Title: Trapezoidal distortion correcting circuit for image projector using liquid crystal light valve
Inventor: SHIBAYAMA TAKECHIKA
IPC: H04N5/74
Filed: 1989-08-23
Abstract: PURPOSE:To project an image being free from the trapezoidal distortion onto a screen with simple constitution by varying monotonously the repeating frequency of a horizontal driving pulse for scanning successively one line of picture elements in a transverse direction in a vertical scanning period. CONSTITUTION:A pulse outputted from a voltage controlled oscillator 6 is supplied to a liquid crystal light valve driving circuit 13, used as a horizontal driving pulse, and as for a programmable divider 7, its frequency division ratio is changed in accordance with an up-down counter 9. In this case, a numerical output from the up-down counter 9 is converted to the control signal of magnitude corresponding to a numerical value by a digital/analog converter 11, it is supplied to a monostable multivibrator 12 whose output pulse width is variable by the control signal, triggered by a horizontal synchronizing signal Sh supplied from a terminal 3 and the time point of the fall of the pulse becomes a time point for starting write. In such a manner, an image being free from the trapezoidal distortion can be reflected on a screen with the simple constitution.

Title: Laser driving circuit for image forming apparatus
Inventor: SAKATA SHIRO
IPC: B41J2/44
Filed: 1994-09-12
Abstract: PURPOSE: To reduce the overshoot of a light waveform generated at the time of switching a laser diode by selecting a switching circuit to be driven and decided according to a current value, a voltage value, a resistance value and a threshold value from a plurality of switching circuits of switching means. CONSTITUTION: A voltage between the terminals of a laser diode 100, a driving current are detected, recorded and calculated in light quantity control means, and the resistance component of the diode 100 is obtained. If the obtained value is larger than a reference value, the switching circuit 101 connected with no resistor is selected, while if the obtained value is smaller than the reference value (threshold value), the circuit 101 connected with the resistor is selected, and switched. Thus, the unevenness of the individual laser diode resistances are reduced, the light quantity change due to the overshoot can be suppressed to the minimum limit. Accordingly, an image of high image quantity and high accuracy can be formed.

Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To improve the maintainability of the title surface processor by a method wherein a guide for guiding a work is provided on a base, a lid having an open lower part and defining a closed spase when the lid is brought into contact with the base is so supported as to be lowered in a horizontal posture and lifted in a vertical posture and is brought into contact with the base and separated from the base. SOLUTION: When a lid 13 having an opened lower part and so supperted as to be brought into contact with a base 12 and separated therefrom is brought into contact with the base forming a part of a transfer path L, a closed space is defined on the transfer path L. A pair of guides 18 guides a work 6 along the transfer path L from the upper stream side than a wire bonding part 14 to a recovery magazine 10. At this time, the lid 13 is held and capable of taking three states: a state that it is lowered in a horizontal posture, a state that it is lifted in a horizontal posture, and a state that it is lifted in a vertical posture. For example, in order to put the lid 13 in a horizontal posture, a cylinder 23 is driven to protrude a rod 23a. Through these procedures, the lid 13 can be lifted from the base 2 leaving intact in a horizontal posture.

Title: Error control ciphering system
Inventor: NAKAI TOSHIHISA
IPC: H04L1/00
Filed: 1984-10-18
Abstract: PURPOSE:To eliminate burst error at decoding by converting a q dimension information inputted at the transmission side into a q<m> dimension information taking values of 0-q<m>-1 at each m sets at a q q<m> converting section. CONSTITUTION:A two-dimension data series is inputted from an input terminal 10 at first. A data i1 is inputted to a q q<m> dimension converting section 11 and converted into i2=(0,8,14,2,2,2,11,11,5,9,0). The q q<m> dimension conversion section 11 converts a signal at each 4 bits before the i1 as a set to a hexadecimal number. The i1=(0,8,14,2,2,2,11,11,5,9,0) is outputted from an error control decoding section 18. The data i1 inputted from the input terminal 10 is subjected to error control coding and ciphering by transmission q q<m> dimension converting section 11-q<m> dimension converting section 14 and transmitted to a transmission line 15 as a v3. Even if a burst error (e) takes place in the transmission line, the error control (correction) is applied at the reception side to obtain the i2. This means that the transmission/reception of a correct data with i2=i1 not affected by the burst error (e) is attained.

Title: Exhaust heat exchanger
Inventor: SHIBAGAKI KAZUHIRO
IPC: F02M25/07
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent the pressure loss and accumulation of particulates in an exhaust gas tube. SOLUTION: The direction SD of segments 112 is tilted in the opposite direction of a diagonal line L1 connecting the cooling water communicating paths 120b with respect to the longitudinal direction of an exhaust gas tube 110. Thus, since the cross angle between the direction SD of the segments 112 and the main flow of EGR gas becomes smaller, the pressure loss generated when the EGR gas circulates in the exhaust gas tube 110, can be reduced. Further, since particulates adhered to the segments 112 are separated by the EGR gas flow colliding with the wall face of the segments 112, and the particulates accumulated just below the rear flow of the segments 112 are forcedly allowed to flow down to the downstream by the EGR gas flow traversing between the segments 112, the particulates can be prevented from being accumulated in fins 111 (the exhaust gas tube 110).
