Title: Gas burning tap-controlled water heater
Inventor: NAKAMURA HISASHI
IPC: F24H1/10
Filed: 1985-07-19
Abstract: PURPOSE:To bring down the lower limit burning rate as close to the rate of a zero (0) gauge burner as possible despite a large maximum burning rate and to reduce damages to the solenoid valve, by providing a burner whose calorific value is controlled by modulating the gas flow rate and a burner whose calorific value is controlled by modulating the on-off time ratio of the burner. CONSTITUTION:The water heater main body (a) has two burners 2, 3 for a single heat exchanger 1, and its gas piping 13 is divided into gas piping 13a and 13b. By maintaining at constant the opening of the proportional control valves 16, 17 while repeating opening and closing of the solenoid valves 14, 15 as the cyclic period of opening and closing and the ratio of the opening time to closing time are modulated, a calorific value can be changed in a range from a calorific value at which a continuous burning is performed to a calorific value when the valve closure time is made extremely short, which calorific value is close to zero (0).

Title: Japanese word processing system
Inventor: JINGU YOKO
IPC: G06F17/21
Filed: 1989-06-23
Abstract: PURPOSE:To reduce the hardware scale by compressing the code space which is treated in a code conversion process. CONSTITUTION:A code 100 is provided to converts two areas G0 and G1 separate from each other in a 2-byte code space decided by JIS into the areas which are artificially adjacent to each other. These converted areas are compressed by a compression processor 101. Thus two separate areas G0 and G1 decided by JIS are turned into the areas adjacent to each other and compressed. As a result, all spaces 64K characters of 2-byte codes are not required and the necessary 16K characters or a space compressed down to the value approximate to the 16K characters suffices for execution of a due process. Thus a code conversion table space is reduced and therefore the hardware scale is also reduced.

Title: Trouble foreknowing method for pump equipment
Inventor: UMEZAWA SOHEI
IPC: F04B51/00
Filed: 1988-06-29
Abstract: PURPOSE:To foreknow a trouble in a pump in whatever operational point it may be placed by comparing a measured vibration value with a preset vibration value previously set corresponding to a measured differential pressure. CONSTITUTION:A normal pump is used, and two or more differential pressure values in a vent part 11 are measured by a differential pressure detecting part 4, while a normal vibration value corresponding to this differential pressure value is measured by a vibration sensor 5. The normal vibration value serves as the preset vibration value, and the preset data, based on the differential pressure value and the vibration value when a pump is normal, is input to a computer. A vibration value of his preset data is compared with a vibration value measured in normal operation thereafter. When the measured value is larger than the preset value, a signal of foreknowing a trouble is generated.
