Abstract: PURPOSE:To decrease the length of a dielectric plate further in the direction of waveguide axis and to obtain the excellent matching of input and output impedances by providing a hole perpendicularly to a plate face in the vicinity of the end of the dielectric plate. CONSTITUTION:A thick dielectric plate 2 is inserted so as to be in contact with the diameter of a circular waveguide 1. Holes 4a, 4b are provided in the vicinity of end faces 3a, 3b of the plate 2 thereby preventing discontinuous capacitance at the end faces 3a, 3b near the waveguide axis in the circular TE11 mode having an electric field component En perpendicular to the plate 2.

Title: Superconducting heat pump
Inventor: NINOMIYA KAZUKI
IPC: F25B23/00
Filed: 1987-12-29
Abstract: PURPOSE:To provide a heat pump which does not require a high pressure by employing a superconductive substance as cooling medium which assumes the superconducting state on the high temperature side and the normal conducting state on the low temperature side for the purpose of performing the heat pump action. CONSTITUTION:Where the magnetic field is set such that there exists a superconductive state in the low magnetic field on the high temperature side, the superconductive substance 1 moves to the low temperature side as the belt 4 is driven, where it loses the superconducting state because of the high magnetic field on the low temperature side to become a normal conductive substance. Since it absorbs heat from the low temperature side in this process, the temperature on the low temperature side is reduced. The superconductive substance 1 moves on to the high temperature side as the belt 4 continues to be driven, where it regains the superconducting state as the high magnetic field is lost on the high temperature side. Since it releases heat in this process, the temperature on the high temperature side is increased. The heat pump action is performed this way. Further, by modulating the values of the low and high magnetic fields, the heat pump can yield a set temperature differential.

Title: Automatic speed change method for running vehicle
Inventor: KUSAKA KOHEI
IPC: F16H59/22
Filed: 1989-12-26
Abstract: PURPOSE:To eliminate unnecessary deceleration so as to contrive improvement of durability by heightening a speed change point to increase an engine speed and increasing a flow rate of cooling oil fed to a retarder, when it is actuated for a preset time or more with an accelerator turned off. CONSTITUTION:A speed changer controller 60, in which a speed changer 16 is automatically speed-changed between predetermined speed shifts in accordance with operation of a shift lever 64 while performing a retarder mode speed change action control for heightening a speed change point when a preset time by a timer 63 elapsed after an action signal of a retarder 61 is input with an accelerator 51 turned off, sufficiently cools the retarder by increasing a speed of an engine 10 to increase a flow amount of cooling oil fed to the retarder 61. In this way, unnecessary deceleration is eliminated without heightening a speed change point even when the accelerator is turned off at the top of a hill and in the inlet of a bad road or the like because a retarder mode is not obtained only by turning off the accelerator. Thus improvement of durability of the speed changer can be contrived.

IPC: G06F12/16
Filed: 1988-12-29
Abstract: PURPOSE:To carry on a processing when intermittent fault occurs to a memory by making a parity check on a program when a program fetch signal indicating that a program is being read is present and making a parity check on data when the program fetch signal is absent. CONSTITUTION:Parity data from a parity check part 41 is classified by a parity error in program reading operation and a parity error in data reading operation in response to the program fetching signal from an arithmetic processing circuit 1. Then when the program fetching signal indicating that the program is being read is present, the parity of the program is checked and when not, the parity of data other than the program is checked. Consequently, even if a parity error occurs, the processing is retried and carried on even in the case of the intermittent fault occurrence of the memory.
