Title: Spacer for optical fiber cable and optical fiber cable utilizing this spacer
Inventor: TAKAHASHI SEIICHIRO
IPC: G02B6/44
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To relieve the elongation strain of coated optical fibers. SOLUTION: Grooves 2 for housing the coated optical fibers disposed at the spacer 1 constitute S-Z grooves alternately continuously formed with S-shaped groove parts which meander to an S-shape in the longitudinal direction of the spacer 1 and Z-shaped groove parts which meander to an approximately Z shape. Inter-groove filamentary bodies 12 are provided between S-Z grooves. Inter-groove filamentary bodies 12 are formed of materials having the coefficient of longitudinal elasticity higher than the coefficient of longitudinal elasticity in the forming regions of the S-Z grooves 2 and the forming regions of the S-Z grooves 2 are formed of materials having the coefficient of transverse elasticity smaller than the coefficient of transverse elasticity of the materials of the inter-groove filamentary bodies 12.  When tension is applied on the spacer 1 and elongation occurs therein, the force in the direction where the meandering shape is deformed to a straight shape is acts on the inter-groove filamentary bodies 12, by which the S-Z grooves 2 are deformed to a direction advancing for the straight shape. The elongation rate of the S-Z grooves 2 is suppressed and the tension acting on the coated optical fibers is decreased, by which the elongation strain of the coated optical fibers is relieved.

Title: Dc power supply system
Inventor: BABASAKI TADATOSHI
IPC: H01M8/04
Filed: 1991-11-15
Abstract: PURPOSE:To control the output of a fuel cell to the maximum output power at all times by installing a power device whose input is connected to the fuel cell and which is provided with a drooping function for controlling the output power of the fuel cell at constant or an input power controlling function. CONSTITUTION:If the total quantity of current to be supplied to the load 5 is I0A, I0A=I1+I2 since I1A is supplied from a power device 2 and I2A is supplied from a rectifier 4. When the power consumption of the load 5 increases and the total current I0A increases by DELTAI0, the power device 2 controls a drooping characteristic of the output voltage to make the output power constant and thereby the output P1 of a first system power supply A becomes constant. As a result, the power device 2 comes to have an arc curve which is a changed constant power curve and it bears part of the output current. In other words, by controlling the input power or output power of the power device 2 at constant, the output of a d.c. power supply can be controlled to the maximum output power at all times and the d.c. power supply can quite efficiently be used including cogeneration with thermal energy.

Hereby, variations of the amount of blow water are reduced by making use of two modes of blows: a continuous blow where water is discharged at a predetermined flow speed at all times and an intermittent blow where water is discharged interlocking with the conductivity.  Load variations of a blow waste water pressing apparatus are reduced and hence operation control is facilitated. Chemical feeding is controlled in response to each of the two modes of the blows so that variations of chemical concentration in cooling water are reduced. Processing effect of a chemical can be stably and effectually obtained.

Abstract: PURPOSE:To perform motion detection which is hardly affected by noise mixed in video signals by controlling the characteristic of a coring circuit and passing band characteristic of an interframe difference signal based on the luminance level of extracted input video signals. CONSTITUTION:Luminance signals inputted to an input terminal 50 are supplied to a frame delaying device 51 where the signals are delayed by one frame and further supplied to a subtractor 52 where the one-frame delayed signals are subtracted from the original signals. As a result, interframe difference signals which indicate the information about the motion or magnitude of the motion of the input luminance signals are inputted to a coring circuit 55 through an LPF 53 and absolute value circuit 54. On the other hand, the luminance signals are also inputted to a luminance level detection circuit 50 from the terminal 50 and the luminance level of the signals is detected at every field or in a fixed two-dimensional area. By using the luminance detecting signal of the circuit 60, the passing band characteristic of the interframe difference signal of the LPF 53 is controlled and, at the same time, the circuit 55 controls the threshold level when the circuit discriminates still pictures and moving pictures from each other by using a luminance level signal.

Abstract: PURPOSE:To correct density irregularities in a shorter time by a method wherein density irregularities are corrected by a density irregularities correction means on the basis of the density irregularities distribution of a read test pattern, and a gradation is corrected by a gradation correction means based on gradation correction information inputted from an input means. CONSTITUTION:An optimum gradation correction table for every head has been found in a characteristic test conducted after the production of the heads and labeled or marked on each of the heads. When the heads are loaded, an operator refers to this indication and inputs a gradation correction selecting signal to an address of a gradation correction table from gradation correction table setting parts 103a - 103c to select an optimum table. For example, when the gradation characteristic of the head is shown by a curve B, a gradation correction table as shown by a curve A is selected, whereby a relation between an input signal and an image density is corrected to be linear as shown by a straight line C. When the gradation characteristic of the head is shown by a curve E, a gradation correction table as shown by a curve D is selected, whereby a gradation is corrected to be linear as shown by a straight line C. In this manner, density irregularities correction data can be formed in a short time.

Title: Connecting method of thin battery
Inventor: ITO TAKASHI
IPC: H01M2/20
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce the ratio of the sealed parts of unit cells in a collected battery by mutually superposing the sealed parts of the unit cells. SOLUTION: A unit cell is manufactured by the use of a positive electrode 1, a negative electrode 2, and a separator 3, and an aluminum laminate sheet 5 having an outside molded in advance into a protruding part and a general aluminum laminate sheet 4 are welded thereto. Thus, the unit cell in which a sealed part is shifted from the thickness central line of a battery is completed. The completed unit cells are connected alternately to each other, so that the sealed parts of the adjacent batteries are mutually superposed and flatly continued, whereby the connection of thin batteries is completed. Consequently, the sealed part width of the unit cell is halved substantially, and the energy density is improved.  Since the total thickness of the batteries is the same as in the unit cell thickness where they are serially connected, the overall equipment can be thinned in the mounting on a personal computer or the like.
