SUZUKI SHIGEHISA
IPC: G11B21/21
Filed: 1985-07-05
Abstract: PURPOSE:To improve the reliability by forming a cross rail to be recessed deeper than the floating face of both side rails so as to reduce the generation of suction force. CONSTITUTION:The cross rail 11 formed to be recessed deeper than the floating face 3 of both the side rails 2 as a whole between the rails 2 and reducing the air flow going to the downstream is provided to form the air flowing-in face 12 of the cross rail 11. When air flow flows in the arrow U direction with a negative pressure slider, the positive floating force is generated to a taper face 7 and the floating face 3 and the negative suction force is generated to a negative pressure face 12. Spring force F by a spring 10 is exerted externally so as to withstand the sum of the fluid forces, resulting that the fluid force of positive and negative pressure and the spring force are balanced automatically. In setting the value of a step H to a proper value (normally 0-1mum), the head slider is made stable and the collision between the cross rail 11 and projection or dust on the surface of a recording medium hardly takes place.

Title: Method for heating greenhouse for protected horticulture
Inventor: KAMANAKA RYUSUKE
IPC: A01G9/26
Filed: 1992-05-15
Abstract: PURPOSE:To efficiently use an oil burning heater corresponding to a heating load together in a heat pump capable of heating a greenhouse for protected horticulture with underground water as a heat source. CONSTITUTION:The required heat quantity of a greenhouse is calculated on the basis of the minimum value of the outside air temperature at the site of the greenhouse and a heat pump part (H) is combined with an oil burning part (N) so as to provide 1:(1-3) burden ratio of the heat quantity for the heat pump part and the oil burning part. One day is separated into plural time zones and the set room temperatures to be maintained in the greenhouse (31) in the respective time zones are determined to monitor the room temperature with an operation control panel (19) integrated with the heat pump part (H) and the oil burning part (N). At the time of a light load at a slightly high outside air temperature, only the heat pump part (H) is operated to maintain the set room temperatures. When the outside air temperature is further lowered to increase the load and the set room temperatures cannot be maintained only with the heat pump part (H), the oil burning part (N) is additionally operated if the room temperatures are further lowered from the preset temperature range.

Title: Constant voltage circuit protected from short-circuit
Inventor: MURASHIGE SHINICHI
IPC: G05F1/573
Filed: 1981-09-19
Abstract: PURPOSE:To stabilize a circuit with simple constitution, by turning off a controlling transistor TR to prevent the breakdown of circuit elements due to the overload when the load is short-circuited and resetting the controlling TR automatically when the abnormality in the load side is released. CONSTITUTION:An operational amplifier 2 amplifies the difference between a reference voltage VZ and a divided voltage Vd and adjusts the base current of an output voltage controlling TR1 through a resistance 6 to secure a constant voltage V against the variance of the load. Even if the voltage Vd drops toward 0 because of the short-circuit of the load, the amplifier 2 reaches a shift voltage VA just before Vd=0. Since the voltage VA is lower than the voltage VZ, the output is inverted to the H level quickly to turn off the TR1 quickly. The voltage Vd becomes 0 thereafter, but the TR1 is kept in the turning-off state because the amplifier 3 is driven to a displacement area, and thus, the breakdown of elements is prevented.

Title: Image monitoring system
Inventor: YASUDA AKIRA
IPC: H04N7/18
Filed: 1986-06-25
Abstract: PURPOSE:To detect a change in an image, without delaying from a detection action by a sensor, by stopping an action for detecting a change in an image or invalidating an output detecting said change so as only to update a reference image when a sensor does not detect a change and executing the action for detecting a change in an image or validating the output detecting said change when the sensor detects a change. CONSTITUTION:An image comparator 7 detects the difference between a current image and the reference image corresponding to a corresponding image pickup camera 1. If the change is detected, the image whose change is detected is transmitted to an abnormality decision circuit 9 through a reference image update circuit 8. When the change is detected, the reference image update circuit 8 updates image data in a reference image frame buffer 6 with the currnet image as the reference image. This update is always executed even if the sensor 2 does not detect the change. The abnormality decision circuit 9 decides the size of the detected change, and if it exceeds a reference value, the circuit 9 decides that there is an abnormal change, generates a detection output and operates an alarm processing circuit 10. The output detecting the abnormal change is validated only when the detection signal of the sensor 2 is inputted.

Filed: 1993-05-27
Abstract: PURPOSE:To effectively remove fine particles in gas by using the back pressure caused on the rear of a rotating impeller to generate fine bubbles of fine particle-contg. gas and making the fine particles in the gas remain in the liquid. CONSTITUTION:A rotating shaft 22 is rotated by the operation of a driving motor 28 of a gas-liquid mixer 20. In this way, an impeller 21 is rotated in liquid to generate a vortex, allowing negative pressure in liquid on the rear of the impeller 21 in the rotating direction to be caused. And fine particle-contg. gas is mixed in the vortex through a gas introducing pipe 27 connected to a cylindrical body 26. Then, the mixed dust-contg. gas generates a lot of fine bubbles in liquid by shear force between the vortex and impeller and rises in a state in which the contact between the liquid and the fine particles is increased. In the rising process, the fine particles are collected by the liquid and the purified gas is discharged from a gas outlet 12.
