Title: Device for mixing hot and cold water
Inventor: NAGAOKA YUKIO
IPC: F16K11/07
Filed: 1989-10-20
Abstract: PURPOSE:To integrate the functions of a pressure-regulating valve and a temperature- controlling valve in one device and promote compactness of the device by providing a means for producing a variable control force which gives an actuating force to a valve shaft and by providing a connection hole in each of variable restrictors, forming variable openings proportionate to flow rates, provided respectively between a mixing part and each of a valve for hot water and a valve for cold water. CONSTITUTION:When current passed through a coil 21 from a control circuit 18 is increased, a downward force acting on the iron core 20 is intensified and presses a valve shaft 8 downward. This results in closure on the side of cold water and opening on the side of hot water and, through changes in the outlet pressure at a hot-water valve 4 and at a cold water valve 6, an automatic pressure-regulating valve 3 assumes a balance; as a result, the temperature of the hot-cold water mixture rises. When current passed through the coil 21 is decreased, the downward force acting on the iron core 20 is weakened and allows the force of a main spring 24 to move the valve shaft 8 upward, causing opening on the side of cold water and closure on the side of hot water; as a result, the temperature of the hot-cold water mixture falls. Thus by changing the current passed through the coil 21 the balancing point of the automatic pressure-regulating valve 3 can be shifted. A thermistor 15 detects the temperature of the hot-cold water mixture, which the control circuit 18 processes and controls the current passed through the coil 21. The automatic pressure-regulating valve 3 keeps at a balancing point in the variable control force-producing means 19.

Filed: 1991-10-23
Abstract: PURPOSE:To improve the efficiency of various processing, transmission, and storage by the sufficient compression of character string data as to the LZW compressive encoding system and decoding system for various data. CONSTITUTION:A dictionary registering means 1 decodes an input character string divisionally as mutually different partial character strings and registers the correspondence between those partial character strings and codes in a dictionary. An encoding output means 2, on the other hand, selects the partial character string with maximum length which match the input character string among the partial character strings in the dictionary and reads out the code corresponding to the selected partial character string. A length comparing means 2a compares the length of the selected partial character string with a specific value and when the former is shorter than the latter, a 1st output means 2b represents the read code by using the number of bits required to encode the character string having the specific length and outputs it together with an additional identification bit consisting of specific contents. When the former is longer than the latter, on the other hand, a 2nd output means 2c adds an identification bit consisting of contents different from the specific contents to the read code and outputs them as the code of the input character string.

Abstract: PURPOSE:To enable the highly accurate detection of a gap between a mask and a wafer with low-priced structure by providing a squarer for squaring the photoelectric output signal of a detector, and a low-pass filter for extracting only the basic wave from the output of the squarer. CONSTITUTION:When a monochromatic and coherent light such as He-Ne laser is incident on a mask 10 with diffraction grating, two interference waves are generated by diffraction, and the amplitude of the composite wave is changed by a gap between the mask 10 and a wafer 20. However, when the gap between the mask 10 and the wafer 20 is vibrated minutely by a high frequency vibrator such as a piezoelectric element either from the mask 10 side or from the wafer 20 side and the quantity of light detected by a detector 7 is squared (8) and further let pass a low pass filter 9, only the signal of an envelope, that is to be the basic wave, can be extracted. The change by the gap can be thereby detected with low-priced structure compared to the case of dealing with the amplitude of the composite wave.

Title: System for locating troubled point
Inventor: CHIHARA ISAO
IPC: G01R31/08
Filed: 1985-12-09
Abstract: PURPOSE:To attain cost reduction by eliminating an accessory circuit such as a synchronous signal transmitting/receiving circuit by dispensing with simultaneity, by performing the locating operation of a trouble point only by magnitude without using the phase difference between terminal data. CONSTITUTION:The position of a trouble point is calculated on the basis of voltage quantities VA, VB and current quantities IA, IB measured in terminal apparatuses A1, B1 in the next step. At first, the right side and left side in formula re set to zero to calculate next initial values alphaZ. alphaB. Because these value alphaA, alphaB are present at the positions shown by a drawing, a trouble point F is present in a range held between alphaA and alphaB. Next, alpha=(alphaA+alphaB)/2 is set to calculate VFA=¦VA-alphaZIA¦ and VFB=¦VB-(1-alpha)ZIS¦. That is, the potentials VFA, VFB at intermediate positions between alphaA and alphaB. ¦VFA-VFB¦ is operated from thus calculated VFA, VFB. When a preset tolerant error is set to epsilon and ¦vFA-VFB¦<=epsilon is formed, previously calculated alpha(=alphaA+alphaB/2) is set to a locating result. Against this, when ¦VFA-VFB¦>epsilon is formed, because alpha is separated from the position F of the trouble point, alpha=new alphaB is set at the time of VFA>VFB and alpha=new alphaA is set at the time of VFA<VFB to return to the previous step 2.
