Title: Laser diode
Inventor: TANAKA HARUO
IPC: H01S5/042
Filed: 1989-09-13
Abstract: PURPOSE:To obtain an output of a constant level, stabilizing the temperatures of laser diodes by providing plural independent light emission parts close to each other and operating only one part of them while stopping the light emissions of the other parts. CONSTITUTION:Two independent light emission parts, diodes LD1, LD2, are provided so close to each other as to be coupled thermally to each other. When operating, only one of the diodes LD1, LD2 emits laser light and another one stops its emission. Since the diode LD1 and diode LD2 emits light alternately and successively after starting their operations, the temperature of a diode unit 10 is stabilized at a constant value immediately and the temperatures of the diodes LD1, LD2 in operation become constant. Thereby, an output system can keep its output at a constant level by itself without necessity of performing an uncertain prediction control and the like.

Title: Manufacture of ink jet head
Inventor: KIKAWA KEISUKE
IPC: B41J2/16
Filed: 1992-08-14
Abstract: PURPOSE:To provide an ink jet head that is free from cracks, breakage and deformation caused by mechanical working strain during manufacturing, and is capable of executing high quality printing. CONSTITUTION:The surface to which grooves forming ink chambers 8 for a piezoelectric body are to be machined is coated with resist film 2. Then, the grooves are machined and electrode film 4 is attached thereto. The electrode film over the resist film 2 is then removed chemically together with the resist film by lifting-off method, leaving the electrode film only to the inside of the grooves of the ink chambers. Since surplus electrodes are removed chemically, mechanical working strain is not left over to the piezoelectric body 1. Furthermore, adhesive does not protrude into the ink chambers because no cracks nor breakage are produced during machining.

Title: Facsimile equipment with space attaching function
Inventor: TAKAHASHI MUTSUAKI
IPC: H04N1/387
Filed: 1989-09-13
Abstract: PURPOSE:To easily perform the arrangement of reception paper by thinning a prescribed number of bits from reception data of one line, and attaching white bits equivalent to the thinned number of bits on the terminal part of thinned data of one line. CONSTITUTION:Decoded bit data of one line is stored in an image memory 7, and reduction is performed at a reduction circuit 6 by thinning the bit at a prescribed interval. At this time, since a lengthy image is generated by applying reduction only in a width direction, it is enough to perform the reduction with the same ratio also in a longitudinal direction at right angles to a scanning line to evade such state. In other words, it is enough to perform one line of thinning at every eleventh line. Therefore, an image 31 can be reduced as a whole, and it goes to an image 32. In such a way, a space can be provided at the left side of a reduced image 32, and also, spaces 34, 35 are attached on the upper and lower sides of the image, which facilitates the arrangement of the reception paper.

A signal S2 is inputted from a head position controlling part 12, and the ordinate of the reception position of the printing head relative to the paper is counted. When the paper is fed to the top margin setting position, a setting key 102 is depressed, whereby a value held by a counter 13 is stored into a control data storage part 16 as a reception position of the printing head for setting a top margin. Similarly, a reception position of the head for setting a bottom margin is also stored into the storage part 16. Accordingly, the control data for the top and bottom margin setting positions can be stored for each kind of paper.

Abstract: PURPOSE:To prevent the rotating side unit of a rotary cylinder device for video tape recorder, etc. from coming off, by securing a pin to a lower cylinder so that it is positioned within 1mm. above a rotary disc. CONSTITUTION:When a motor is driven, a rotating section unit 35 is rotated, an electrical signal taken out by means of a head 26 is led to the outside through rotary transducers 27, 32. In order to prevent the rotating section unit 35 from coming off, a pin 31 is inserted and secured into a transverse hole 21B in a lower cylinder 21 so that the distance between the pin 31 and a disc 23 is made sufficiently small, that is made less than 1mm.. With this arrangement, a C ring conventionally used is made unnecessary so that the distance between grooves 22A, 22B for producing the dynamic pressure of radial bearing may be made large, thereby there may be provided a fluid bearing which is excellent in angular rigidity. Further, the assembling ability of the bearing may be enhanced.
