Title: Detector for density of picture image
Inventor: TOMITA MASAMI
IPC: G03G15/00
Filed: 1982-04-01
Abstract: PURPOSE:To enable the exact detection of the density of a picture image while preventing sticking of a toner on a sensor which detects the density of the toner image on a photoreceptor by disposing an outside frame having a photodetection window around the sensor. CONSTITUTION:A detector 1 for the density of a picture image which detects the density of the picture image on a photosensitive drum 3 developed to a sensible image by a developing device 2 optically is disposed in proximity to the device 2 and the drum 3. The detector 1 has a sensor 5 which draw out the electric signal corresponding to the quantity of light of the toner image formed on the drum 3, and a photodetection window right above the sensor 5 as well as an outside frame 6 which is so formed and disposed as to enclose the entire part of the sensor 5; therefore, the scattering of the toner from the frame 6 to the inside is prevented effectively, and the sensor 5 is opeated normally for a long period of time.

Title: Device for stable threading of slit strip
Inventor: IIDA HIDENORI
IPC: B21C47/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To improve threadability by providing pinch rolls capable of effecting one side reduction between a slitter and a tension reel, controlling the rolling force of pinch rolls on the drive side and the work side, and straightening the strip in the direction of keeping the strip apart from the center line. SOLUTION: Pinch rolls 7 nondriven and capable of adjusting one side reduction are provided on the outlet side of a slitter 2. At the time of threading, only the vicinity of a center part of a steel sheet 5 of the work side WS is subjected to reduction, and a tensile strength distribution δ (x) due to frictional force between the steel strip 5 and the pinch roll 7 is generated; thereby, giving a clockwise angular moment M on the strip 5, the strip is moved from the line-center to the work side WS. Further, the amount of correction of deviation between the line-center and the strip 5 is controlled through the optimum adjustment of rolling force on the strip 5 by the pinch roll 7 capable of adjusting one side reduction.

Title: Cut part shape recognizing method for metal sheet parts developed model
Inventor: MIZOGAMI TAKAHIRO
IPC: G05B19/4155
Filed: 1993-02-17
Abstract: PURPOSE:To automatically recognize the shape of a cut part by generating the two-dimensionally developed data of each segment from the developed model, extracting the developed data having only one of its both ends set on a basic line, and then extracting a series of developed data groups connected together in a chain to group these data groups as the component data on a single cut part. CONSTITUTION:The developed data are generated in a step 1 according to a developed model, and the maximum and minimum values are calculated for X and Y coordinates in a step 2 according to the coordinates of both ends of the line and arc elements, respectively. In a step 3, the developed data on the line element set on the basic line is excluded out of the retrieving subjects among all developed data. Then, the developed data having one of its both ends set on the basic line is retrieved in a step 4. A point set on the basic line is defined as a group start point for the developed data detected in a step 6, and a series of developed data groups connected together in a chain are extracted out of the group start point. These developed data are grouped and excluded out of the retrieving subjects.

Title: Thermal printer
Inventor: FUNADA KUNIHIKO
IPC: B41J29/13
Filed: 1990-03-05
Abstract: PURPOSE:To miniaturize an apparatus by installing a photosensor used both for detecting a medium mark and for detecting a head-up state in the position of facing a printing medium approach path in the bridge part of a head-up lever for retreating a thermal head from a platen. CONSTITUTION:Because a photosensor S is installed in the position of facing a printing medium approach path 6 of a bridge part 11, it can detect whether or not there are a printing paper and printing paper mark. Also, because the photosensor S is installed at the bridge part 11 formed into an integral body with a rotating head-up lever 5, the photosensor S of the bridge part goes toward the outside of the device and a detection light reflects externally of the device when the head-up lever 5 is operated for setting paper, etc., to push up the thermal head from the platen to make it retreat. Consequently, the detection light cannot reflect to enter the photosensor S so that detection becomes impossible. When the head-up lever 5 is operated and the photosensor S cannot function, it is possible to recognize that printing is impossible.

IPC: G11B15/26
Filed: 1994-02-25
Abstract: PURPOSE:To reduce the generation of noise by smoothly engaging an intermediate gear with a reel gear without increasing the pushing amount of a control lever. CONSTITUTION:In the midst of the pushing of the control lever 1 from the non-working position to the working position, the rotation of a flywheel 23 is temporarily stopped by making the engaging parts 17,62 of movement members 10,63 engage with a fitting part 22 which is integrally rotated with the flywheel 23. At this time the rotation is stopped, the intermediate gear 30 is moved to the position to be engaged with the reel gear 40 to make the intermediate gear 30 engage with the reel gear 40. Subsequently, when the control lever 1 is further pushed to the working position, the engaging parts 17,62 are disengaged from the fitting part 22 to allow the rotation of the flywheel 23. Then, the rotation of the flywheel is restarted, so the intermediate gear 30 is also rotated, and the rotation of the reel gear 40 is started since this intermediate gear is already engaged with the reel gear 40.

Abstract: PURPOSE: To reduce the excessive power consumption to the least, in the LSI, by constituting the unit that the clock signal is not operated unless the key trailing signal is incoming even if the key is kept depressed, after the end of operation process.  
     CONSTITUTION: In the clock control section CC, the system clock signal (outputs ϕ 1  to ϕ 3  of NOR gates OG 1  to OG 3 ) is produced together with the start of key depression and release of key depression, and the system clock signal is stopped with the halt instruction of the system clock signal caused from ROM at the end of operation (B)(in micro order). Accordingly, the control signal S supplies the system clock signal to the operation control means with the trailing signal of the key input  (where: f k  is the leading and trailing signal of key input) and the instruction (B) stops the supply to the operation control means (clock halt period), allowing to avoid the operation of the system clock signal unless the trailing signal is incoming with the key input, even if the key is remained depressed.
