Title: Hydrogen chloride absorbing device and absorbing method
Inventor: TSUMURA HIROSHI
IPC: B01D53/18
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent a gas supply pipe to a column and a peripheral part thereof from becoming corroded and thereby enable a device to be operated continuously for a long time by fitting a tantalum sleeve to the inner wall of the gas supply pipe on the column with a water spray means having water spray holes installed at the internal upper part and the gas supply pipe installed at the lower part. SOLUTION: A water spray device 3 is installed at the inner upper part of a column 1. In a gas supply pipe 5, a water supply pipe 7 made of tantalum with a spray nozzle 8 or the like fitted at the tip, is installed. A dry gas containing hydrogen chloride is supplied to the gas supply pipe 5 and then is supplied into an absorption column 1 while the gas is cooled by water sprayed from the spray nozzle 8 after being fed from the water supply pipe 7. In this case, a tantalum sleeve 6 is mounted in the gas supply pipe 5 so that the corrosion of a material for piping is inhibited and at the same time, the gas supply pipe 5 is protected against a hot gas. After this procedure, the gas is brought into counter-contact with the spray in the absorption column 1 to cool/absorb the gas.  On the other hand, the water absorbing the hydrogen chloride is unloaded from a line 10 and then is circulated for use.

Title: Optical system recording and reproduction device
Inventor: KANEHIRA ATSUSHI
IPC: G11B7/005
Filed: 1991-10-24
Abstract: PURPOSE:To detect the moving amount of a lens and to change the detection starting position so as to stably and accurately reproduce the multi-valued recording due to the change of intervals of a pair of pits in the track width direction while correcting the outer disturbance such as the inclination of the pattern. CONSTITUTION:The laser beam absorbed by an objective lens 3 is irradiated to multiple pits arranged in the track width direction. A linear array detecting device 4 detects an interference pattern 5 which is obtained from the multiple pits to reproduce the information. The shift amount of the objective lens 3 is obtained by compensating the phase of a lens actuator tracking driving signal 9. The detection start position of a linear array detecting device 4 is changed by A/D-converting this shift amount and performing transfer with the transfer starting address of a transfer shift register 12 deviated by a transfer starting address specification ROM 13.

Abstract: PURPOSE:To prevent effectively a photosensitive body from being fatigued by controlling the driving of the photosensitive body for an electrophotographic method so that the rotating speed in preliminary rotation which is carried out prior to image formation is faster than the rotating speed during in image formation. CONSTITUTION:The driving of the photosensitive body 1 for the electrophotographic method is so controlled that the rotating speed in the preliminary rotation which is carried out prior to the image formation is faster than the rotating speed in the image formation.

Title: Head spring for facsimile
Inventor: OKA MASAHARU
IPC: H04N1/032
Filed: 1993-10-08
Abstract: PURPOSE:To evenly press a thermal head and to secure the even print density by pressing the thermal head at four points by means of two head springs having the asymmetrical elastic forces. CONSTITUTION:A head spring 1 consists of outer and inner elastic metallic pieces 4 and 5. The piece 5 has the elastic force smaller than that of the piece 4 owing to a cut part 7. The top plates 2 are screwed and fixed into an upper chassis 10 by the screw 8 with the projection parts 6 of the head springs 1 kept in the projection holes 12 respectively. Therefore both pieces 5 are set internally opposite to each other together with the pieces 4 re set externally opposite to each other. Under such conditions, these pieces are fixed. In such a constitution, the even pressing force is secured at each part of a thermal head since the elastic force of the piece 5 is set less than the piece 4.

Title: Magnetic head feeding mechanism
Inventor: IGARI MITSUO
IPC: G11B21/02
Filed: 1989-10-27
Abstract: PURPOSE:To make a colliding sound small when a carriage is moved by enlarging the thrust pressure of a step motor with the inertia force of the carriage and the frictional force of a sliding part. CONSTITUTION:When a roller 12 is rotated integrally with the screw shaft 7 of a stepping motor 5, a carriage 1 through a linking part 9 executes linear motion and a head 3 is positioned at an objective track. At this time, since the inertia force of the carriage 1 and the frictional force of a guide shaft 2 part, etc., are present thereon, a roller 12 activates the force in a direction reverse to the moving direction of the carriage 1 and tries to generate a gap between a screw shaft tip part 8 and a screw shaft tip receiving part 13. In such a case, the thrust pressure caused by a thrust pressing means 11 is made larger than the inertia force of the carriage 1 and the frictional force of the slide part 9. Accordingly, the gap is not generated between the screw shaft tip part 8 and the screw shaft tip receiving part 13. Thus, without generating the collision sound, the carriage can be moved with low noise.

Abstract: PURPOSE:To generate a diode function having excellent characteristics by a base region in a transistor and an epitaxial layer by forming a buried region to a semiconductor substrate, growing the epitaxial layer onto the whole surface containing the buried region, changing the epitaxial layer into a completely insular region by an annular contact region being in contact with the buried region and shaping the transistor into the insular region. CONSTITUTION:An n<+> type buried region 4 is diffused and formed to the surface layer section of a p-type Si substrate 1, an n<-> type layer 2 is grown on the whole surface containing the buried region in an epitaxial manner, and the layer 2 is isolated by a p<+> type region 3 reaching the substrate 1. An annular n<+> type contact region 6' extending up to the surface of the layer 2 is diffused and shaped to the peripheral section of the region 4, and the isolated layer 2 is converted into a completely insular shape. A p-type base region 5, an n<+> type emitter region 7 and a p-type region 21 being in contact with the inside of the region 6' are formed to the insular region, thus constituting an npn transistor by the layer 2 and the regions 5 and 7. Accordingly, a diode function is generated simultaneously by the region 5 and the layer 2, thus acquiring an IC containing a diode having excellent forward characteristics and reverse withstanding-voltage characteristics even in a large current region.
