Title: Ink cartridge and ink jet cartridge
Inventor: ISHINAGA HIROYUKI
IPC: B41J2/175
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To increase the size and capacity of an ink cartridge without impairing its performance and reliability, by making the length of a negative- pressure-producing member between a communicating passage and an ink supply opening smaller than other lengths of the negative-pressure-producing member. SOLUTION: By giving a negative-pressure-producing member storage part 34 a notched shape, and also giving a negative-pressure-producing member 14 the same shape, a distance (d) between a communicating passage 20 and a supply opening 12 is made short, and between them and at an ink level 36b a sufficient width is given in an ink filled area indicating an upper boundary. That is, a short length and a sufficient cross-sectional area can decrease dynamic negative pressure and, therefore, increase the frequency response of an ink jet head and sufficiently cope with high-speed recording as well. An atmosphere- introducing groove 35 may be lower than the bent part of a partition 37 or as high as it, or higher than it.

Filed: 1987-10-30
Abstract: PURPOSE:To make good the hitting ratio of Al and to obtain an electrical sheet in the use of a hot rolled steel sheet having specific compsn. in which O amounts are regulated and limited amounts of Ti are added by subjecting the steel sheet to cold rolling in which intermediate annealing is interposed and to continuous annealing and finish annealing at a specific temp. CONSTITUTION:The steel consisting of, by weight, <=0.001% C, <=4.0% Si, <=1.5% Mn, <=0.2% P, <=0.015% Si, 0.003-0.015% SolAl, 0.0010-0.0100% N, 0.005-0.02% Ti and the balance constituted of Fe with inevitable impurities is subjected to hot rolling. The cold rolling for a one time or that for two or more times in which intermediate annealing is interposed is executed to form its final plate thickness. The steel is continuously annealed at 650-1,000 deg.C and is thereafter subjected to finish annealing at 800-950 deg.C to produce secondary recrystallization. If required, the hot rolled steel sheet is annealed at 700-1,000 deg.C before the cold rolling. By this method, the grain oriented electrical sheet having good iron loss and magnetic flux density can stably be manufactured.

Title: Viewfinder optical system for single-lens reflex camera
Inventor: SUZUKI MASAHARU
IPC: G03B13/26
Filed: 1987-10-30
Abstract: PURPOSE:To observe in an appropriate observing position and at a visual field magnification equivalent to a 35mm film size by adopting a secondary image- forming system for the viewfinder of a single-lens reflex camera and bending an optical path appropriately by reflecting it six times. CONSTITUTION:The title system is provided with two reflecting surfaces 6-a and 9-c which reciprocatingly reflect a viewfinder optical axis, three reflecting surfaces 9-b, 11, and 13 which are positioned on the optical axis of the viewfinder, and a secondary image-forming lens which is positioned on the optical axis and image-reforms a primary image formed by a photographing lens. Since there are two reflecting surfaces, surface 6-a and surface 9-c between the two reflections on movable mirror 2 and the surface 9-b and an even number of reflections, there is no inversion of images. Since mirrors 11 and 13 save the optical path enabling to observe in an appropriate position, a reflected luminous flux is observed facing the same direction vertically, and horizontally. By this method, an erecting image can be observed vertically and horizontally with an eye piece 14 and at the visual field magnification equivalent to that of the 35mm film size is obtained.

Title: Photomagnetic recording and reproducing device
Inventor: IWANAGA TOSHIAKI
IPC: G11B11/105
Filed: 1984-12-26
Abstract: PURPOSE:To stabilize information reproduction by adjusting a current which flows through the coil of a Faraday rotating element and setting the angle of rotation of the plane of polarization of reflected or transmitted light so that the S/N ratio of an information signal detected by a photodetector is maximum. CONSTITUTION:When a driving current is flowed from a coil driving circuit 13 to the coil 11 wound around the Faraday rotating element 10, a magnetic field is produced in the Faraday rotating element 10. The intensity of this magnetic field is varied by adjusting a current control resistance 12 and the current flowing through the coil 11 is therefore adjusted to rotate the plane of polarization of the reflected light from a beam splitter 4. The Faraday rotating element 10 rotates the plane of polarization of signal light and its angle of rotation is so set that the S/N ratio of the information signal detected by the photodetector 9 is maximum. Then, the same effect with the mechanical rotation of an analyzer 7 is obtained, the S/N ratio of a playback signal is easily maximized, and stable information reproduction is carried out.

Title: Magnetic tape reproducing device
Inventor: ARAI KAZUO
IPC: G11B15/467
Filed: 1989-10-24
Abstract: PURPOSE:To speed up control acquisition and to improve the stability by performing travel control by using a tracking error which is increased by an amplifier right after the start of a magnetic tape travel is commanded and using a tracking error which is not passed through the amplifier thereafter. CONSTITUTION:A memory 21 is stored with data corresponding to the difference between pilot signal amplitude voltages from both adjacent tracks reproduced by playback heads 2a and 2b. A multiplier 22 multiplies data, which is held in the memory 21 and outputted, by a specific coefficient and outputs the result. A controller 25 outputs indications for the travel and stop of a magnetic tape 1. When the controller 25 changes the command from the travel to the stop, a signal which is delayed behind a rotation command to a capstan motor 5a through a delay circuit 24 is outputted to a switch 26. The switch 26 transmits the output data of the multiplier 22 to an adder 12 until a travel command signal arrives from the circuit 24 and when the travel command signal arrives from the circuit 24, the output data of the memory 21 is sent to the adder 12. The output of this adder 12 is used to control the rotation of a motor 5a.

Title: Method for controlling sheet thickness in cold rolling mill of metal sheet
Inventor: TANAKA HAJIME
IPC: B21B1/28
Filed: 1988-11-02
Abstract: PURPOSE:To prevent breakdown of a rolled sheet in a succeeding stage by precisely tracking a welded point of a rolled base stock sheet and controlling the thickness of the welded point to be thicker than a standard sheet thickness in rolling the stock by a cold rolling mill. CONSTITUTION:A 1st stand feedforward AGC (speed control) 16 outputs a command increasing a sheet thickness of a welded point 2 by increasing a speed of a 1st stand motor 8 at arrival of the welded point 2 at a 1st stand 4. By that, a sheet thickness of the point 2 after passing the 1st stand 4 is increased. At arrival of the point 2 at a 1st stand sheet thickness gage 11, a signal is fed back to a 1st monitor 14 and the monitor 14 outputs a command to a 1st stand BISRA-AGC (draft control) 15 after processing the signal to bring a sheet thickness during rolling in the 1st stand to be reduced. After that, the same operations are performed so as to a 2nd stand and later stands. The sheet thickness increase formed in the 1st stand is kept until the final stand. Thus, sheet breakdown in succeeding stages is eliminated.
