Title: Water supply apparatus for multiple dwelling house
Inventor: FUKUHARA YOSHITAKA
IPC: E03B7/07
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To prevent water from being stolen in a multiple dwelling house by incorporating a three-way ball valve in a portion where a water supply pipe branches to each dwelling house of the multiple dwelling house, and suspending the supply of water in every dwelling house. SOLUTION: Three-way ball valves 17, 17a are incorporated in the portions where water supply horizontal pipes 9 branche off from a water supply vertical pipe 8, which are the portions where water supply pipes branche at every dwelling house 4 of a multiple dwelling house 3. For example, in the case of a multiple dwelling house in which one dwelling house is placed in each floor of a three-story building, the three-way ball valve 17 incorporated in a portion where the water supply horizontal pipe 9 of the first and the second floors branches is opened in three ways, and the valve 17a incorporated in the water supply horizontal pipe 9 of the dwelling house 4 at the third floor is opened in two ways to supply water.  In suspending the supply of water to the dwelling house 4 which is a vacant room, the forms of the valves 17, 17a incorporated in portions where the water supply horizontal pipe 9 to the vacant room branches off from the water supply vertical pipe 8 are switched to open in two-way or in one-way, thereby closing ports of the valves 17, 17a communicated with the vacant room. Thus, the supply water can be suspended at every dwelling house 4 so as to surely prevent water from being stolen.

Filed: 1992-06-23
Abstract: PURPOSE:To lower the refractive index of the above material than heretofore by dispersing microholes consisting of vacuum, air or gases, such as nitrogen, in place of superfine particle into a matrix material. CONSTITUTION:The microholes are dispersed into a transparent material to lower the refractive index of the transparent material itself to the lower refractive index. The microholes consist of the vacuum or gases and the size of the microholes is preferably from 10Angstrom to about the wavelength to be used. The transparent material may be any of a high-polymer material, inorg. material and inorg. high-polymer composite material. The refractive index may be provided with a distribution as well. This material is usable also as an optical thin-film material and is usable as an optical bulk material as well. Then, the refractive index of a treated surface layer in, for example, an antireflection treatment is approximate more to the refractive index of the air than heretofore and, therefore, a high antireflection effect is obtd.

Title: Air-fuel ratio control system for internal combustion engine
Inventor: KATO TATSUNORI
IPC: F01N3/32
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To control air-fuel ratio in exhaust gas to a target air-fuel ratio as well as control supply air-fuel ratio of an engine to a target supply air-fuel ratio in a system introducing secondary air in an exhaust system. SOLUTION: An exhaust pipe has an oxygen sensor or air-fuel ratio sensor. When a requirement for feedback control is satisfied, a secondary air introduction amount feedback correction factor SAIR is calculated based on detected air-fuel ratio in exhaust gas after secondary air is introduced. Then, feedback control of secondary air introduction amount is performed so as to make air-fuel mixture in exhaust gas target air-fuel ratio TGINAF. In addition, an actual supply air-fuel ratio SAIRAF of an engine is calculated based on the target air-fuel ratio TGINAF and variation in air-fuel ratio due to introduction of secondary air (hatched portion). Based on the deviation DELAF between a target supply air-fuel ratio TGAF and the supply air-fuel ratio SAIRAF, a learning correction factor KGij for fuel injection volume is renewed.  Correction of fuel injection volume by means of the learning correction factor KGij makes it possible to control the supply air-fuel ratio SAIRAF to the target supply air-fuel ratio TGAF.

Abstract: PURPOSE:To suppress the distortion of a column minimum by controlling the difference of the current value from a movement command value to an electrode rise/fall speed control device, i.e. droop amount, sensing the distortion of column, and by controlling the rise/fall speed. CONSTITUTION:An electrode rise/fall command is given by a memory 7 through a memory 2 at every unit time to move a table 12 or an electrode 16 with a motor 8, and the actual moving amount is measured by an encoder 9 to be stored in a memory 1. A device 3 makes cumulative calculation of the deviation of the memories 1, 2, and a comparator 5 compares it with the allowable value of a memory 4, and if below the allowable value, a device 6 adds the stored data in the device 3 to the data in memory 2, and the result is forwarded to the memory 7. When the allowable value is exceeded, on the other hand, the stored data in the device 3 is forwarded to the memory 7, and next data input to the memory 2 is stopped, and moving command speed for electrode 16 is decreased. Thus the distortion of column 14 is suppressed minimum, and interpolar discharge products are exhausted quickly to lead to stabilization of the processing condition.
