IPC: H04B14/04
Filed: 1986-09-05
Abstract: PURPOSE:To decide the operation of a decoding section to be normal by storing a digital sine wave signal in a short time in a memory, repeating this operation to input the result to an encoding section, and inputting the outputted encoded code to a decoding section to make the difference between the level of an output signal and the level of an input sine wave signal constant.

Signals that passed the decoding section 3 are fetched to the circuit 5, and the level is measured. Then, the level is compared with the sine wave signal level accumulated in the circuit. If the difference is within a fixed limit, the operation of both the encoder and decoder is judged as normal, and when out of the limits, an alarm signal 17 is inputted to the package interface 9 and displayed in an LED etc. Thus, it is made possible to execute operation confirming test in own unit.

Title: Heat exchanger for recovering heat
Inventor: FUJII MASAO
IPC: F28D15/02
Filed: 1982-11-25
Abstract: PURPOSE:To vary a heat-exchanging area for the second heat exchanger in response to variation in the quantity of a hot gas and moderate temperature variation in a container even when variations in load and the quantity of the hot gas become large, by charging a non-condensible gas into a heat exchanger for recovering heat. CONSTITUTION:When the quantity of the hot gas is increased, the pressure in a hermetically sealed container 1 is raised by a vapor generated, whereby a non- condensible gas is pushed up to an upper part, and the contact area between the second heat exchanger 4 and the vapor is enlarged, so that the quantity of heat processed by the heat exchanger 4 is enlarged, and heat exchange is accelerated. Acordingly, the temperature (pressure) in the container 1 is lowered to approach a steady state. When the quantity of the hot gas is reduced, the pressure in the container 1 is lowered because the quantity of the vapor generated is small, the occupating factor of the non-condensible gas 5 is increased, and the contact area between the heat exchanger 4 and the vapor generated is reduced, so that the quantity of heat processed by the heat exchanger 4 is reduced, and heat exchange is restricted.

Title: I/o module
Inventor: NAKAUCHI NORIO
IPC: G06F13/12
Filed: 1987-08-24
Abstract: PURPOSE:To improve the general usefulness to the bit constitution of an external interface data bus by storing a part of data supplied from a CPU in a temporary register capable of inputting/outputting data corresponding to the number of different bits when the bit constitution of a data register in an I/O module and that of a data bus connected to the module are different from each other, in order to set the data in all the bits at a time. CONSTITUTION:In reading sixteen bits of data from the data register DR 1, the CPU reads the high-order byte directly from the register DR 1 in a first cycle, stores the low-order byte temporarily in the temporary register TR, then read the low-order byte from the register TR in the subsequent cycle. When sixteen bits of data is written in the data register DR 1, the CPU makes access to the temporary register TR for writing the low-order byte in the first cycle, and in the subsequent cycle, makes access to the data register DR 1 for writing the high-order byte. As a result, the general usefulness to the bit constitution of a data bus for interfacing with the external can be improved.

IPC: F02D29/02
Filed: 1988-08-23
Abstract: PURPOSE:To increase the extent of engine output easily as well as to make improvements in operation efficiency by storing a mode higher in output than the basic mode, and when the engine output is cut off, suspending this cutoff as long as the specified time and thereby altering the mode. CONSTITUTION:Each of basic modes H, S, L cut of a high output part is set to an engine output full performance curve M in a tractive force-velocity diagram of an engine. In addition, a specified factor is multiplied to latch tractive force at a time when a shoe slip factor has come to the specified value, and thereby control modes H', S', L' are set up as an output cutoff value. Moreover the engine output is cut off till the shoe slip factor comes to the specified value. In this case, a mode higher in output than these basic modes H, S, L is stored in memory, and when the engine output is cut off, a cutoff of the engine output is suspended as long as the specified time, thus a mode alteration takes place.

Abstract: PURPOSE:To obtain the titled oscillation preventing apparatus insensitive to the influence of heat and easily producible at a low cost, by placing an oscillation preventing jig above a seed crystal holder and supporting the oscillation preventing jig via a gas ejected through a nozzle of a holding jig placed in a crystallization chamber. CONSTITUTION:A cap-shaped oscillation preventing jig 7 having wedge cross-sections at both sides is placed at the center of a crystallization chamber A and a wire 3 is inserted through the center of the oscillation preventing jig 7 in a freely rotatable and vertically movable manner. A holding jig 8 having tapered opposite face having an angle equal to the side angle of the wedge-shaped oscillation preventing jig 7 is attached to the inner wall surrounding the oscillation preventing jig 7. Plural gas ejection nozzles 9 are bored to the chamber-side wall of the holding jig 8 and the oscillation preventing jig 7 is supported by the gas ejected from the gas-ejection nozzle 9. When the single crystal 5 is forced to shift along a radial direction, the gap between the oscillation preventing jig 7 and the holding jig 8 is narrowed at the direction of displacement to increase the pressure of the gas and the oscillation preventing jig 7 is pushed back toward the center. Accordingly the oscillation of the single crystal 5 can be prevented.
