Title: Grain oriented silicon steel sheet having high magnetic flux density and low iron loss and its production
Inventor: MASUI HIROAKI
IPC: C21D8/12
Filed: 1994-03-25
Abstract: PURPOSE:To produce a grain oriented silicon steel sheet capable of forming a primary film and also providing stable Goss-oriented secondary-recrystallized grains. CONSTITUTION:This steel sheet is a grain oriented silicon steel sheet having a composition where 0.001-0.50% of elements having >=70kcal/mol activation energy, such as Hf and Bi, are contained in iron containing 1-7% Si. The primary-recrystallized grain size of this sheet is regulated to 5-35mum, and the standard deviation value is 10-70% of the above. An antimony type compound is added by 0.05-5.0% to magnesia, and the average temp. rise rate from 800'C to the maximum ultimate temp. at the time of secondary recrystallization annealing is regulated to (0.1 to 80) deg.C/hr, and also the bearing between sheets at the time of secondary recrystallization annealing is regulated to <=0.3kg/mm<2>. At this time, when a boron type compound is used instead of antimony type compound, the temp. rise rate from 800 deg.C to the maximum ultimate temp. is regulated to (5 to 400) deg.C/hr. By this method, a magnetic flux density of >=1.92T can be stably obtained.

IPC: H04N5/238
Filed: 1990-03-09
Abstract: PURPOSE:To allow the device to pick up an image freely without caring about the lightness of surrounding by incorporating a light and applying lighting, extinguishing and dimming automatically. CONSTITUTION:A built-in light 11 is incorporated in a case of an electronic view finder 10 and the case is so structured that the radiating face is not exposed to the surface of the case when the built-in light 11 is not in use.

Title: Roll device for giving specular surface to magnetic recording medium
Inventor: YAMASHITA SADAO
IPC: G11B5/84
Filed: 1985-03-20
Abstract: PURPOSE:To improve the electromagnetic conversion characteristic of a magnetic recording medium and to prevent drop-out by forming a Japanese lacquer coating film on the surface of an elastic roll in a roll device for giving a specular surface to the magnetic recording medium which forms a magnetic layer to a specular surface. CONSTITUTION:A magnetic recording medium 1 where the magnetic layer is formed on a nonmagnetic supporting body consisting of a polyester film or the like is fed out of a supply roll 2 and passes between an upper metallic roll 3 and an elastic roll 4 and between the elastic roll 4 and a lower metallic roll 5 and is wound up around a take-up roll 6. The elastic roll 4 is obtained by forming a Japanese lacquer coating film 4b on the outside peripheral surface of a metallic roll body 4a, and a roll pressurizing surface is formed by this coating film 4b. Since the hardness of the elastic roll 4 is raised, the roll surface is finished to a sufficient specular surface, and the magnetic recording medium having the specular surface is obtained to improve the electromagnetic conver sion characteristic. Further, drop-out due to flaws on the surface of the magnetic layer is prevented.

Title: Composite sail
Inventor: NARITA HITOSHI
IPC: B63H9/06
Filed: 1983-03-31
Abstract: PURPOSE:To utilize a wind power to its maximum, by permitting air to flow on back sides of a sub hard sail and a soft sail and thereby to prevent separation of an air layer on the back sides. CONSTITUTION:A clearance 7 is defined between a rear end portion of a main hard sail 1 and a front end portion of a sub hard sail 8, so as to create air flow B on back sides of the sub hard sail 8 and a soft sail 9. A part of air flow is leaked from the clearance 7 to flow on the back sides of the sub hard sail 8 and the soft sail 9. In other words, a hard sail is divided into the main hard sail 1 and the sub hard sail 8, and the vertically extending clearance 7 is defined between both the hard sails 1 and 8, so as to permit a part of air to flow on the back sides of the sub hard sail 8 and the soft sail 9. With this arrangement, turbulence of air flow on the back side of the composite sail may be prevented, and a wind power may be effectively converted to a propelling power.

Title: Horizontal automatic ink delivery device
Inventor: KONDO TOSHIHIRO
IPC: G01C15/00
Filed: 1985-03-20
Abstract: PURPOSE:To make it possible to always project laser beam to a horizontal direction, by mounting a reflective mirrors on the suspension plates suspended from the ceiling surface of a container by two pairs of suspension systems and reflecting laser beam from a light projector to a horizontal direction by said reflective mirrors. CONSTITUTION:Projection lines of suspension lines 10a, 10b and 10b, 10c of one of each pair among two pairs of suspension lines are respectively superposed and become left and right symmetric. The projection lines intersect at the upper parts thereof and the width Z of mount points to the ceiling surface 2a of the suspension lines is set so as to be extremely small as compared with the width (y) of mount points to a suspension plate 8. By this method, even when a con tainer 2 is inclined by about 0-10 deg., the suspension plate 8 is held to an almost horizontal direction. Therefore, the inclination of a reflective mirror 6 to that of the container in this plane does not change and laser beam L1 is always emitted horizontally.

IPC: G03B13/34
Filed: 1992-02-08
Abstract: PURPOSE:To increase the effective set number of steps of a step motor driving type lens driving mechanism while keeping working accuracy. CONSTITUTION:When a pinion 12 is turned right to make an adjusting member travel right, a cam member 4 is extended by 1/3 step toward an object by step cams 4g-4i for fine adjustment. When the pinion 12 is turned left to make the cam member 4 travel left after the relative position of the adjusting member to the cam member 4 is fixed by a ratchet 8, a lens group 1 is extended by one step toward the object by the step cams 4a-4f for rough adjustment. Namely, since the stroke of the step cams 4a-4f is subdivided by the step cams 4g-4i, the effective set number of steps of the lens group 1 is shown as the arithmetic product of the set number of steps of the cam for rough adjustment and the set number of steps of the cam for fine adjustment, and the effective set number of steps is drastically increased.

Title: Data writing control method to magnetic tape recording device
Inventor: SAKASHITA KAZUYUKI
IPC: G11B5/09
Filed: 1978-05-15
Abstract: PURPOSE: To always ensure an accurate data writing by repeating the rewriting in the fixed times when the data writing is abnormal and also carrying out the error process whrn the normal writing is not secured.  
     CONSTITUTION: When the data is written into magnetic tape recorder 2 from cash register main body 1, the block data is transmitted following the counting data with retransmission counter 7 and retransmission/rereception counter 13 feature zero. Thus, the counting data is memorized in counting data memory 12, and the counting data are compared at comparator 14 between counter 7 and counter 13. As the value of the both counters are zero and identical to each other, the block data is written onto magnetic tape 18. In the case of the normal writing, affirmative signal ACK is delivered to clear counter 7 and 13. In case the writing is abnormal or no coincidence is obtained through comparison at comparator 14, negative signal NACK is delivered to count up counter 7 and 13 by one. Thus, the data is transmitted again from main body 1. And the error process is carried out when the retransmission frequency reaches the fixed level.
