Patent JP-H0320142-A (JP)
Title: Power transmission
Inventor: TERAOKA MASAO
IPC: F16H48/12
Filed: 1989-06-13
Abstract: PURPOSE:To maintain a differential limit between respective turning members as well as to improve the extent of rectilinear stability by letting a connecting means, transmitting input torque to each transmission member, perform intermission of the torque transfer, and providing an energizing means giving clamping force to a friction limiting means even when each clutch is released. CONSTITUTION:In an interval between hub members 51 and 53, there is provided a multiple disk clutch 93 which joins a lot of friction disk set up alternately by means of spline engagement. This multiple disk clutch 93 is always clamped with specified pressing force in a gap with a collar 55 by a disk spring 95. Consequently, it transmits an input torque to each of symmetrical rear wheels. Even if clamping force of multiple disk clutches 57, 59 is weakened or opened free, differential motion between these symmetrical rear wheels is limited by dont of the clamping force of the multiple disk clutch 93, so that these rear wheels will not come to state of free rotation each other. Accordingly, rectilinear stability in a vehicle is thus improvable.

The inner diameter of an opening 6 in the center of a heat exchanger fin 8 is made a little larger than the outer diameter of a pipe 5, that is, the inner diameter should be determined to the optimum value in order to smoothly put the heat exchanger fin 8 around the pipe 5, and to hold it on the outer periphery of a pipe 5. Then a pipe expansion rod 10 is inserted into the pipe 5 from its one open end and is pulled out from the other end. A band of cutting edges 9 of which diameter is larger than the inner diameter of a heat pipe is provided around the pipe expansion rod 10. Both ends of a pipe 5 are sealed by end plates 11 and 12, and the inside of a pipe 5 is vacuumed by sucking the air from a sucking port 13. Then operating fluid is injected inside and the sucking port 13 is closed by sealing. Grooves 14 formed on the inside wall of a pipe 5 by the cutting edges 9 of a pipe expansion rod 10 function as the wick of a heat pipe.

Abstract: PURPOSE:To prevent deformation by baking pot core moldings with and without grooves after stacking them so that end faces of them located at the side of each coil insertion port abut on each other. CONSTITUTION:Having each same outer diameter, pot core moldings 12 and 10 with and without grooves are stacked on a furnace material 14 so that end faces of them located on the side of each coil insertion port abut on each other and then, they are baked.

A character font detection means 1 stratifies density, for example, the number of pixels of a character font by four stages by a signal from a character generator 2 and selects ink layers 5a-5d corresponding to the number of pixels. In other words, a motor 8 is rotated to detect slit parts (12b-12d) at a ribbon position detecting plate 12 with a font sensor 15 and the ink layer (5a-5d) selected is set at a printing position. This enables the selection of the optimum ink layer of the fabric ribbon to print thereby enabling realization of printing of a high quality without drop in density, squeezed character an the like.

Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which the embrittlement degree of two-phase stainless steel is detected by estimating the room-temperature Charpy impact absorbed energy of the stainless steel by using a specific expression. SOLUTION: The Charpy impact absorbed energy of an actual machine is found by using a expression on the basis of measured values which can be obtained by inspecting the actual machine nondestructively, i.e., the hardness HvF of a ferrite phase, the hardness HvA of an austenite phase, the area rate FN of the ferrite phase, the interval FS of the ferrite phase, and the percentage LC of a carbide. In the expression, (g) represents a correction factor, d1, d2, f0, f1, g0, g1, a0, a1, C0, C1 and K0 represent respective constants, and CvR represents a material constant. A drop in the absorbed ebergy means embrittlement, and it can be used as one display method for the embrittlement degree.  In addition, regarding the corresponding absorbed energy CvR of an exfoliation grain boundary face, no correlative one is formed as different form the corresponding absorbed energy CvF of the ferrite phase and the corresponding absorbed energy CvA of the austenite phase, a nondestructive estimation is impossible, and it is expressed as a material constant.

Title: Parallel connected power supply system
Inventor: KATO TSUTOMU
IPC: H02J1/00
Filed: 1991-05-24
Abstract: PURPOSE:To enhance reliability as a power supply by sustaining current supply if current can be fed to a load from a power supply other than an interrupted one. CONSTITUTION:Under a state where stop signals are delivered from two or more DC power supplies 1-4, a parallel redundancy operation control section 14 receives overcurrent detection signals 16-19 from any one of the operating DC power supplies 1-4. At that time, a power ON/OFF control section 15 for the DC power supplies 1-4 delivers power ON/OFF signals 24-27 to the DC power supplies 1-4, respectively. Consequently, the DC power supplies 1-4 stop operation to interrupt power supply to a load. According to the invention, reliability of power supply can be enhanced by sustaining current supply so long as any one of the power supplies 1-4 can feed current to the load.
