Title: Optical skid-type apparatus for measuring surface roughness
Inventor: KONDO MICHIO
IPC: G01B11/30
Filed: 1989-08-23
Abstract: PURPOSE:To dispense with a costly double focus lens and to realize an inexpensive skid-type roughness gage by projecting two kinds of measuring beams, a beam of a minute spot and a ring-shaped beam, onto a surface to be measured and by detecting the amount of indentation from a phase difference between two kinds of reflection interference lights. CONSTITUTION:A laser light of a light source 10 is made to branch into a measuring light and a reference light by BS 12 and the measuring light is turned into a first beam of a minute spot and a second beam shaped in a ring by a lens 24 shaped in a truncated cone and is projected onto a sample 28. Meanwhile, the reference light is frequency-modulated by an AO module 32 and the first beam becomes an interference light together with the reference light and is converted into an electric signal by a photodetector 48, while the interference light of the second beam is converted also into an electric signal by a photodetector 54. A phase difference between the two signals is detected by a measuring circuit 56. Since the first beam contains an information on indentation and an information on vibration while the ring-shaped beam contains mainly the information on vibration, only the information on the indentation is obtained from the difference between them and a costly double focus lens can be dispensed with.

Title: Heat exchanger control device for generating plant
Inventor: MORITA MASANOBU
IPC: F03G7/04
Filed: 1987-09-01
Abstract: PURPOSE:To enable stable operation of a generating plant by cutting off the flow of a secondary medium to at least some preheater of plural preheaters as heat exchangers for preheating the secondary medium to be passed through a by-path. CONSTITUTION:While the secondary medium 10 is passed from the first preheater 8 to the sixth preheater 3, it is subjected to energy of hot water 1 to be preheated and changed into high-temperature and high-pressure vapor by an evaporator 2 to drive a turbine 11 and rotate a generator 12. Now, if the flow rate of hot water 1 is remarkably lowered than a design point, when the difference between the decreased heat exchanger duty and the heat exchanger duty decreased at the evaporating portion 2 is larger than the heat exchanger duty of the first preheater 8, according to a control signal from an arithmetic unit, a control valve 20 is closed and a control valve 24 is opened. The secondary medium 10 is passed through a by-pass line 22 not to be heat- exchanged at the first preheater 8. Accordingly, at the sixth preheater 3, the evaporation of the secondary medium can be prevented to avoid pressure change in the secondary medium system and an increase in pressure loss, so that the generating plant can be operated stably.

Title: Lead storage battery
Inventor: WATANABE KEIICHI
IPC: H01M4/62
Filed: 1982-12-09
Abstract: PURPOSE:To obtain a lead storage battery which is resistive to a deep discharging without drastic reduction of discharge characteristic of battery by covering a positive plate with a rigid layer composed of oxide particles which are resistive to acid and electro chemically inactive, inorganic binder which binds such particles and silicon rubber obtained from water silicon. CONSTITUTION:The oxides Al2O3, SiO2, CaO, ZrO, Y2O3 are resistive to acid and electrochemically inactive, while aluminum phosphateous which is hardened by dehydration, cements having hydraulic property which is hardened by addition of water and a mixture of amorphous silica and calcium hydroxide which are reversed in precipitation for water in accordance with temperature are used as the inorganic binder. When the water silicon is mixed to these rigid layer forming material and it is then dried, the silicon is not precipitated until drying is almost completed. It is porously precipitated at the particle surface in the final stage where the rigidity is completed. Moreover, while a binding force between rigidity particles is increased, formation of dense structure by closed oxide particles is prevented and a structure having distinctive transmissivity of ion can be formed through silicon rubber between particles. With employment of silicon as described above, it becomes more porous and it seems to be more effective for improvement in voltage characteristic.

