Filed: 1979-02-16
Abstract: PURPOSE:To realize the high-speed operation by memorizing the product into the ROM for the filter coefficient value of the digital filter and the all value which can be obtained with the data led out of the delay block. CONSTITUTION:The product of the data with the bit length set to L and filter coefficient value hj is memorized in addresses a0-aL-1. In this case,the ROM region of the 2L words is allotted to each hj, and thus the capacity of the NX2L words is necessary in case the filter order number is N. The input signal of line 11 is supplied in series to shift register 13 via serial-parallel converter 12. And each stage of the N steps holds data xn... of L bit, and multiplexer 14 extracts the data of each stasge in sequence to hold them at register 16. And the data gives the address to the region corresponding to ROM17. Thus the specific region corresponding to each coefficient is selected, and the value corresponding to the multiplication result is held at register 18 to be then added the result held at register 19 via adder 21. The added value is then delivered to register 20.

Title: Heat treatment system
Inventor: RICHIYAADO EMU UEEBAA
IPC: F25B19/00
Filed: 1995-02-03
Abstract: PURPOSE: To obtain a heat treatment system for aircraft in which the capacity is enhanced without having any adverse effect on the performance of the aircraft. CONSTITUTION: A heat treatment system uses an expendable liquid which undergoes phase change to a vapor as waste heat is absorbed and also posses a high latent heat of vaporization. The vapor is expelled, carrying with it the waste heat. A vacuum source lowers the vapor pressure to lower the vaporization temperature. In one embodiment, regulated liquid flows into a heat exchanger having a pressure lowered through a vacuum system. Waste heat transmitted to the heat exchanger through a cooling liquid system boils up a liquid at a desired temperature. A flow regulator controls the rate of fluid flow from a pressurized reservoir to the heat exchanger. Cooling effect is attained when the liquid changes from liquid phase to gas phase to absorb heat from the cooling liquid during phase transition.

Title: Stop position controller for motor-driven truck
Inventor: SEKI KIYOTAKA
IPC: G05D1/02
Filed: 1995-02-03
Abstract: PURPOSE: To prevent the usage of an automatic rental safe from being disabled by exactly stopping a motor-driven truck at a target position by changing a correcting operation in the state of calculating traveling time so that the motor-driven truck can be accelerated to low speed and braked later to be stopped after the lapse of traveling time. CONSTITUTION: When both a pair of stop position detectors 41 and 42 perform the correcting operation for applying braking to stop an object 72 to be detected at the detected position for a motor-driven truck 15, an arithmetic control circuit calculates the traveling time from the start of the acceleration of the motor-driven truck 15 to the application of braking. In that calculating state, the motor-driven truck 15, that stops traveling in the state of detecting no object 72 to be detected with either or both a pair of stop position detectors 41 and 42, is stopped by applying braking in the state after the lapse of traveling time after accelerating it until constant-speed traveling at low speed is provided in the direction where the object 72 to be detected is detected by a pair of stop position detectors 41 and 42.  Therefore, the usage of automatic rental safe can be prevented from being disabled.
