Title: Four-wheel drive vehicle
Inventor: WATANABE JUN
IPC: B60K17/356
Filed: 1996-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a dead zone in advancing, eliminate it in retreating, and effectively transmit a driving force to a road surface by the four wheels from the initial stage by setting the product of a pump intrinsic discharge and a drive gear ratio to smaller than the product of a motor maximum intrinsic discharge and the drive gear ratio, and setting the former to equal to the latter or larger than the latter in retreating. SOLUTION: A four-wheel drive vehicle is provided with a front wheel shaft 4 driven by a main prime mover 1, a pump driven via a gear 9, a variable displacement motor which is connected to the rear wheel shaft 7 via a gear 10 and driven according to fluid pressure from the pump, and an oil path for connecting a discharge port and an inlet mutually. In advancing, it is set to a pump intrinsic discharge × a pump drive gear ratio < a motor maximum intrinsic discharge × a motor drive gear ratio, and in retreating, it is set to a pump intrinsic discharge × a pump drive gear ratio >=a motor maximum intrinsic discharge × a motor drive gear ratio.  A dead zone is thus provided in advancing so as to prevent fuel consumption from being deteriorated caused by a deformed tire, eliminate the dead zone in retreating, and transmit the drive force effectively to the road surface by the four wheels from the initial stage.

IPC: G01B11/245
Filed: 1984-04-28
Abstract: PURPOSE:To measure a sectional shape without any mechanical scan by emitting a radiation at a specific angle in the breadthwise direction of a body to be measured and arranging a multichannel radiation detecting means for the body to be measured. CONSTITUTION:The multichannel X-ray detector 22 and an X-ray generator 21 are installed on upper and lower frames 20b and 20a of a U-shaped frame 20, the body to be measured S is allowed to run between both frames 20a and 20b, and X rays are emitted by the generator 21 at the specific angle including the body S to be measured in the breadthwise direction of the body S to be measured.

Title: Feedwater deaerator of steam plant
Inventor: OKADA NOBUYOSHI
IPC: F22D11/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To effectively utilize a plant installation space and to reduce device costs by connecting a water pipe for supplying replenishment water for a boiler, by mixing the replenishment water with bypass steam, and deaerating the replenishment water. SOLUTION: Steam that is branched from a main steam pipe 21 and is guided to a bypass steam pipe 22 is subjected to pressure reduction by a primary side pressure- reduction temperature-reduction device 3, is subjected to temperature reduction by water being emitted from a spray pipe 8, and is introduced to a secondary side pressure-reduction temperature-reduction device 4. The introduced steam passes through the small hole of a porous plate 6 and hence is subjected to pressure reduction, and then enters a deaeration part 4b. In this case, the replenishment water is deaerated by spraying the replenishment water being introduced from a replenishment pipe 7 into steam being subjected to pressure reduction through the porous plate 6 for mixing.  Then, the mixed body between the steam through the deaeration part 4b and the replenishment water enters a third room 4c and passes through the small hole of the porous plate 6 at a third stage so that it is subjected to pressure reduction and temperature reduction and enters a steam condenser 1. This sort of configuration eliminates the need for providing any special deaeration facility such as a normal deaerator for starting.

Title: Part packaging method
Inventor: TANAKA SUEHIRO
IPC: H05K13/04
Filed: 1986-04-15
Abstract: PURPOSE:To make it possible to package a part onto a carrier member with a high degree of reliability, by measuring the thickness and width of the part when the part is packaged onto the member set on a sliding table by a packaging head. CONSTITUTION:The presence of a part is detected, and the dimensions of the same, that is, the thickness and the width of the same are measured. If the dimensions of the part are equal to preset dimensions of a regular part to be packaged, it is determined that the part taken out by a packaging head is the regular part, and therefore, the part is rotated in a designated arbitrary direction by means of a rotary section to be packaged on a carrier member. If the measured thickness of the part is equal to the thickness of the regular part but the measured width of the same is unequal to the width of the regular part, it is determined that the part taken out by the packaging head is the regular one but the part is absorbed being shifted from the regular direction thereof by 90 deg.. However, if the measured width and length of the part are different from the regular one although the measure thickness of the part is equal to the thickness of the regular one as a result of comparison, it is determined that the part is not the regular one, and therefore, the machine is stopped to prevent the part from being packaged.

Title: Unsaturated logical circuit
Inventor: FUJITA KATSUJI
IPC: H03K19/018
Filed: 1988-04-08
Abstract: PURPOSE:To speed up operation without causing the steady increase of power consumption by composing an output part of first-polarity first and second transistors and a second-polarity third transistor. CONSTITUTION:An output part 30 is equipped with n-p-n transistor 31 and 32, a diode composed of a p-n junction diode, etc., a constant current source 34 and a p-n-p transistor 35. When a signal Vin1 changes from low-level to high-level, a load capacity is charged rapidly with the large collector current of a transistor 32 in an ON state and a terminal voltage Vout of the load capacity 20 rises quickly. On the other hand, when the signal Vin1 changes from high-level to low-level, the load capacity 20 is discharged to an earth through the transistor 35. At the time of the discharge, the load capacity 20 is discharged of a large current into which the current of the constant current source 34 is amplified by the p-n-p transistor 35 and therefore, the terminal voltage Vout of the load capacity falls quickly in the same way as the time of the rise. Thus, the operation can be speeded up without causing the steady increase of power consumption.

Filed: 1978-07-18
Abstract: PURPOSE:To eable the direct operating with IC by providing the PN-junction light emitting diode at the position adjacent to the laser oscillation area in the active layer of the buried double hetero junction semiconductor laser. CONSTITUTION:On a n-type substrate 1 formed are n-type layer 2, p-type active layer 3 and p-type layer 4 in turn. After mesa-etching these layers in the stripeform, n-type layers 5 between which buried is the active layer is formed. Then within the layer 5 formed is a p-type layer 6, on which an ohmic electrode is provided to form a stripeform electrode type buried double junction laser. In this structure, the PN- junction consisted of the layers 5 and 6 emits light by positively biasing a current terminal 13 against another terminal 11. The active layer is pumped through the emitted light. Current is injected into the active layer 3 by positively biasing a current terminal 12 in this state. At this time, the amount of the injected current into the layer 3 for effecting the easer oscillation decreases as the strength of pumping light increases. This enables to decrease the amount of the injected current requiped for oscillating the laser significantly and thus to effect the direct operating with IC.

Abstract: PURPOSE:To obtain a highly reliable laser with high-speed response by a method wherein double grooves that reach to an active layer are formed on the outside of the double channels so as to reduce the high-frequency current flowing in unnecessary part. CONSTITUTION:After a DC-PBH LD structure multi-layer wafer has been produced in a conventional method, 2 grooves 60 and 61 are etched with selective etching liquid of H2SO4 system and HC system from the surface so that the grooves stop at the upper part of an active layer 3. Then, when the etching is performed with a solution of H2SO4:H2O2:H2O=3:1:1, the active layer 3 is etched not only to the bottom section of the grooves 60 and 61 but also to the inside of the channels 51 and 52. Then, an SiO2 film is laminated on the whole surface with thickness of 3,000Angstrom , and an SiO2 film is also laminated in the gaps 70, 71, 72, and 73. The SiO2 film on the stripe region 80 is removed to form a Cr/Au film on the whole surface as a p-side electrode 21, and an n-side electrode 22 is formed with Au-Ge-Ni. The capacity at the gaps 70 and 72 is small so that the high-frequency current is restricted to flow in the channel sections 51 and 52, thereby improving the high-speed response characteristics.
