Abstract: PROBLEM TO BE SOLVED: To operate a mill stably by injecting water to a crushed raw material on the respective rotary tables of roller mills for supplying coal to a boiler and shifting the timing for starting or stopping water injection of at least one roller mill from that of other roller mills. SOLUTION: A crushed raw material 4 is dropped on a rotary table 2 through a raw material supply pipe 5 and compression-crushed by a crushing roller 1, large particles are separated by a rotary sorter 7, and only powdered coal is sent to a powdered coal burner. In this process, in the catching part of the crushing roller 1, a water spray flow 14 is sprayed from a nozzle 13 on a raw material powder layer 3 on a rotary table 2, to control the self-excited vibration of roller mills. When the roller mills change the amount of supplied coal simultaneously, the time delay of the start or stop of water injection is set up for at least one roller mill to other roller mills corresponding to the load changing speed of a boiler.

Title: Brake valve
Inventor: WAKABAYASHI TSUGUO
IPC: B60T15/04
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent a brake from being suddenly operated to cause a suddenly braked state when a brake pedal is depressed at a general speed by providing a diaphragm in a reservoir port. SOLUTION: When a brake pedal is depressed, an input piston 3 moves a valve spool 4 through a compression spring 9. The pressure oil from a pump to a tank is gradually reduced, and the pressure oil from a pump to a brake cylinder is gradually increased to operate the brake. Since a reservoir port R has a diaphragm 6, a resistance is imparted to the pressure oil returned from reservoir chamber 5 to a tank, and a fluid reaction according to the depressing speed is imparted to the brake pedal. Consequently, when the brake pedal is depressed at a general speed, the brake is laid in general braked state, and a suddenly braked state is not formed.

Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To realize the sure air vent and stable pouring of hot water by intermittently and forcibly discharging the air generated in a hot water storage tank when water is boiled by an opening/closing means. SOLUTION: An opening/closing means 8 is opened according to the ON/OFF action of a heat source 5 or the air volume at each prescribed interval. The interval or frequency of the opening/closing time can be appropriately changed. A solenoid valve 8 is intermittently and forcibly opened by commanding such conditions from a controller 9 of the solenoid valve. When the solenoid valve 8 is opened, air together with hot water is discharged from an open end to a water discharge port 7 through a pipe 6. Scales such as calcium ion adhered to the pipe wall are frequently discharged together with air and hot water, and no scales are fixed to the pipe wall, and hot water of excellent quality is provided.  Because hot water which is intermittently discharged from the pipe 6 is used as the sealing water of the water discharge port 7, no bad smell is generated even when water is not used for a long time, and when a faucet 11 is opened, hot water can be smoothly supplied without including air.

Title: Demodulation method for demodulation of, especially, differential phase-shifted keying signal
Inventor: ISURAERU BAA DEIBUITSUDO
IPC: H04L27/22
Filed: 1992-07-06
Abstract: PURPOSE: To solve such a problem that the number of vibrations becomes uncertain at the time of making multiphase differential detection by using a plurality of phases. CONSTITUTION: Relating to a method and device for demodulating modulated signals having carrier components and data components, the modulated signals are divided into at least two parts and one part is delayed against the other part. The two parts are multiplier-coupled with each other and, at the same time, linearly combined together and generate the combinational output corresponding to a carrier component frequency and the function of an independent data component. In addition, the non-delayed part is coupled with the delayed part by means of a multiport coupler 16 and the two parts are relatively phase- shifted from each other and generate a plurality of phase-shifted signals.  The phase-shifted signals are linearly combined so that the data component may not be affected by the variation or fluctuation of the frequency or phase of the carrier component in the function of the combined output.

Abstract: PROBLEM TO BE SOLVED: To obtain an enough antireflection effect and a shielding effect against electromagnetic waves by constituting the first high refractive index material layer from the base body side of an antireflection laminated body of two layers different in refractive index. SOLUTION: This antireflection laminated body 1 is produced by successively forming layers of an antireflection film 3 on a base body 2. The antireflection film 3 consists essentially of ceramic thin film layers of a high refractive index layer 4 and a medium refractive index layer 5 of a same material, a medium refractive index layer 7 of another high refractive index material, and low refractive index layers 6, 8. The layers 4, 5 may be a medium refractive index layer and a high refractive index layer, respectively. At least one layer of these layers is a ceramic thin film layer having electric conductivity. Thereby, electric conductivity can be added which is not added to a conventional antireflection laminated body consisting of only dielectric materials.  Further, since the number of optical film layers is larger by one than the number of layers as materials, the degree of freedom in designing the optical film thickness is increased.

Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To make possible reproduction with a reproducing beam of an optimum wavelength according to recording density by detecting the recording density and revising the reproducing beam wavelength based on the detected recording density. SOLUTION: A disk servo means 4 inputs a reproducing pilot signal from a pilot signal separation means 3, and phase compares a reference signal with the reproducing pilot signal to control a rotational phase of a disk motor 5. After arriving at a fixed speed rotation state, a linear speed detection means 6 counts a period of a rotational detection signal obtained from the disk motor 5 to discriminate the recording linear speed from a rotational speed in an initial position. A reproducing beam revision means 7 based on the discriminated output selectively drives an answering semiconductor laser B1 or B2. Thus, the optimum reproducing beam wavelength is selected.

Filed: 1982-11-16
Abstract: PURPOSE:To attain suitable data extraction by generating a forecasting signal to a position constant in a lead or lag direction from a normal position of a changing point of a modulating signal to absorb jitter 5. CONSTITUTION:Mutual intervals ''1'', ''1.5'', ''2'' of changing points of a modulating signal are set to 22, 33, 44 bits. When the mutual interval of a pulse signal is spread and a counted value (x) of a counter 2 is 1<=x<5, a counted value (y) of a 11-notation counter 6 is zero, a logical ''1'' signal is generated from an AND circuit 3 and it becomes a forecasting pulse signal and a reset signal. In this case, the mutual interval of the forecasting signal is made shorter than the mutual interval of the pulse signal. Further, the generating position of the forecasting signal is located to one bit in the delay direction from the normal position of the pulse signal. Then, a data signal is extracted by a phase detecting circuit 9 by the mutual interval of the forecasting pulse signal and a clock signal from a binary counter 8.
