Title: Apparatus and method for regulating joint in split plotting
Inventor: USUMOTO HIROAKI
IPC: B41C1/05
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To easily regulate a joint between areas in split plotting in a short time. SOLUTION: This apparatus moves an exposure head 1 to position a beam image of dots substantially at a center of a CCD camera 2. A laser beam is scanned in one stripe area by the head 1 while lighting the beam at all the dots, the image is input as image data by the camera 2, and the beam is scanned in the other stripe area by the head 1 while lighting the beam at all the dots, and the image is input as image data by the camera 2. The image data are combined to form synthetic data. A light amount distribution at a joint is calculated based on the synthetic data. Whether the distribution falls within a predetermined range or not is decided. When it does not fall within the range, scanning width of the head 1 is altered, and this process is repeated.

Filed: 1993-12-17
Abstract: PURPOSE: To provide an optical device which has aberrations improved furthermore by rotating a compensation plate around a beam axis at a prescribed angle to an optical element to completely eliminate the astigmatism due to the optical element. CONSTITUTION: A filter or an element 1 like a plate is arranged on an optical axis 0-0.

Title: District heat supply system
Inventor: KATAYAMA MASATO
IPC: F24F5/00
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a district heat supply system to flexibly cope with change of a heat demand amount by coping with the increase of a heat demand amount through the increase of a temperature difference between heating media. SOLUTION: This district heat supply system is formed such that a heat supply plant and heat consumers are interconnected through a circulation line comprising a supply line and a return line for a heating medium. A temperature difference between the supply line for the heating medium and the heating medium in the return line is regulated according to the increase or decrease of heat demand.

Abstract: PURPOSE: To easily produce a liquid crystal electro-optical element using a ferroelectric liquid crystal by heating a ferroelectric liquid crystal to change into an isotropic liquid, injecting the liquid into the space between a pair of electrode substrates, and cooling the liquid to change the ferroelectric liquid crystal into a chiral smectic phase. CONSTITUTION: Polymer orienting films 1b, 2b are formed on the inside surfaces of transparent electrodes 1a, 2a, respectively, comprising conductive films formed on the surfaces of transparent substrates. The orienting films 1b, 2b are subjected to orientation treatment to align the liquid crystal molecules parallel to the substrates. A ferroelectric liquid crystal material in an isotropic liquid state prepared by heating is injected by using a capillary action into the space between the electrode substrates 1, 2 having the structure above described. After injection, the whole liquid crystal cell is slowly cooled at 0.1 to 1.0C per min. cooling rate to obtain a chiral smectic C phase. The ferroelectric liquid crystal molecules in the chiral smectic C phase as the result of cooling are automatically oriented because of the large polarity of the liquid crystal molecule itself.

Abstract: PROBLEM TO BE SOLVED: To reduce the incidence of an erroneous operation by constituting a gate circuit for a suppression circuit of a second transistor whose impedance is lower than an IC and obtaining a power supply for the second transistor from a motor terminal. SOLUTION: In a state that printing solenoid drive signals 43-45 from CPU 8 are at a LOW level and a motor drive terminal 7 is at a HIGH level, and a motor 36 is being driven, voltage is applied to the emitters of PNP transistors 20, 25, 29, 33 which work also as suppression circuits.
