Title: Optical fiber aligning body
Inventor: KASHIWAZAKI AKIRA
IPC: G02B6/24
Filed: 1994-08-09
Abstract: PURPOSE:To form an optical fiber aligning body by an easy and practical means by making the width of a fixing substrate smaller than that of an aligned substrate with formed guide grooves, but making the width of the substrate large enough for covering the whole area with the guide grooves in the aligned substrate. CONSTITUTION:Optical fiber positioning V-shaped grooves 41 are formed on the upper surface 24 of the aligned substrate 21 for arraying an optical fiber. Optical fibers 31 to 34 are separately installed in respective V-shaped grooves 41. The upper surface is covered with a rectangular fixing substrate 11 for pressing the optical fibers. The width of the fixing substrate 11 is made smaller than the width of the aligned substrate 21, then, the side face 12 of the fixing substrate 11 is not aligned with the side face 22 of the aligned substrate 21, and the side face 12 is positioned on the upper surface 24 of the aligned substrate. Besides, the width of the fixing substrate 11 is made larger than the area where the V-shaped grooves 41 for installing the optical fibers are formed so as not to constitute an obstacle to fix the optical fibers. That is, the width of the substrate is made larger than a distance between the optical fibers 31 and 34 installed at both ends.

Abstract: PURPOSE:To obtain a function which executes recording and reproducing at the same time and which has low crosstalk, low noise and low cost by making a reproducing amplifier corresponding to a head which is used for recording among adjacent plural heads inactive at the time of recording. CONSTITUTION:A signal recorded by using one among the heads for standard and special reproducing consisting of adjacent two heads 4a and 5b, 4b and 5a is recorded and reproduced at the same time by heads for simultaneous reproducing 6a and 6b. Besides, the amplifiers for amplifying signals reproduced by the respective heads 6a and 6b are loaded on a rotating cylinder. Then, the recorded signal and the reproduced signal amplified by the amplifier are simultaneously transmitted by a rotary transformer 26. Simultaneously the amplifier corresponding to the head for special reproducing which is adjacent to the recording head is controlled so as to be turned off at the recording time. Besides, the amplifier corresponding to the heads for simultaneous reproducing 6a and 6b is controlled so as to be turned off at the normal reproducing time. Thus, even when the heads are arranged so as to obtain the excellent interchangeable reproducing, the problem of the crosstalk between adjacent channels is solved and the function which executes the recording and the reproducing at the same time and which has the low noise and the low cost and the special reproducing function are obtained.

Abstract: PURPOSE:To improve stbility of operation in a coal gasifying oven in which a condensation/fluidization type gasifying oven is connected to a jet stream combustion chamber by use of a grateless throat, by shifting a burner nozzle of the combustion chamber to a specified horizontal angle against the axis of the combustion chamber. CONSTITUTION:In a coal gasifying oven, an upper condensation/fluidization gasifying oven 3 is connected to a lower jet stream combustion chamber 4 by use of a grateless throat 2 and a burner nozzle 1 of the combustion chamber 4 is shifted to a predetermined angle smaller than 10 deg. against the axis of the combustion chamber 4. A part of produced gas is introduced into the chamber through the nozzle 1 and is burned. The produced combustion gas is whirled and led into the gasifying oven 3 as fluidized gas to cause gasification reaction of dust coal in the gasifying oven 3. Thus, condensed ash formed in the gasification reaction falls through the combustion chamber 4 and is discharged efficiently, leading to a reduced amount of char that falls through the throat 2.

Filed: 1990-07-16
Abstract: PURPOSE:To increase the mounting density on a printed-circuit board even if the package has a smaller lead spacing by arranging outwardly bent leads and inwardly bent leads alternately on the package sides to avoid contact of adjacent leads. CONSTITUTION:A semiconductor package 10 has outwardly bent leads 12 and inwardly bent leads 13 on its sides; the leads 12 and 13 are alternately arranged.

Title: Occupant crash protector
Inventor: IKEGAMI KENJI
IPC: B60R21/16
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To select and control the inflation mode of an airbag exactly by estimating an occupant position at the time of starting inflation of the airbag at a high speed without need for an occupant position sensor with high-speed responsiveness. SOLUTION: When a G sensor 11 for detecting pre-crash braking detects the pre-crash braking, the seating position of an occupant detected by an occupant position detector 3 until that time is obtained. The occupant position of the occupant is estimated at the time of starting to inflate the airbag based on the seating position of the occupant before crash occurs and an occupant traveling distance computed by secondary order time integral computation of acceleration detected by a crash detecting G sensor 11 against an impact caused by the crash. The airbag is inflated in a normal mode when the existing estimated position of the occupant is out of a prescribed distance range from a jumping opening of the airbag. When the existing estimated position of the occupant is within the prescribed distance range from the jumping opening of the airbag, it is inflated in a moderate inflating mode.

IPC: F24F7/06
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a range hood device in which its cleaning work becomes quite easy and its working efficiency can be improved. SOLUTION: Since an inner hood 18 covers an inside part of a main body 15 of a range hood except a communicating port 20, oil adheres only to the inner all of the inner hood and no adhesion of oil occurs at the inside part of the main body 15 of the range hood, resulting in that area to be leaned is restricted and its cleaning work is facilitated. Further, since the inner hood 18 can be oscillated about a pivoting part 21 of a front end of a smoke collecting port 16, a cleaning worker can clean efficiently only the inner hood in an easy posture.
