IPC: F16D66/00
Filed: 1989-06-05
Abstract: PURPOSE:To have a braking force constant relative to a constant operating force at all times by sensing the temp. change on the friction material surface of a brake body, and correcting the pressure of a working fluid supplied to the brake body according to the change in the friction factor of the friction material. CONSTITUTION:The friction material surface temp. of a brake body 18 is sensed by a temp. sensor 26 and sent to a control means 28, which stores in memory the relation of the preset surface temp. of the friction material to the supplied air pressure. When the surface temp. rises, the friction factor lessens, and the control means 28 opens a pressure boosting valve 32 to boost the air pressure in an air tank 30 so as to hold constant the braking force relative to the brake pedal 14 stamping force. With sink of the surface temp. the friction factor increases, and accordingly a decompressing valve 34 is opened to sink the air pressure in the air tank 30. When the brake pedal 14 is stamped during decompressing motion, a signal Sp is sent to a CPU, which gives a signal to stop the decompressing motion to the decompressing valve 34 so that the braking motion is not hindered.

Abstract: PURPOSE:To facilitate feed water control in relation to contract quantity by estimating final quantity consumed at optional time on the basis of the time sequantial tendency of the quantity consumed in the past, and issuing an alarm when it is decided that the consumed quantity will exceed the contract quantity before it reaches an alarm set value in the water reception and the water distribution of water supply from prefectural water-supply, etc. CONSTITUTION:An arithmetic circuit 4 integrates the flow rate signal of a flow meter 2 fetched from an interface circuit 3. A memory 6 stores the time sequantial pattern of a day of instantaneous quantity consumed and the parameters of the contract quantity and the alarm set value, etc. An arithmetic part 7 calculates the final consumed quantity estimated to be consumed in that day on the basis of the quantity consumed calculated by the integration circuit 4 and the parameters stored in the memory 6. A deciding part 8 compares the arithmetic result of the arithmetic part 7 with the contract quantity stored in the memory 6, and the consumed quantity with the alarm set value respectively, and decides whether the alarm is to be issued or not. When the deciding part 8 decides the alarm to be issued, an alarm generation circuit 9 outputs an alarm signal to the outside.

IPC: F21V3/04
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To reduce the number of insects attracted to a light source by adding a filter function for preventing the transmission of ultraviolet ray and visual light having specified wavelength areas which prevent the visual confirmation in relation to the light source by insects to a glove. SOLUTION: A white fluorescent lamp shown by FPL 13EX-L is used as a light source 2, and a transparent glove made of an acrylic styrene resin having an ultraviolet ray absorber kneaded thereto is used as a glove 3. As the ultraviolet ray absorber to be kneaded in molding, a salicylate base compound is used, and the wavelength to be absorbed is changed by variously changing the structure. Wavelengths not more than 360 nm where insects are most attracted are preferably cut, whereby the number of insects attracted to the light source can be reduced, and the reduction in commercial value can be also prevented. The transmission of ultraviolet ray and near ultraviolet ray areas of wavelengths not more than 400 nm is preferably inhibited.

Title: Ink tank unit
Inventor: TAJIMA HIRONORI
IPC: B41J2/175
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To increase the quantity of ink to be contained in an ink tank unit while enhancing the using efficiency of ink by providing a curved face part for preventing deformation of an ink holder at the time of inserting an ink holder at the inner ridge part of a resilient ink holder containing part. SOLUTION: Curved faces are provided at four corners 210 in a negative pressure generating member containing part 203. The curved face structure prevents the ridge part of an ink absorber 205 from being warped or distorted due to friction and the ink absorber 205 comes into uniform pressure contact at four corners so that ink is not concentrated at a locally deformed part. Since possibility of forming an ink channel can be lowered at the ink concentrating part, ink distribution is stabilized and ink can be collected only in the vicinity of an ink supply opening 209 more reliably. Furthermore, wettability is lowered because the ink absorber 205 is not wetted with ink in the vicinity of an opening 208 communicating with the atmosphere.

Title: Subscriber circuit control system
Inventor: ONO CHIYUUKICHI
IPC: H04Q11/04
Filed: 1984-07-09
Abstract: PURPOSE:To reduce the number of bits of a subscriber circuit control signal and to obtain an inexpensive subscriber circuit control system by corresponding the subscriber circuit control signal to a state transition pattern of the said circuit without corresponding to the control point of the said circuit. CONSTITUTION:The correspondence between the control point in the subscriber circuit and the state transition pattern is as shown in figure. The control circuit includes a means transmitting the subscriber circuit control signal applying binary coding to the state transition pattern taken by the controller to the subscriber circuit to a subscriber circuit control memory 2 via a control line 1, and the subscriber circuits 4o, 4l and 4m include a means receiving a control signal and expanding it into another control signal corresponding to the control point. Control signal reception circuits 5o, 5l and 5m store the control signal into a register 8. The said signal is a binary coding of the pattern. The said signal is moved to an expansion circuit 9 to expand the said signal to a signal corresponding to the control point in the subscriber circuit. Thus, it is not necessary for a format in a control highway 3 to take three-multiple frame constitution and one channel/8-bit is enough for the expansion.
