Title: Four-wheel steering gear for vehicle
Inventor: KANAZAWA HIROTAKA
IPC: B62D7/15
Filed: 1982-10-28
Abstract: PURPOSE:To prevent a vehicle from colliding against a wall and prevent scooping from occurring at the time of rapid braking, by a method wherein a rear- wheel steering angle is set at a zero phase when a front-wheel steering angle is small, and is set to be in a reverse phase when the front-wheel steering angle is large. CONSTITUTION:Front wheels 1, 1 and rear wheels 2, 2 are mechanically separated from each other, an output 4a from a front-wheel steering angle sensor 4 detecting a steering angle thetaH of a steering wheel 3 is inputted into a controller 10 for a rear-wheel steering gear, and the rear wheels 2, 2 are steered by the input signal. The magnitude of the rear-wheel steering angle thetaR relative to the front-wheel steering angle thetaF is enlarged as the vehicle velocity is increased, thereby improving response of the rear wheels to steering of the front wheels, and a steering ratio is reduced as the vehicle velocity is reduced, thereby facilitating turning of direction. In an extremely low velocity range (c), when the front-wheel steering angle thetaF is larger than a predetermined value, it is recognized that the direction of the vehicle is required to be largely changed, and the rear wheels are steered into the reverse phase to facilitate turning of the direction.

IPC: A23L3/18
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To improve sanitary performance, and also preclude the possibility of nonuniformity of sterilization and contamination by inputting powder and grain to a vertical type inverse conical vessel, and pushing up the powder and grain along a vessel peripheral wall part by a spiral ribbon blade. SOLUTION: First of all, steam is introduced to a jacket 6, and a vessel is heated, and powder and grain F to be sterilized is inputted to the vessel, and a temperature is raised up to a prescribed temperature. The powder and grain F is efficiently heated since it is carried upward along a vessel peripheral wall being a heating surface by a spiral ribbon blade 4. When an article temperature of the powder and grain F reaches the prescribed temperature, superheated steam is blown into from a vessel bottom part, and after air in the vessel is substituted with the superheated steam, a valve 8 is closed, and the superheated steam is blown into further, and it is sterilized. When sterilization finishes, the steam in the vessel is exhausted, and a drying hot blast is blown into from the vessel bottom part, and it is dried.  After drying finishes, chilled water is supplied to the jacket 6, and the inside of the vessel is ventilated and cooled, and after being cooled up to the prescribed temperature, it is discharged from the vessel bottom part, and becomes a product.

Title: Manufacture of semiconductor device
Inventor: INUZUKA HAJIME
IPC: H01L21/306
Filed: 1991-07-30
Abstract: PURPOSE:To prevent the emitting intensity of photoluminescence from receiving any adverse effect by forming porous silicon by subjecting single-crystal silicon to an anode formation treatment and removing an oxide film formed on the surface of the porous silicon with diluted hydrofluoric acid. CONSTITUTION:After an aluminum electrode board 2 is put on the rear surface of a p-type single-crystal silicon substrate 1, the substrate 1 and board 2 are coated with wax 3 so that the front surface of the substrate 1 can be exposed. The substrate 1 and board 2 are dipped in 25% hydrofluoric acid 4 and a platinum electrode 5 is also dipped in the acid 4 at the opposite position of the substrate 1. Then the surface of the substrate 1 is subjected to an anode formation treatment by using the substrate 1 as an anode and electrode 5 as a cathode. Namely, the silicon of the substrate 1 is oxidized to SiO2 by active oxygen generated on the surface of the substrate 1 and the SiO2 dissolves in the acid 4. As a result, columnar porous silicon having a pore diameter of about 50Angstrom  is formed on the surface of the substrate. Then the substrate 1 coated with the porous silicon is dipped in 5% hydrofluoric acid for five minutes and a surface oxide film is removed. Therefore, the emitting intensity of photoluminescence can be improved.

Filed: 1986-08-15
Abstract: PURPOSE:To obtain a signal for demodulation which has small jitters and to lower its error rate by performing detection based on either of a leading and a trailing edges in the write direction of pits and reproducing data. CONSTITUTION:When the write direction coincides with the read direction, a write-directional signal 3 and a read-directional signal 4 is equal in logic and the output of an exclusive OR circuit 8 is at a low level.

Title: Atomic absorption photometer
Inventor: SAKAI MASUMI
IPC: G01J1/32
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide an efficient and safety atomic absorption photometer mounting a small and inexpensive power supply in which stability in the brightness of light can be sustained over a wide range of input voltage. SOLUTION: An RCC(ringing choke converter) type switching power supply circuit is employed in the power supply for a light source. When a discharge power supply for HCL(hollow cathode lamp) is employed, the output voltage and the number of turns of secondary winding are high and a high inductance may be produced to disable normal oscillation of a switching circuit. In order to eliminate that situation, the base resistance 37 of a switching transistor 36 is set 3-4 times as high as that being determined according to a standard formula. Since a sufficient base current may not be ensured when the base resistance 37 is increased, a correction control signal is delivered from a switching control circuit in order to ensure a rated output voltage.
