Title: Reciprocating engine
Inventor: OGASAWARA TOSHIO
IPC: F16J1/18
Filed: 1990-10-02
Abstract: PURPOSE:To improve the strength of a ceramic piston pin by specifying the assembling direction of the ceramic piston pin to the moving direction of a piston at the time of assembling the ceramic piston pin to the piston in order to connect the piston to the small end part of a connecting rod. CONSTITUTION:The assembling direction of a ceramic piston pin 2 to the moving direction of a piston 1 is specified at the time of assembling the ceramic piston pin 2 to the piston 1 in order to connect the piston 1 to the small end part of a connecting rod 4. The ceramic piston pin 2 is thereby prevented from receiving large bending force in its whole surface. As a result, the characteristic volume effect of ceramic is not revealed, so that the breaking probability of the ceramic piston pin 2 is lowered, and thus the strength of the ceramic piston pin 2 is improved.

Title: Method for detecting luminance unevenness of display element
Inventor: KATSUTA DAISUKE
IPC: G01N21/93
Filed: 1992-10-02
Abstract: PURPOSE:To provide an inspection method for discriminating a natural steady luminance unevenness caused by an illuminator from a defective luminance unevenness in a display element for liquid crystal display board, and detecting only the defective luminance unevenness. CONSTITUTION:The image of a liquid crystal display board having a defective luminance unevenness is inputted by a television camera, binarized, and then converted into a block pattern of (n)X(m). This block pattern is compared with the block pattern of a good product to extract the defective luminance unevenness. Thus, the defective luminance unevenness of a display element for liquid crystal display board is detected at high speed by using no memory without erroneously judging a luminance unevenness naturally present by an illuminator.

Title: Light emitting element with function of correcting light emission output
Inventor: FUJIEDA ICHIRO
IPC: H05B44/00
Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a small and easy-to-manufacture light emitting element for use in an electrophotographic printer and an emissive display, with the light emission output of the light emitting element being corrected for aged deterioration of the light emitting element and variations in characteristics. SOLUTION: A light emitting part 1 and a light detecting part 2 for detecting the emission output of light emitted by the light emitting part 1 are formed on the same substrate 10 and a portion of the light emitted by the light emitting part 1 impinges on the light detecting part 2. A light emission output control means comprising a thin-film transistor (TFT) 3 or the like corrects the light emission output of the light emitting part 1 based on the detection output of the light detecting part 2. The desired light emission output can be stably obtained irrespective of aged deterioration of light emission means and a difference in characteristic between the individual light emission means.  Also, processes such as positioning and bonding are not required during assembly, as are necessary for an arrangement such that the light emitting part 1 and the light detecting part 2 are constructed as independent parts and assembled together. Therefore, an increase in manufacturing cost and decreases in yields and reliability can be prevented.

Title: Optical system equipped with moving optical element
Inventor: YAMAZAKI SHOICHI
IPC: G02B9/00
Filed: 1986-11-06
Abstract: PURPOSE:To attain the effective movement of an image with small eccentricity by arranging a moving optical element satisfying a specific condition between the horizontal magnification of a moving optical element and the magnification of an optical element on the image side. CONSTITUTION:When it is defined that the horizontal magnification of the moving element is betaa and the magnification of the optical element on the image side is betab (provided that when no optical element exists on the image side, betab=1), ¦betab(1-betaa)¦>=1 is satisfied. An image forming lens system consists of a 1st focal lens 5, a 2nd lens group 6 and a 3rd lens group 7 in order and each lens group consists of one or plural lenses. The 2nd lens group 6 is supported by a supporting device so that parallel eccentricity can be optionally attained in the direction vertical to the optical axis of the image forming lens system and is enabled to be two-dimensionally driven by an actuator 3 such as a piezoelectric element. Since a purpose can be attained only by the short movement of the moving part, a space for the movement can be reduced, the whole device can be miniaturized and accurate follow-up to the moving part can be attained also at a high frequency level or a large amplitude value because the moving distance is small.

Title: Electronic cash processor
Inventor: IWAGAMI KENJI
IPC: G07G1/12
Filed: 1990-10-02
Abstract: PURPOSE:To automatically recover the operation of the cash processor in a short period even when runaway occurs by performing reset when measured time necessary for calculation processing operation exceeds time to be set in advance. CONSTITUTION:When abnormality occurs in a program to cause the runaway in a calculation processing means 1, a confirmation signal for each one second is not outputted. Therefore, a monitoring means 13 leads out an indication signal indicating the output of a reset signal through a line 14 against a reset signal generation circuit 8 when the confirmation signal is not received over one second through a line 12. Therefore, the reset signal generation circuit 8 supplies a reset signal through a line 9 to the calculation processing means 1, the calculation processing means 1 performs the reset operation, and the operation of this electronics cash register can be performed again. Thus, even when the runaway of the program occurs, the operation can be automatically recovered in a short period.
