Abstract: PROBLEM TO BE SOLVED: To obtain high torque at a low rotational speed and reduce cost and weight without a speed reduction unit by bringing into contact the inner and outer contact surfaces along a point contact, providing a propulsion means on one member, and urging the other member in a rolling orbital motion. SOLUTION: This motive power apparatus is equipped with a stationary member 1 and a movable member 2. The movable member 2 has a cylindrical inner contact surface 20 coming into contact with a cylindrical outer contact surface 21 of the stationary member 1. In the rolling orbital motion, the movable member 2 moves around the outside of the stationary member 1. The movable member 2 retains a cutting member 3 fixed to or formed in a body which is unified with the movable member 2. A solenoid aggregate 5 is excited in succession, and the movable member 2 is urged in a rolling orbital motion around a central part 4 of the stationary member 1. Since the cutting member 3 is a unified part of the movable member 2, the cutting member 3 moves in the same rolling orbital motion. With such a constitution, high torque can be obtained low rotational speeds.

Title: Method for driving electrochromic element
Inventor: ISHIBASHI AKIRA
IPC: G02F1/163
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a driving method capable of simplifying the use of an electrochromic element(ECD) by decreasing the factors to be controlled from outside as well as to expand the voltage range for driving this ECD and to simplify the operation for coloration and color holding. SOLUTION: The color development and color holding of the ECD 1 are executed by constant current via a constant current element. This constant current element is usable by connecting a diode 3 in a reverse direction to the ECD 1. The color development and holding time of the ECD 1 are greatly prolonged by making up the self-discharge current of the ECD 1 from a diode 3 connected in a reverse direction. The terminals of the ECD 1 are released to cause self-discharge at prescribed intervals, by which the deterioration of the ECD 1 by overdischarging is prevented when the current flowing from the constant current element is larger than the self-discharge current of the ECD 1.  Further, the terminals of the ECD 1 are released to cause the self- discharge before the connection to the constant current element after the color development, by which the holding of the color is made possible while the voltage of the ECD 1 is suppressed low.

IPC: G06F12/10
Filed: 1987-09-07
Abstract: PURPOSE:To prevent the performance of a device from being reduced due to a mishit without increasing the number of sets in a class, by temporarily storing address converting information substituted for a TLB in a converting information stack and writing the information in the TLB when it is necessary. CONSTITUTION:At the time of detecting a TLB mishit by a control circuit at the time of retrieving the TLB, the converting information stack 8 is retrieved. At the time of the retrieval, a stack address forming circuit 11 successively forms addresses for reading out all entries 9 of the stack 8 by using an increment 12 and detects a stack hit. At the time of detecting a stack mishit, an address conversion request is generated, and if converting information outputted by the set substituting operation of the TLB 2 exists, the information is written in the stack 8. Even when set substitution in a specific class 3 of the TLB 3 is frequently generated, the set is rewritten from the stack 8 to the TLB 2 if necessary, so that the system performance can be prevented from being dropped due to the mishit.

Title: Multifunctional peripheral device and recording medium
Inventor: MINAMIZAWA FUMIHIRO
IPC: H04N1/32
Filed: 1996-08-26
Abstract: PROBLEM TO BE SOLVED: To avoid a function stop due to the lack of memory capacity by inhibiting the reception of data related to a specific function out of received data by a transmitting/receiving means and plural functions when a remaining capacity judging means judges that the remaining capacity of a storage means is less than a prescribed value. SOLUTION: A CPU 31 in an MFD 2 judges the existence of receiving data from a personal computer 1, and when the data exist, judges whether a transmission mode through a cable 51 is a multiplex communication mode or not. In the case of the multiplex communication mode, the CPU 31 judges whether the remaining capacity of a RAM 33 is less than a prescribed value or not. When the capacity is less than the prescribed value and the receiving data are printing data, the CPU 31 judges whether a flag stored in an EEPROM 34 is '0' or not, i.e., untransmission or not. When data are not transmitted yet, the CPU 31 transmits a command for inhibiting the reception of printing data to the computer 1 through the cable 51, so that the transmission of printing data to the MFD 2 is stopped.

Title: Treatment of waste
Inventor: GOTO TATSUO
IPC: B09B1/00
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a method for treating waste in which waste is efficiently treated and also effective utilization is enabled. SOLUTION: Fuel is supplied from a fuel tank 2 to a combustion furnace 1 and combustion is started. Waste is charged into a dry distillation furnace 6. When heat H of combustion in the combustion furnace 1 is transmitted to the dry distillation furnace 6, thermal decomposition of carbon compounds such as various plastics, wood and paper contained in waste is started. Thereby, gas G plentifully containing combustible gas is generated. This gas G is introduced into the combustion furnace 1 from a discharge pipe 7. Combustible gas contained in gas G is burned in the combustion furnace 1 and therefore even if the feed amount of fuel from the fuel tank 2 to the combustion furnace 1 is reduced, equal heat H of combustion is obtained. Further, carbonaceous substance remains as dry distilled material in the dry distillation furance 6.  The carbonaceous substance is deposited and conserved in the ground.
