Title: Rotary head type magnetic picture recording and reproducing device
Inventor: FUKAI TOSHIHIKO
IPC: H04N5/7826
Filed: 1985-05-02
Abstract: PURPOSE:To perform direct recording without any intervention of an image delay circuit and further eliminate the distortion of an image surface during reproduction by providing a couple of rotary recording heads which have a mutual step, a couple of rotary playback heads which have no step, and a device which drives a tape intermittently. CONSTITUTION:An L head 13 for recording and an R head 14 for recording are fitted in a pair to the rotary part of a rotary cylinder 8 at an interval of 180 deg. while having the mutual step l and trace different surfaces through the rotation of the cylinder. An L head 15 for reproduction and an R head 16 for reproduction have no step and trace the same surface. A tape speed has three periods, i.e. acceleration period, constant-speed period, and deceleration period and a recording current is flowed to the two L and R rotary heads in the constant-speed period to record one frame. Tape feed in which recording is not performed in the acceleration and deceleration period is absorbed by the step of the heads to obtain the same head track as that of continuous reproduction, and its playback output waveform has a constant horizontal synchronizing signal period, so that no distortion appears in an image surface.

Title: Protection of print head in ink jet printer
Inventor: KAWAI MASATADA
IPC: B41J2/165
Filed: 1981-06-18
Abstract: PURPOSE:To prevent the generation of air bubbles in a print head or the breakdown of a strain gauge, even when not in use for a long period of time, by filling the print head with a protection liquid in place of ink. CONSTITUTION:When an ink jet printer is not in operation or a print head is not attached to the printer, a common ink chamber 3 and pressure chambers 4a, 4b...4l in the print head are filled with a protection liquid in place of ink. The preferable kind of the protection liquid is polyhydric alcohols, e.g., ethylene glycol. Since these polyhydric alcohols have hydroscopic property, low-vapor pressures, and thickening property, the permeability to the flexible thin films (a) and 14 is very small, and therefore, the evaporation of the liquid does not occur almost from nozzles 6a...6l, no breakdown of strain gauges 11 and 12 occurs, and no bubbles are generated in the print head.

Title: Light beam splitting method and light beam splitting and modulating method
Inventor: TANIURA HIROSHI
IPC: G02F1/11
Filed: 1988-04-18
Abstract: PURPOSE:To make a beam splitting number twice as large as before by entering light beams of uniform intensity incident at a required angle into a light beam splitter which has a total reflecting film provided on one surface of a light transmitting material partially in a beltlike shape and a 50% reflecting film on the other parallel surface partially in a beltlike shape. CONSTITUTION:The light beam splitter 9 has the total reflecting film 9b formed by coating one surface of the light transmitting material 9a partially in the beltlike shape and also has the 50% reflecting film 9c formed by coating the other surface partially in the beltlike shape in parallel to the surface coated with the total reflecting film 9b. This 50% reflecting film 9c transmits the eight light beams which are incident under the total reflecting film 9b and travel in side by a half in quantity and reflects the remaining half of the light beams to the total reflecting film 9b. The light beams which travel in the light transmitting material 9a toward the total reflecting film 9b are reflected by the total reflecting film 9b and transmitted above the 90% reflecting film 9c on the opposite side. Thus, the light beams are split into upper and lower parts, which are projected.

Abstract: PURPOSE:To attain excellent recording and reproduction by adopting the single layer structure of a ferromagnetic metallic material for a front gap of a lower magnetic substance layer and an upper magnetic substance layer and separating the ferromagnetic metallic material at an interval twice or below the surface depth. CONSTITUTION:A lower magnetic substance layer 9 of a thin film magnetic head is made of a material such as 'Sendust(R)', 'Permalloy(R)' or Co group amorphous magnetic metallic layer, and the multi-layer film laminated structure is adopted to parts other than a front gap 9a and a back gap 9b, where many insulation layers 11, 11 made of SiO2 or the like are formed at an interval (m) twice or below the the surface depth delta at the upper limit frequency of the recording/reproducing signal flowing to a conductor coil layer 4.
