Title: Variable volume type vacuum pump
Inventor: KURIHASHI YASUTAKA
IPC: F04C18/344
Filed: 1983-05-23
Abstract: PURPOSE:To reduce horse power loss in a high rotation range, by a method wherein a vane running-out preventing mechanism, which is actuated when the number of revolutions of a rotor is increased to a given value, is mounted to the side wall of at least a part of vane grooves in which the vane of the rotor is contained. CONSTITUTION:When an engine is increased in a speed and the rotation speed of a rotor 4 exceeds a given value, a vane 5, mounted in a vane groove 12, forms a pump chamber D in cooperation with the vane 5 in the adjoining vane groove 12. In the vane groove 13, a vane slide control probe 15 of a vane running-out preventing mechanism 16 is moved against a spring 14 to bring a wedge-shaped part 17 of the control probe into contact with a wedge-shaped part 18 on the rotor side, and a wedge force is circumferentially exerted to press the vane 5 against a surface 24. This prevents running-out of the vane 5 and prevents formation of a chamber D necessary to a pump action, whereby, during high speed operation, a pump volume is decreased to 1/4 a pump volume per one full rotation prevailing during low speed rotation.

Title: Grounding load control device
Inventor: IZAWA MASAKI
IPC: B60G17/015
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of one-side braking at the time of braking, and to shorten the braking distance by generating an acceleration in an actuator of a tire having a low friction coefficient, which is provided between a car body and an axle, and increasing an apparent load to be applied to a tire. SOLUTION: In the case of one-side braking condition, a temporary target load is generated on the basis of the signal from a sprung acceleration sensor 22 and an unsprung acceleration sensor 23, which are input into a target load computing unit 24, and a deviation between the computed value and the signal from a load sensor 20 is computed, and processed by a stabilizing computing unit 25, and thereafter, a displacement limiting and comparing computing unit 26 adjusts a command value to be given to a servo valve driver so that control within a limit of the stroke of an actuator 5 is performed on the basis of the signal from a stroke sensor 21.  A servo valve 10 is driven on the basis of the adjusted signal, and the actuator 5 generates the stroke so that a target load and a real load coincide with each other, and vertical acceleration in a direction for increasing the tire grounding load is generated.

Title: Data element prefetching method
Inventor: EDWARD H GORNYSH
IPC: G06F9/45
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a compiler which efficiently and effectively prefetches data reference when a plurality of loops in a nested loop structure are different in advanced direction. SOLUTION: As a first approach, one or a plurality of loops are inverted so that reference is in the same direction. When the loops are inverted, a data element can be prefetched in a common loop direction. An internal loop is preferably inverted to an external loop, which may be inverted. When there are more than one reference direction and the loops can not be inverted, a 2nd approach is used. In this case, a prefetching is performed in the opposite direction from the innermost loop.

Title: Tablet type dehumidifying agent
Inventor: TAKAHASHI YUKIO
IPC: B01J20/28
Filed: 1988-04-13
Abstract: PURPOSE:To prevent a wide variance of compressive breaking strength even in a successive tableting operation and the occurrence of an easily breakable tablet, by using the sodium diphosphate or sodium pyrophosphate of a specific water content as a hydroscopically effective component. CONSTITUTION:Granulated sodium diphosphate or anhydrous sodium pyrophosphate is sprayed with water to form a mixture of the water content of 0.5-20wt.%. This powder is thereafter mixed with lubricant and successively formed using a tableting machine into a hollow cylindrical shape of dehumidifying tablet. Since such dehumidifying agent can retain the moisture absorbed from the surrounding air as water of crystallization, there is no possibility of the deliquesced liquid being escaped and also the lowering of yield rate of the tablet due to its easy partial breakage can be prevented.

