Title: Overdischarging preventer of battery pack
Inventor: MATSUKI TSUTOMU
IPC: H02J7/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent overdischarging of battery pack by forecasting overdischarging. SOLUTION: This overdischarging preventer of a battery pack detects the voltage Vn of each battery of a battery pack constituted by connecting a plurality of batteries in series (step S104), and obtains the lowest voltage Vmin (step S106, and also obtains the maximum drop rate dVmax and sets a threshold Vβ (step S112). Since the threshold Vβ is one being set as a value for forecasting the battery becoming overcharged within a specified time, if the battery of the voltage under the value drops in voltage at a maximum drop rate dVmax, this preventer decides that the overdischarging is forecast, when the lowest voltage Vmin is under the threshold Vβ (step S114), and stops the supply of power from the battery pack (step S116). As a result, this prevents a battery constituting the battery pack from becoming overdischarged.

Title: Fine particle having uniform particle size and production thereof
Inventor: ASANO TADASHI
IPC: C08F291/00
Filed: 1985-03-30
Abstract: PURPOSE:To obtain fine particles having a uniform particle size and such a structure that a crosslinked polymer is added to fine particle of a high-molecular material, by adding an aq. dispersion of a mixture of a crosslinking monomer and a non- crosslinking monomer to a dispersion of fine particles of a high-molecular material and carrying out a polymn. reaction in the presence of a polymn. initiator. CONSTITUTION:An aq. dispersion of a monomer mixture of a crosslinking monomer and a non-crosslinking monomer is added to a dispersion of fine particles of a high- molecular material having a particle size of 20mu or below and standard deviation in particle size distribution of 0.5mu or below in a quantity of 100-3,000pts.wt. monomer mixture per 100pts.wt. fine particle. The mixture is polymerized in the presence of an oil-soluble polymn. initiator by quickly heating it to the decomposition temp. of said initiator. Preferred examples of the non-crosslinking monomers are methylstyrene and butyl methacrylate. As the crosslinking monomer, one having low solubility in water, such as divinylbenzene is preferred. A monomer having high solubility in water is not preferred, because new particles other than seed particle are formed during the course of polymn. treatment.

Title: Position controller
Inventor: KAMIYAMA MASAHIKO
IPC: G05B19/19
Filed: 1987-03-24
Abstract: PURPOSE:To prevent the movement of a device after a forcible stop state set by a forcible stop switch is released by changing a target value signal into a position detecting signal received from a position detector at the relevant time point via a target changing circuit when the forcible stop switch is turned on. CONSTITUTION:When a forcible stop switch 15 is turned on, a signal s16 is outputted to a position controller 6 and an action similar to that carried out when a target position is secured owing to a fact that the output of the controller 6 is set at zero. Thus, a device 9 is stopped. At the same time, a relay 103 is energized to close an (a) contact 104 and also to switch a changeover switch 105 to an (a) side terminal. Then, a position detecting signal s13 received from a position detector 10 is supplied to an adder 102 together with a target value signal s3b given from a D/A converter 3. The adder 102 obtains a difference of both signals for production of a difference signal s106 and outputs this signal s106 to an adder 101. The signal s106 shows the difference between the actual position and the target one of the device 9.

Title: Multibeam scanning device and image forming device
Inventor: AMADA MIGAKU
IPC: G03G15/04
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of image due to the difference of writing widths by decreasing the difference of scanning positions in plural beams scanning a surface to be scanned or reducing the difference of scanning line lengths (writing widths) of the respective beams on the surface to be scanned during one line of scanning in a multibeam scanning device. SOLUTION: In a multibeam scanning device having at least a light source part 10 arranging plural light emitting parts at least in the sub-scanning direction, a light deflector 30 for scanning plural light beams from the light source part 10 on a surface to be scanned 50 and a constant-speed light scanning/image forming mirror 41 for uniformly scanning the surface to be scanned with the beams, scanning is performed by successively shifting the write starting position of each beam on the surface to be scanned. Consequently, by making write starting and ending positions almost symmetric to the center of writing width, the difference of scanning positions at the same time is reduced to all writing widths.

Title: Focusing device
Inventor: KUGA RIYUUICHIROU
IPC: G03B13/36
Filed: 1983-04-18
Abstract: PURPOSE:To raise the focusing accuracy even in case the intensity of illumination of an object to be photographed is low by generating an optical output corresponding to an infrared optical image and a visible optical image of the object to be photographed, and generating a control signal for indicating a focused position of a photographic optical system to the object to be photographed. CONSTITUTION:An image of an object to be photographed is formed on photodetectors 9a, 9b through focusing optical system 10a, 10b. An operating part 14 receives an output signal of the elements 9a, 9b, and drives an image pickup optical system 7. As the image pickup optical system is driven, an image formed position of the image of the object to be photographed on the photodetectors 9a, 9b approaches a focused state. When the outputs of the photodetectors 9a, 9b are balanced, a signal of a driving stop is outputted from the operating part 14, and the focusing work is completed. By irradiating the object to be photographed by an infrared ray from a projecting part 8, it is possible to execute the focusing whose accuracy does not exert influence on the intensity of illumination of the object to be photographed. In this way, even in a state that the intensity of the object to be photographed is low, the focusing can be executed without dropping the focusing accuracy.

Title: Method and apparatus for processing time sequence of audible signal and sequence decoding method of coded signal
Inventor: KAARUHAITSU BURANDENBAAGU
IPC: G10L19/035
Filed: 1991-03-08
Abstract: PURPOSE: To obtain adaptivity more suitable for human ears by modeling ears as a filter bank having different pieces of time resolution and different pieces of frequency resolution. CONSTITUTION: Respective QMF tree filter banks 201 to 203 are used for obtaining four channels having 3 to 12kHz band width (frequency resolution), i.e., 2 to 8hr time resolution. Output signals from the banks 201 to 203 use window conversion in order to obtain calculation filter banks 210 to 213 having much more channels. The window is a sine window using a 50% overlapped analytical block and two different conversion methods are used. The filter banks combining the two different conversion methods have 23.4Hz frequency resolution in low frequency and 187.5Hz frequency resolution in high frequency and have correspondingly different pieces of time resolution. Although the time resolution is quantized up to power of 2, the range of time/frequency resolution is increased by the advancement of an analytical/synthetic method and the quantization is reduced.

Filed: 1992-03-26
Abstract: PURPOSE:To provide a modular jack outlet, with which such a condition can simply be checked that the wiring at the terminating part of a LAN remains off connecting or that the information wiring is in severance. CONSTITUTION:Conductive components B1, B2 for loop-back are furnished to generate the loop-back condition by connecting contacts C in connection with transmitting signal lines 1, 2 with corresponding contacts C in connection with receiving signal lines 3, 6 while a modular plug connector remains off mounting.
