Title: Brake fluid pressure control device
Inventor: FUKAZAWA TSUKASA
IPC: B60T15/36
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent an unreasonable increase in a pedal stroke when an external pressure source fails in a brake fluid pressure control device capable of simulating the pedal stroke at the time of performing fluid pressure control with the external pressure source as a fluid pressure source. SOLUTION: A first fluid pressure chamber 26 and a second fluid pressure chamber 28 of a master cylinder 16 are connected to wheel cylinders 52, 54 through master cutoff valves 44, 46, and a third fluid chamber 30 is connected to a reservoir tank 38 through a reservoir cutoff valve 58. Normally, when brake operation is performed, the master cutoff valves 44, 46 are closed, while the reservoir cutoff valve 58 is opened, and in this state, brake fluid pressure is controlled with an external pressure source 60 as a fluid pressure source. When the external pressure source 60 fails, the master cutoff valves 44, 46 are opened to communicate the master cylinder 16 with the wheel cylinders 52, 54, and the reservoir cutoff valve 58 is closed.

Title: Heating control device for hot water supplying device
Inventor: OKAMOTO HIDEO
IPC: F24H1/10
Filed: 1988-12-14
Abstract: PURPOSE:To delay the heating if the water temperature in the heat exchanger is high enough by determining the time interval between the moment when the water passes through the heat exchanger to the start of heating based on the temperature of water leaving the heat exchanger. CONSTITUTION:When the water flow is detected through a pulse signal from a water rate sensor 35, an ignition control section 41 computes the time interval up to the start of burning, i.e. the ignition delay time (t) based on the temperature Tex, detected by the use of a heat exchange thermistor 38, of water (hot water) leaving the heat exchanger 32 by t=(Tex-Tbase).h where Tbase is the baseline temperature to determine the delay time (t), and (h) is the coefficient. It then causes the ignition while the shutoff solenoid valve 21 and the main solenoid valve 22 are held opened when afore-said delay time (t) has elapsed. Therefore, if the heat exchanger 32 is being heated by the residual heat of the burning apparatus 10 such as burner plate 11, etc., a redundant heating will not be performed.

Title: Polybutylene terephthalate multi-layer blow molded product
Inventor: ITO HARUYASU
IPC: B32B27/36
Filed: 1989-12-05
Abstract: PURPOSE:To obtain a large-sized blow molded product without having surface roughening, by specifying a thickness of one layer of a straight-chainlike a polybutylene terephthalate (PBT) resin layer. CONSTITUTION:A branch PBT resin layer whose melt index measured under a condition where a temperature is 235 deg.C and load is 2,160g is 2.0 or less and a straight-chainlike PBT resin layer are laminated and a thickness of one layer of the striaght-chainlike PBT resin layer falls within a range of 2-50% of the total thickness of a molded product. In the case where a ratio of the total thickness of the straight-chainlike PBT to the total thickness is excessive, molten tension of a parison is weak, drawdown is generated and moldability is worsend remarkably. Then when the ratio is too little, prevention effect of surface roughening of the surface of a molded product becomes insufficient. The blow molded product is obtained by a method wherein the branch PBT resin and the straight-chainlike PBT resin are melted, coextruded by making them into a parison so that the straight-chainlike PBT resin layer becomes the outermost layer and/or the innermost layer and the same is molded with a blow molding method.

Title: Manufacture of combination of ceramic member and metal member
Inventor: OKINAKA MANABU
IPC: B23P19/02
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To facilitate manufacture, and to prevent the evolution of flaws on the inner boundary surface of a recessed part by reducing a press-in load. SOLUTION: The outer boundary surface of a burned ceramic member is polished by centerless polishing to remove a land. Barrel polishing is then applied to the ceramic member. After the process, the ceramic member is pressed in the recessed part of a metal member from one end side having a chamfering part. In pressing-in, the intersected ridge line site formed of the chamfering part and the outer boundary surface is rounded up owing to the barrel polishing. The result decreases a press-in load and flaws no inner surface of the recessed part.

