Title: Phase locked loop circuit
Inventor: SHINABE MUNEHIRO
IPC: H03L7/107
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to accurately grasp a switch timing through the addition of a simple circuit with respect to the phase locked loop circuit whose loop filter constant is changed between an initial frequency lock state and a steady-state. SOLUTION: A phase difference signal resulting from comparison between an input signal 101 and an output of a voltage controlled oscillator 109 is multiplied with constants α0, β0 at multipliers 104, 105 respectively in the initial frequency lock state. Outputs of an integration device 106 and the multiplier 105 are added and smoothed to make an output of the voltage controlled oscillator 109 close to the input signal 101. A sample-and-hold circuit 112, a storage element 113, a subtractor 114 and an absolute value circuit 115 are used to obtain a change in the integration signal 107 per unit time. When the change is smaller than a prescribed value γ, it is discriminated that the state is a steady-state and new constants α1, β1 are used.

Abstract: PURPOSE:To enable sample slices to be cut with the temperature thereof maintained accurately, by a method wherein a metal foil plate supporting sample slices fitted in slits in instantaneously pressure-bonded by two metal blocks cooled to ultralow temperature to form a glasslike frozen layer having no formation of cryohydrate on the surface. CONSTITUTION:Living body slices 1 are fitted in a plurality of slits in a metal foil plate 3 of excellent heat conductivity. After metal blocks 7 and 8 have been cooled in a cooling chamber 4, an electromagnet 10 is operated to raise the metal block 8, and a supporting base 12 is fitted. The metal foil plate 3 is placed on a supporting member 20, which is attached to the lower end of a cylinder 6 by using a rubber band 21, and a lid-shaped body 5 is lowered to cover the cooling chamber 4. A rod-shaped weight 11 is inserted into the cylinder 6, and the metal block 8 and the metal foil plate 3 are made to drop. Consequently, the slices 1 are pressure-bonded from both sides by means of the cooled metal blocks 7 and 8 and instantaneously frozen to form a glasslike frozen layer 2 having no formation of cryohydrate. The slices 1 are made to bite into the metal foil plate 3 and firmly fixed, each being formed into an I-shape. Accordingly, controlling the temperature of the metal foil plate 3 permits that of the slices to be controlled.

Title: Power consumption control system
Inventor: NAGAOKA MASAYUKI
IPC: G06F1/28
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent the excessive consumption or power and to prevent the cut of a breaker by controlling the operation of respective devices in accordance with a comparison result between the total value of the power consumption of the respective devices and the maximum value of power consumption and keeping power consumption to be constant. SOLUTION: Maximum power consumption at which the device aims is set in a device power consumption register 21. An addition circuit 26 calculates present power consumption based on respective registers 22-25 detecting the power consumption of CPU, HDD, CRT and the other devices, and a comparison circuit 27 compares the calculated result with a maximum power consumption value which is set in the register 21. When the value of the register 21 is larger than the value of the addition circuit 26 and a difference more than a prescribed value is generated, a whole control circuit 28 relieves the suppression of power consumption for one of four circuits from a CPU control circuit 29 to the other control circuit 32. In the opposite case, an instruction for suppressing power consumption is given. Thus, maximum performance can be realized within the range of power consumption which is set.

Title: Solar pond
Inventor: SEKIYA EIJI
IPC: F24J2/00
Filed: 1986-03-20
Abstract: PURPOSE:To provide a solar pond in which the cost required for a solute is suppressed, the gradient of density of water in the pond even in a high temperature heat storage is stable, and the operation and management are easy, by properly using the kind of a solute at each temperature level for a plurality of solar ponds having different heat storage temperatures. CONSTITUTION:The number of solar ponds are set to a plurality, and the solution in the pond is constituted of different solutes. The concentration gradient is formed by NaCl in a solar pond A for low temperatures and by NH4NO3 in a solar pond B for high temperatures. The solubility of NaCl is substantially constant with respect to the temperature. The solubility of NH4NO3 (ammonium nitrate) or KNO3 is rapidly increased in accordance with the temperature. Since the amount thereof soluble in water of low temperatures is small, the density gradient within the solar pond is inevitably maintained. Fresh water or a low- boiling point medium whose pressure has been raised receives heat at the heat exchanger 5a for low temperatures of the solar pond B for low temperatures and is heated to a certain temperature, and then further heated by a heat exchanger 5b for high temperatures of the solar pond B for high temperatures, and reaches a target temperature and is supplied to a heat load 6.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To improve the erosion resistance and the heat cycle resistance of a casting member used in the contact part with molten metal and the heat retaining property of the molten metal by forming a chromium nitride film having a specific density on the surface of a base material of the casting member. SOLUTION: The density of the chromium nitride film is regulated to >=6.40 g/cm<3> N content in the chromium nitride film is 30-55 atomic % and further, it is desirable that the base material of the member for casting is made of Ti or Ti alloy. The chromium nitride film is formed by a cathode discharging type AIP method (arc ion plating method) and further, this member is desirable to be used for molten Al or Al alloy. Since the AIP method is executed so as to vaporize and ionize a target with the large current arc, the ionizing efficiency is high and the chromium nitride film excellent in closeness and adhesivility can be obtd.  The N in the film can be adjusted by adjusting the pressure of reaction gas, and since the coating temp. is 300-500 deg.C, which is lower than the βtransformation point of the Ti or Ti alloy at 800-950 deg.C, the thermal stress and the lowering of strength are not developed in the Ti or the Ti alloy.

Title: Optical isolator of optical fiber
Inventor: TAKEMURA YASUHIRO
IPC: G02B6/00
Filed: 1987-03-17
Abstract: PURPOSE:To obtain an isolator which is small in size, does not require alignment of optical axes, etc., and permits easy assembly by combining a polarizer or polarized beam splitter and quarter wavelength delaying element constituted of optical fibers. CONSTITUTION:The luminous flux from a light source 1 which enters the optical fiber polarizer 6 or the optical fiber polarized beam splitter after passing an incident optical system is made into the propagated light in which a transverse modes rises only in the direction nearly along the axis of polarization of the optical fiber polarizing element 6. This light is propagated through the optical fiber connector part 8 or welded part to the optical fiber quarter wavelength delaying element 7. The light passes the quarter wavelength delaying element 7 again when the light propagated from the element 7 through the connector 8 and the welded part, etc. to the propagation- or optical system behind the same and returns. The synthesized mode thereof is thereby made to the mode orthogonal with the axis of polarization of the element 6 and the propagation to the light source side is prohibited. The function of the isolator is thus obtd. The reduction in the size of the optical system is thereby permitted, by which the axial alignment of light and the assembly are facilitated.
