Title: Hunting checking circuit of construction machine
Inventor: HIROTA KENICHI
IPC: F15B11/028
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To inexpensively provide a circuit which quickly checks hunting when hunting occurs with a spool in a directional control valve vibrated during operation of an actuator for a construction machine. SOLUTION: A pressure detecting part 17 is provided at a hydraulic line 8 at the bottom side of a boom cylinder 10. Detection signals from the pressure detecting part 17 are inputted into a control part 3 and changes of pressure PB at the bottom side of the boom cylinder 10 are seized at the control part 3. When a spool of a directional control valve 7 vibrates in the direction (a-b) during operation for lowering the boom, changes of pressure PB at the bottom side of the boom cylinder 10 is detected with the pressure detecting part 17, and the control part 3 makes judgement for the direction of movement for the spool of the directional control valve 7, depending on whether the bottom- side pressure PB is increased or decreased.  Then, the control part controls the secondary pressure of a solenoid operated proportional value 4, namely pilot pressure P1 of the directional control valve 7, so that the movement of the spool of the directional control valve 7 can be offsetted.

Title: Suspension control device
Inventor: YOKOTE MASATSUGU
IPC: B60G17/0185
Filed: 1988-12-28
Abstract: PURPOSE:To ensure driving stability even at a decreased air pressure in a tire while turning by arranging a tire air pressure detecting means which detecting each air pressure in the tires of front and rear wheels, and a wheel load changing means which changes the wheel load of a given wheel through a wheel load adjusting mechanism according to detected air pressure. CONSTITUTION:Tire air pressure P1 - P4 and lateral G are read by respective tire air pressure sensors 27 - 30 and a lateral acceleration (lateral G) sensor 31, and as turning driving when lateral G is beyond prescribed level G0, the wheel loads of right and left rear wheels are relocated so that the wheel load of a rear outer wheel may increase with the decrease in the air pressure of a front wheel tire if at least either of air pressure P1 or P2 of a right or left front wheel tire is under an abnormal condition of air pressure in the front wheel tire. When both air pressure P1 and P2 are beyond a prescribed level and air pressure P3 or P4 in a right or left rear wheel tire is under an abnormal condition of air pressure in a rear wheel tire which is below the prescribed level, the wheel loads of right and left front wheels are relocated so that the wheel load of a front outer wheel may increase with the decrease in the air pressure of a rear wheel. This makes a correction so that the steering characteristics of a vehicle may be neutralized.

Abstract: PURPOSE:To prepare cooked rice packed in a bag and having improved palatability, taste and long-term preservability at normal temperature by adding an edible oil to water-containing rice grains, putting the rice and a specific conditioning liquid into a heat-resistant bag, deaerating and sealing the bag, heat- treating the bagged rice and cooling the product. CONSTITUTION:A conditioning liquid is prepared by dissolving 0.1-0.6wt.% of food vinegar, 0.1-0.6wt.% of sugars and 0.03-0.08wt.% of common salt in water and, as necessary, adding 0.4-0.8wt.% of starch (e.g. tapioca starch) and 0.03-0.08wt.% of a starch decomposition enzyme such as amylase. Stock rice is washed with water, immersed in water of about 20 deg.C for 30-200min and drained to obtain rice grains having water-content of 20-25%. The rice grains are mixed with 0.2-4.0wt.% of an edible oil (e.g. salad oil). The oil-mixed rice grains are charged together with 90-110wt.% of the above conditioning liquid into a heat-resistant bag, deaerated, sealed, subjected to vibration treatment, heated at 90-100 deg.C for 60-90min and cooled to obtain the objective bagged rice.

Title: Method for pulling up silicon single crystal
Inventor: BUIRUFURETSUDO FUON AMON
IPC: C30B29/06
Filed: 1994-12-06
Abstract: PURPOSE: To obtain a method for pulling up a silicon single crystal by the Czochralski method by which the lower limit of the pulling up speed Vcrit, at which a laminated defective ring starts to appear, is raised by pulling up the single crystal at a specific speed.  
     CONSTITUTION: The silicon single crystal pulling up method, by which a silicon melt housed in a crucible is pulled up in the vertical direction thereof at a specific speed, is executed by pulling up the crystal at a speed not exceeding a maximum pulling up speed which is approximately in proportion to the temp. gradient (G) in the boundary region of the solid phase/liq. phase of the growing single crystal. Preferably, the crystal is pulled up at the maximum speed calculated by empirical formula Vcrit (cm×min)=f×G (f is proportion factor, 13×10 -4  cm 2 /K(°C).min; the unit of G is K(°C)/cm). In order to increase the maximum pulling up speed, the temp. gradient of the growing single crystal is increased by using a shield which thermally covers the single crystal. When the shield is positively cooled, the temp. gradient is further increased. The use of the blacking-treated shield is advantageous.

When the amount exceeds 50mol%, obtained rubber becomes hard and brittle. As addition agent, which constitutes the silicone rubber part for a printer head together with silicone rubber; filler, pigment, heat-resistance improving agent, adhesion aiding agent, flame retarding agent and the like can be used. The manufacturing method of the silicone rubber part for the printer head is as follows: the silicone rubber constituting materials are heated or compressed so as to form a desired shape, and the materials are hardened.

Abstract: PURPOSE:To utilize the system even for satellite transmission with a tight limit in the band and the C/N by limiting an instantaneous dynamic range of a modulation signal in advance so as to attain polyphase PSK modulation in excess of 360 deg.. CONSTITUTION:A through-rate limit circuit 1 limits the amplitude of a difference signal between samples, an amplitude angle conversion circuit 2 limits a phase change between samples in the poly phase PSK modulation such as 256 phase PSK within 360 deg. so as to allow a phase rotation number discrimination circuit 32 at the demodulator side to discriminate on how many circulations on a circle of 360 deg. a current sample is located.

Abstract: PURPOSE:To make it possible to secure the accuracy of detected temperature for a long period by providing a switching element on a current conducting path for thermistor, closing the switching element in synchronization with the temperature detecting period of a body to be heated with a tuning and conducting means. CONSTITUTION:Fuel oil which is sent into a carbureter 1 with the pressure of a pump 16 is heated and vaporized, and the vaporized gas is obtained. The gas is jetted into a burner 19 through a nozzle 18 and burned. At the this time, the temperature of the vaporized gas affects the quality of the burning. Therefore, the temperature of the carbureter 1 required for conducting the specified operation is detected by a control means 3. Then, a transistor 13 is closed by the operation of a tuning and conducting means 15. The voltage corresponding to the resistance value of a thermistor 9 undergoes A/D conversion 12, and the digital value is read by a detecting means 14. Thus, the temperature is detected. When the detection is completed, the means 15 stops the operation. The series of the operations are stopped in a short time, and the integrated current conduction time is shortened. The characteristics of the resistance values are hardly changed. The accuracy in detected temperature is kept for a long period, and the excellent burning is continued.
