Title: Production of composite type floating magnetic head
Inventor: KITSUNAI TSUNEYUKI
IPC: G11B5/60
Filed: 1989-04-25
Abstract: PURPOSE:To prevent the chipping near the slit groove of the rear surface of a slider by simultaneously welding and contact surface side with a magnetic recording medium and a rear surface side by using glasses which are the same in m. p. and coefft. of thermal expansion at the time of welding the slider an a magnetic core chip. CONSTITUTION:The magnetic core chip 2 which is previously formed with a gap and is packed with the glass 3 for welding on the contact surface side 9 with the magnetic recording medium is inserted into the slit groove 4 of the slider 1. A glass rod 3a which is the same in the m. p. and the coefft. of thermal expansion as the glass 3 for welding packed to the contact surface side 9 with the magnetic recording medium is then set on a base 8 of a chip winding hole 5 of the magnetic core. The setting of the glass rod 3a for welding is stabilized by previously forming the base 8 of the winding hole 5 to such a size and shape that the base 7 of the winding groove 6 of the slider is higher than the above-mentioned base at this time. The glasses 3, 3a for welding are then heated up to the m. p. and melted in an inert atmosphere, by which the contact surface side 9 with the magnetic recording medium and the rear surface side 10 are simultaneously fixed. The chipping near the slit groove 4 on the rear surface of the slider and the rear surface side 10 of the magnetic core chip 2a which are brittle materials is prevented in this way.

Abstract: PURPOSE: To select a printing speed and image quality in accordance with request by changing the number of the colors of toner used for developing in a single action with one rotation of recording bodies and their speeds, linked with the number of the colors of toner. CONSTITUTION: When a complete full color image is desired, a printing operation is switched to a full color mode operation, that is, two-color simultaneous printing by first and second recording bodies 11 and 21 is switched to printing in each color by one rotation of the respective recording bodies. In the first rotation of the first and second recording bodies 11 and 21, the printing with cyan toner 141 and yellow toner 241 is attained so that they are superimposed to form a two-color toner image on an intermediate transfer body 3. In the second rotation of the first and second recording bodies 11 and 21, the printing with magenta toner 151 and black toner 251 is attained so that they are transferred to the intermediate transfer body 3, to be superimposed on the first formed two-color toner image of cyan and yellow, to form a full color image.  Then, the full color image is transferred to a recording paper 4 by a transfer unit 32 and thermally fixed by a fixing unit 5.

Filed: 1989-04-25
Abstract: PURPOSE:To sufficiently secure the amount of cold water that is decreased by the opening of external faucets by a method wherein the circulation of cold water between a water tank and an outer tank provided therein with an evaporator is stopped in accordance with a temperature detection signal when the water level in the water tank is at a lower level or above and the external faucets are opened. CONSTITUTION:The level of cold water in a water tank 20 is at the position of a water level sensor 80, and water in an outer tank 20a is cooled by an evaporator 40 provided in a freezing cycle. When the water level is lowered down to the position of a water level sensor 90 by opening external faucets FC, a water feed valve Wv is opened to supply water, and external and internal circulating pumps Po, Pia, Pib are operated to allow water to circulate between the water tank 20 and the outer tank 20a. Furthermore, when a cold-water temperature in the inner tank 20 becomes high, a compressor 50 is driven by means of a thermostat switch Th, and simultaneously, the circulating pumps Po, Pia, Pib are operated. However, in a state that the water level is not lowered down to the position of the water level sensor 90 while the external faucets FC are opened, the operations of the circulating pumps are stopped, and a decrease in the amount of cold water by the opening of the external faucets FC is prevented. Thus, the sufficient amount of cold water can be secured.

Title: Sheet member vibration isolator
Inventor: SUGITA YASUTOSHI
IPC: B65H23/02
Filed: 1982-06-22
Abstract: PURPOSE:To count frame marks accurately, by providing a vibration isolator having a couple of flanks which spreads out toward lower sides like an inverse unfolded fan and have the lower sides at a distance less than the width of a sheet member such as a microfilm. CONSTITUTION:The microfilm F is drawn by a take-up reel and conveyed between the upper side 11d and lower side 11E of the flank 11a of the vibration isolator 11, and a retrieval device detects a necessary frame number and outputs a stop signal. Then, a film take-up motor is turned off and at the same time, fine vibration in the conveyance direction of the microfilm F is generated. However, the tension of the microfilm F is relieved simultaneously with the generation of the vibration and the microfilm F sags to bring both its ends Fe into contact with an internal surface 11G; and the resulting frictional force absorbs the oscillation in the conveyance direction of the microfilm F to eliminate an error of frame mark counting.