Title: Hydraulic servo valve
Inventor: URATA EIZO
IPC: F15B13/043
Filed: 1990-11-22
Abstract: PURPOSE:To improve operation efficiency of a servo valve by setting a distance between a spool surface and a sleeve inner peripheral surface at a portion near a center compared to a stepped part narrower than a distance between the spool surface and the sleeve inner peripheral surface at a portion near an end of the spool compared to the stepped part. CONSTITUTION:A stepped part 34 is formed on a portion a little near a center of a spool compared to a static pressure bearing 15R. A distance hi between a surface 36s-1 of a spool 34 and an inner peripheral surface 2I of a sleeve 2 at a portion near the center compared to the stepped part 34 is set narrower than a distance code ho between a surface 36s-2 of the spool 34 and the inner peripheral surface 2I of the sleeve 2 at a portion near an end 33 of the spool compared to the stepped part 34. Since the distance hi is set narrower than the distance ho, a flow Qt is strongly throttled bringing about hardness to flow. On the other hand, a flow Qb is, since the distance ho is comparatively large, smoothly flows without resistance.

Filed: 1987-12-14
Abstract: PURPOSE:To protect an insulator from breakdown due to heating, by laying a power transmission line in a conduit buried in the ground between manholes then supplying cooling fluid through the conduit from one manhole toward another manhole. CONSTITUTION:Upon pressure feed of cooling fluid such as cooling water from a pump 13 through a supply pipe 11 into a hollow box 4 while power is being fed to a power transmission cable 8, the cooling fluid flows from the hollow box 4 through respective cable arranging holes 7 of a buried pipe 3 into another hollow box 5.

Title: Reaping harvester
Inventor: KAWASE MUNEYUKI
IPC: A01B63/10
Filed: 1989-12-06
Abstract: PURPOSE:To make a reaping part suitably following to standing culm by forming a construction operating a transferring means for the detection of positional discrepancy in a position-detecting means and operating orienting means for exceeding set times of operation with the transferring means in the same direction within a set timing. CONSTITUTION:An automatic mode is detected by a controller H according to the information from a selecting switch S1 and, for instance, in a case of detected value of a right-side position sensor S2A exceeding yield value, an electric motor 20 is driven to transfer the reaping part to left with sliding as position of the reaping part is exceeded to the right of standing culm. On the other hand, in a case when the frequency of detected values exceeding a threshold value exceeds a set frequency within a set timing, an electromagnetic valve 34 is driven to orient car body to left and the reaping part is controlled to a suitable set position for standing the culm to be reaped. The same treatment is performed also in a case of a right-side position sensor S2B. In a case when both detected values are below a threshold value, the reaping part is decided as in a suitable position and driving of both of the transferring means and the orienting means are stopped.

Title: Roller conveyor
Inventor: MURAYAMA TAKEMI
IPC: B65G13/11
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To easily replace a roller when it is damaged and to easily clean the bottom side of a roller by making an open groove in a frame for a bearing of a tip of one end of the shaft and by easily removably mounting the other end of the shaft on the frame. SOLUTION: One end 22 and the other end 23 of a roller 21 are mounted on a frame 31 and a frame 32 via a shaft 25, respectively. A part of the frame 31 where the shaft 25 of one end 22 of the roller 21 is positioned is cut out and an open groove 34 is made there. The tip of the shaft 25 of the other end 23 is passed through a fixing hole for the shaft. The cross sectional shape of the shaft 25 is a partially cut-out circle and the fixing hole has a similar shape. Therefore even if the roller 21 is rotated, the shaft 25 whose tip is fixed by the fixing hole for the shaft is not rotated and remains fixed. But the roller 21 has bearings in both ends and thus can be rotated even if the shaft 25 is fixed. The roller 21 is replaced by lifting up the end 22 of the roller 21 from the open groove and removing the shaft 25 from the fixing hole for the shaft of the frame 31.