Title: Engine decompression device
Inventor: YAMAGUCHI YOSHINOBU
IPC: F01L13/08
Filed: 1984-05-07
Abstract: PURPOSE:To make the rotational speeds of decompression release and engagement different without requiring the elastic deformation of a hook by changing the mass of the weight that actuates the decompression cam by use of a centrifugal force-dependent hook. CONSTITUTION:An arrangement is made such that a decompression cam 4 is actuated by a decompression weight 6, and an auxiliary weight 9 is provided. Both the weights are connected in one unit by a hook 10 that is biased to contact the decompression weight 6 by a spring attached to the auxiliary weight 9. When the normal operating speed is reached after an engine startup, the hook 10 moves outwardly by centrifugal force to separate the weights 6, 9. Due to the fact that the mass of the centrifugal weight actuating the decompression cam 4 is reduced, the decompression mode is assumed even at a high speed, ensuring the engine stoppage in a deceleration mode. Since there is no deformation to the hook, its durability is enhanced.

Abstract: PURPOSE: To prevent the danger of ignition, etc., by storing a temperature ripple in the contact state of a temperature detecting means (thermistor) and comparing the. stored temperature ripple with the calculated temperature ripple for judging the contact state of the thermistor. CONSTITUTION: A printer control layer 24 is connected to a host computer 25 being an external device with an interface 26 and receives image information, to control the drive of a laser unit 12, etc., and further, the drive of a sequence of printing operations overall. At the time of judging the contact state of the thermistor 14d, a temperature ripple value is calculated with the detected temp. and the calculated ripple value is compared with a reference value of the temperature ripple value in the contact state of the thermistor 14d which is stored in advance. When it does not appear that the fact that the thermistor 14d is away from a heating roller 14a is judged, in the case the calculated temperature ripple value exceeds the reference value, it is judged that the thermistor 14d is in the contact state.

Title: Radiant tube burner
Inventor: KAWAMOTO MASAO
IPC: F23D14/12
Filed: 1988-04-14
Abstract: PURPOSE:To obtain the title radiant tube burner of low NOX by lowering the temperature of a flame in a primary combustion region and performing a low air ratio combustion in a secondary combustion region. CONSTITUTION:A large quantity of combustion air corresponding to the total quantity of combustion air injected into a primary combustion chamber 6 and a small quantity of a primary fuel which is a part of a fuel are rapidly mixed, and the mixed fuel burns under a high air ratio at a high load to form a flame which reaches an outlet of a primary combustion chamber 6 within a furnace 14 from the bank of a radiant tube 1 and to cause a secondary combustion of a low air ratio between the combustion air and a secondary fuel fed into the radiant tube 1. Accordingly, the temperature of a flame is low in the primary combustion region and a low air ratio combustion is performed in the secondary combustion region, and hence the quantity of generated NOX can be suppressed to a low value as a whole. Further, since a primary fuel nozzle 4 is located out of a combustion gas discharge route and a second fuel nozzle 7 is encircled by a refractory material 17, the combustion nozzles 4 and 7 are prevented from burning or the fuel is prevented from coking.

Title: Photoelectric position locator
Inventor: OOHASHI YOSHIHARU
IPC: G01B11/00
Filed: 1978-07-26
Abstract: PURPOSE: To improve the detecting accuracy by using a power source for a spot light source, which rises in response to any command signal to monotonously increase when the output current of a position locating element reaches a preset value.  
     CONSTITUTION: Simultaneously as an integrating device 6 is reset in response to the pulses from a clock pulse generator 7, a pulse generator is set to raise the pulses from a terminal Q. Then, a lamp voltage is fed from the integrating device 6 through a switch 81 to an amplifier 91 so that the amplifier 91 feeds an LED 101 with a current corresponding to the input voltage to monotonously increase its brightness. Since the output current of a position detecting element 1 is also monotonously increased in accordance therewith, this current is converted into a voltage which is fed to a comparator 4. When a standard voltage is reached, pulses are fed to the terminal R of a generator 5 and to the control terminal of a switch 32 thereby to break the pulses from the terminal R. Then, the output of the device 6 stops its increase at that level to hold the maximum brightness of the LED 101. Thus, it is possible to enhance the detecting accuracy while eliminating the distortion in the position.
