Title: Automatic equalizer
IPC: H04B3/23
Filed: 1992-03-11
Abstract: PURPOSE:To reduce the cost of the automatic equalizer by reducing the scale of an equalization circuit in the automatic equalizer which eliminates linear distortion of a signal resulting from orthogonal-modulating a video signal and a digital data signal with a symbol period T. CONSTITUTION:An equalizer circuit 14 consists of series connection of an I axis use transversal filter whose tap interval is T/2, a Q axis use short transversal filter whose tap interval is T/2, and a Q axis use transversal filter whose tap interval is T. A CPU 23 employs a RAM 21 and a ROM 22 and implements correlation calculation and tap coefficient correction calculation or the like based on signals before and after I axis waveform equalization and on signals before and after Q axis waveform equalization to correct the tap coefficient of the equalization circuit 14. A digital data signal whose linear distortion is eliminated is outputted from the equalization circuit 14 by implementing the operation above for a prescribed number of times.

Title: Mechanism for positioning optical element of variable power image recorder
Inventor: TOOYAMA YOSHIKUNI
IPC: G03B27/34
Filed: 1982-03-31
Abstract: PURPOSE:To enable the setting of lens or mirror in multistage positions by controlling only the movement of the lens or the mirror by providing an intermediate stopper construction which functions as a stopper automatically and mechanically or releases said function. CONSTITUTION:When a lens base 2 is moved by the rotation of a pulley 9 in a direction A, a positioning pin 4 starts moving and advances beyond the stopper part 19 of a stopper member. When the rotation of the pulley 9 is changed to a direction C, the 1st engaging surface 19a of the stopper part 19 regulates the movement of the pin 4, thereby defining the set position of the base 2. In other words, a stopper member 15 functions indpendently always as a stopper in the backward direction with respect to the movement of the pin 4 and permits always the passage of the pin in the forward direction. The above-desscribed movement of the pin 4, that is, the movement of the base 2 is set beforehand in the control circuit for driving a reversible motor 6.

Title: Parameter setting device
Inventor: MISHIMA JUNICHI
IPC: G10H1/24
Filed: 1989-03-07
Abstract: PURPOSE:To set a parameter level roughly and finely with a small number of operation switches by providing plural parameter setting switches. CONSTITUTION:When one of the parameter setting switches VSW1-VSW5, e.g. VSW4 is depressed, parameter value rough setting means PD1-PD5 set specific parameter values determined in respective groups obtained by dividing all possible values as parameters according to the large-small relation. Nearly simultaneously with the depression of one of the parameter setting switches VSW1-VSW5, e.g. VSW4, parameter value fine setting means 5 and 6 set finely parameter values in the groups including the parameter values set by the parameter value rough setting means PD1-PD5 when a parameter setting switch VSW3 or VSW5 adjoining to the depressed switch VSW4 is depressed. Consequently, the parameter values can be set roughly and finely only with the switches for parameter value setting, and the operation is extremely easy.

Abstract: PURPOSE:To reduce the overhead of a test and set instruction and adapt a system easily to addition of data by preparing common access inhibiting flags writably in accordance with storage areas to which a common memory is divided fixedly. CONSTITUTION:Data A is stored divisionally in areas P0, P1, and P2 on a common memory 1 which plural access request sources access. Flags TASF (common access inhibiting flag)-P0-TASF-P2 corresponding to divided storage areas P0-P2 in 1:1 are prepared in a TASF table 4 through a common memory access register 2. If the value of the TASF-P0 is all ''1'', a request source #i is written on the table 4, and data on the storage area P0 is fetched from the common memory to a main storage device 9. During this fetch, another access request source #j is inhibited from accessing the storage area P0.

The plate 65 is constituted by printing dots 65a having high density at a position opposed to the front of the lamp 63 and dots 65b having low density around the dots 65a. In the case of exposure, the lamp 63 emits the light and the large quantity of light at the part opposed to the lamp 63 is transmitted through the dots 65a and largely reduced. The small quantity of light around the opposed part to the lamp 63 is transmitted to the dots 65b and is not reduced so much. Then, the exposure is performed with the nearly uniform quantity of light.

Title: Method for controlling facsimile reception section
Inventor: KIKUCHI MASAYUKI
IPC: H04N1/32
Filed: 1985-03-19
Abstract: PURPOSE:To decrease the reception error by deciding the data signal speed based on both the result of discrimination of a TCF signal and of data signal detection at no signal. CONSTITUTION:When a line is connected, a reception station sends a DIS signal representing the capability of a terminal station. Then a DCS signal representing the transmission condition from a transmission station is received and the detection of data signal (CD) is discriminated at a signal pause period after the end of the DCS signal. Then a high speed sequence TCF from the transmission station is received and when the CD signal is set, since it shows that the line has much noise, even when the result of discrimination of the TCF signal is successful, the ETT signal is sent back while the data signal speed is other than 4,800BPS to inform difficulty of communication. Thus, the possibility of reception error is reduced even during a picture is received.

Abstract: PROBLEM TO BE SOLVED: To reduce vibration in two directions, further, in three directions by a single dynamic vibration reducer by using cylindrical and disk-shaped magnets in a movable part, fixing similar magnets whose polarities are reversed to the car side, and constituting the dynamic vibration reducer. SOLUTION: A dynamic vibration reducer 5 is composed of a movable part (a weight) 6, a fixing part 7 and a spacer (a vibration absorbing plate) 8. The movable part 6 is composed of two kinds of magnets 9 and 10, and the fixing part 7 is composed of magnets 11 and 12 having reverse polarity in a place corresponding to positions of the magnets 9 and 10. When the movable part 6 moves in the shearing direction, magnetic attraction force and repulsive force generated between this movable part 6 and the fixing part 7, correspond to a spring (an elastic body) in the dynamic vibration reducer 5, and an eddy current generated in the spacer 8 made of a conductive plate, acts as a damping element in the dynamic vibration reducer 5. When the dynamic vibration reducer 5 is installed in a car frame lower beam part, vibration is damped in two directions of the X and Y directions.  It can cope with various vibration modes by installing a single piece or plural pieces not only in the lower beam part but also in an upper beam part, under a floor of a car, on the ceiling or the like.
