Title: Current adjusting circuit by zap
Inventor: KAKUMOTO YASUNOBU
IPC: G05F3/26
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a precise output by eliminating the influence of size reduction due to IC implementation and residual resistance after writing by providing a Zener diode which is connected as a reverse bias in series between a 4th resistor and the ground. SOLUTION: When a reference voltage is applied, the sum current of the collector current Ia of a transistor 22 and the current Ib flowing to a current mirror circuit flows as an output current Io. When a high voltage is applied to a pin at this time, the Zener diode 34 is broken to cause short-circuiting, so a current begins to flow to a resistance 33 and then the current mirror circuit does not operate. Consequently, only the current Ia flows as an output current through the collector of the transistor 22. The resistance 33 is irrelevant to the precision of the output current, so it may be a low-precision resistance and a small layout can be obtained. Further, a current leaking from the resistance 33 can be absorbed by diodes 30, 31, and 32, so stable writing is enabled without exerting any influence on other circuits while the power source is held ON.

Title: Measuring method for range of partial crystallization at bottom and measuring apparatus therefor
Inventor: TAKEI ATSUSHI
IPC: H04N7/18
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To reliably judge that whether a partial whitening crystallization region at a bottom of a self-supporting container is proper, by fetching transmitted light, which has been transmitted through the bottom, as the intensity of transmitted light for each pixel in a CCD in a measuring apparatus, finding out and calculating frequency distributions of the intensity of transmitted light for the whole pixels, and determining the center of gravity thereof. SOLUTION: In a process by an image processor 13, transmitted light from an illumination 11, which has been transmitted through a bottom of a self-supporting container 1 and two polarizing plates 21, 22, is fetched as luminance data on transmitted light for each pixel of CCDs(charge coupled devices) in a CCD camera 12, and frequency distributions of the number of times of appearance for each luminance are found out for all the pixels of the CCDs. The center of gravity in the frequency distributions is determined, and, by making a comparison of a value of the center of gravity, whether partial whitening crystallization is correctly performed is judged.  For example, by comparing a value of the center of gravity, which is thus determined, with the value in the case of a self-supporting container having a proper partial whitening crystallization region, which has been obtained in advance by the same method, it can be judged that whether the partial whitening crystallization is proper or not.

Abstract: PURPOSE: To reduce the irregularity of printing arising from a voltage drop at a  common electrode of a parallel drive type thermal head by making the common electrode thickner than individual electrodes, and to prevent the common electrode from abrasion by coating it with a protective film.  
     CONSTITUTION: A belt-shaped conductor 18 is provided on an end part of a  ceramic substrate 10, a belt-shaped thin film conductor 19 formed as one body with the individual electrodes 8 is provided on the conductor 18, and the common electrode 6 is made to be thicker than the individual electrodes 8, 9.

Since an abrasion-resisting film 20 which is provided over the heating resistors 4 and the individual electrodes 8, 9 for protecting them from abrasion due to contact with a heat-sensitive paper is extended 21 over the common electrode 6, the abrasion of the common electrode 6 and a rise in electrical resistance can be prevented.

Title: Deciding device for plane direction

IPC: B25J9/10
Filed: 1986-04-28
Abstract: PURPOSE:To decide the direction of a plane in a simple and accurate way by rotating a specific plane to undergo decision of its direction based on the distances between four points on said specific plane and a reference plane measured vertically to the specific plane. CONSTITUTION:A distance measuring device is provided to obtain the distance between those points A and B as well as C and D set on two straight lines M and N which are orthogonal to each other at a point O on a specific plane P and a plane Q measured vertically to the plane P from said four points. Then the distance between both points A and B and the plane Q are defined as (a) and (b) with a distance (m) defined between both points A and B respectively. Under such conditions, a rotational axis is set parallel to the line N around which the plane P can be rotated in the direction where both distances (a) and (b) are equal to each other at an angle alpha that defines (a-b)/m as a tangent. At the same time, another rotational axis is set in parallel to the line M round which the plane P can be rotated in the direction where both distances (c) and (d) are equal to each other at an angle beta that defines (c-d)/n as a tangent, where the distances between both points C and D and the plane Q are defined as (c) and (d) with a distance (n) defined between points C and D respectively. Thus the plane P is rotated round both rotational axes at angles alpha and beta.

Filed: 1988-04-21
Abstract: PURPOSE:To prevent copies taken by mistake by grasping image density information which is set automatically even at the time of automatic density mode by carrying out a density display of a manual density mode, equivalent to that density, even at the time of the automatic density mode selection. CONSTITUTION:The density of an original to be copied is read by an original density detecting means, concerning copying actions where the automatic density mode is set. Then based on the read original density, the most suitable image density for that original density is automatically judged from a ROM table, and the exposure condition and the developing condition are changed to change the image density. Even when the automatic density mode is selected here, a display of density judged based on the original density is displayed by a density display of a manual density mode equivalent to that density, that is the notch display by an LED 77 of a density display part 76. Thus a finished density can be assumed and grasped before the actual image formation, even at the time of the automatic density mode, preventing mistakenly taken copies.
