Patent JP-H0281646-A (JP)
Title: Thermal head
Inventor: SASAKI MASANARI
IPC: B41J2/345
Filed: 1988-09-20
Abstract: PURPOSE:To record a sharp medium contrast image without generating the deterioration of image quality largely by forming two or more kinds of heating resistors made different in a heat value or resistance value so that said resistors are respectively arranged in a combination arrangement predetermined at every predetermined arrangement unit. CONSTITUTION:The dot recorded by a heating resistor 11a is larger than the dot recorded by a heating resistor 10a. The same result is also obtained with respect to heating resistors 10b-10n and 11b-11n. That is, a thermal head constitutes a 2X1 matrix preliminarily and the sizes of the dots recorded at every pixel in the matrix are different and the driving part of this thermal head performs the control of driving using the matrix as one unit. Therefore, when dummy gradation recording is performed by this thermal head using the 2X1 matrix, three gradations and four gradations of 'dot-less' can be expressed. By this method, many gradations can be expressed by using a reduced number of dots and a medium contrast image can be recorded without lowering the resolving power too much.

Title: Front stopper for sheet fed printing machine
Inventor: FUNABASHI ISAO
IPC: B41F21/12
Filed: 1986-10-06
Abstract: PURPOSE:To reduce an occupied space for motion as well as to miniaturize a device, by pivotally supporting a stop holder, where a stop and a stop tongue are attached to the front end, and having this holder moved frontward and backward along a differential plate lower surface with a cam mechanism. CONSTITUTION:Since a rear end of a guide cam 47 becomes somewhat a down incline, paper 25 is held down by a stop tongue 56 as being slightly pushed back by a stop 55. Under this state, a swing shaft 72 is rotated and, after a swing gripper holds an end of the paper 25, the swing shaft is rotated in the reverse direction and simultaneously a cam follower 33 goes down on the down incline ranging from a large diametral part 28a to a small diametral part 28b of a cam 28. Therefore, the swing gripper grips the paper 25 and conveys it, while a stop holder 42 goes forward, and the stop 55 and the stop tongue 56 dodge from the paper 25 and they are retreated by each action of the guide cam 47 and a cam follower 51. And, when the cam 28 is further rotated, the cam follower 33 rises on a up incline of the cam 28 and reaches the large diametral part 28a whereby the stop holder 42 retreats and the stop 55 and the stop tongue 56 both go back.

Title: Image pickup device
Inventor: HIZUKA TETSUO
IPC: H04N5/335
Filed: 1984-11-12
Abstract: PURPOSE:To shorten image input time by inputting an output video signal from plural lines or area-like image pickup element to a frame memory simultaneously while switching said signal. CONSTITUTION:After the input order of a video signal from the 1st image pickup element 15 and a video signal 22 from the 2nd image pickup element 18 is adjusted by an input switching circuit 5, said signals are inputted to the frame memory 6 to obtain an image. Assuming that the magnification of a lens 11 is (m), the interval DELTAx of the image based on the video signals 21 and 22 goes to DELTAx=DELTAy/m. Where the drive frequency of the image pickup element and the image input time of one element are H and T, respectively, the drive frequency has to be 2H in order to set the image input time T to 1/2, because the image input time T is in inverse proportion to the drive frequency. However, the drive frequency has an upper limit, and therefore if plural image pickup elements are equipped, the image input time can be shortened without making the drive frequency larger.