Title: Wire storing device for wire transfer body
Inventor: KAWAZOE HIDEYO
IPC: B65H75/12
Filed: 1985-09-30
Abstract: PURPOSE:To increase the diameter of bend of a wire rod for preventing the wire rod from the degradation of property and disconnection by providing a winding-free portion around which the wire rod is not wound at the collar-free side of a single collared reel. CONSTITUTION:A winding-free portion 7 of a single collared reel 3 is provided at the opposite side end to the collar, i.e. the wire rod unwinding side end 6 side around which multi-layers of the wire rod 4 are wound. Thus, since the wire rod 4 is unwound to be wound around the winding-free portion 7 even in the unwinding side end 6 side, the diameter of bend of the unwound wire rod 4 is enlarged. Namely, frictional resistance is generated between the surface of the winding-free portion 7 and the wire rod 4 so that the diameter of bend of the wire rod 4 is enlarged. As a result the wire rod 4 is prevented from the property degradation and disconnection.

Title: Quantizing/inverse quantizing method for color picture element data
Inventor: YOSHIDA TETSUO
IPC: H04N11/04
Filed: 1992-08-14
Abstract: PURPOSE:To attain the optimum quantization of a color difference signal in the least number of bits by setting the range of the color difference signal in response to the level of a digital luminance signal. CONSTITUTION:A dynamic quantizing means 3 sets a quantizing range of the color difference signal in response to the level of the luminance signal quantized by a static quantizing means 1 and then quantizes again the color difference signal quantized by a static quantizing means 2 in a dynamic range. Therefore the color difference data can be expressed in the smaller number of bits compared with the conventional quantization and with no deterioration of the picture quality. Thus, the saving of a storage is attained with use of a memory which can record the information for each bit. Furthermore the data different from an original image can be multiplexed and added to the unnecessary bits even when the data are treated every 8 bits. Then a digital color difference signal can be processed in a small number of bits and this processing speed is increased in an image data handling system.

Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To classify logs by strength, by measuring weights, diametrical classes, impacts and natural frequencies of the logs on the basis of signals from a controller part of a strength-sorting apparatus and calculating strengths of logs on the basis of the measured values. SOLUTION: A log is raised and stabilized by a weight measurement first- stage cylinder at a position where the log is loaded on a log transfer wheel 3. The log is raised and a weight of the log is measured by a second-stage cylinder at a log-supporting plate fixed to a receiver instrument via a load cell. A length of a cut end of the log in a vertical direction is measured by a vertical direction diameter measurement bar, and a length in a horizontal direction is measured by a horizontal direction diameter measurement bar. The lengths are averaged, thereby obtaining a diameter. A striking apparatus 106 drives a hammer by a strike cylinder to hit the cut end of the log. A natural frequency-measuring apparatus 107 measures a tertiary resonant frequency of the sound at this time.  A Young's modulus is calculated from the diameter, weight read by a controller part 108, natural frequency and length. The log is sorted by color on the basis of a set strength class.

Title: Fluid pressure suspension
Inventor: NAKAJIMA TOMIO
IPC: B60G17/015
Filed: 1990-08-17
Abstract: PURPOSE:To restrain the unbalance in the spring constants of the front and rear wheels, even if there is a large fluctuation in the weight balance in the front and rear wheels, by providing spring-constant adjusting means by which the pressure or flow rate in second pressure chambers can be increased or decreased in response to the load fluctuation of a vehicle. CONSTITUTION:When the load on the rear side significantly increases, the mean pressure PR on the rear side exceeds a reference value PR0 and the closing of an unload valve 34 and the opening of changeover valves 64A, 64B are commanded, so that the discharge oil of a pump is introduced into the second pressure chamber inside each second accumulator 56. Thus, in the second accumulators 56 on the front right and left sides, the volume of the second pressure chamber increases to decrease the volume of the spring chamber, and the inert gas is compressed, consequently the gas spring constant increases as much as the value to be determined by the compression amount of gas. For the whole spring constant of the first and the second accumulators 54, 56, the increase in the spring constant of the second accumulators 56 results in the shift of the spring constant as much as a prescribed amount  k from a soft prescribed spring constant k1 toward the hard side, and most of the unbalance in the spring constants of the front and rear wheels can be eliminated.
