Filed: 1993-09-21
Abstract: PURPOSE:To provide an apparatus for incineration and a related method for the disposal of all waste matter by incineration without causing environmental polution which are designed not to discharge the products of the operation to the outside but to confine their disposal within the same apparatus. CONSTITUTION:An incineration furnace 2. having a lid 10 which opens upward, is heated to high temperatures by burners 11, 12 and with supply of water and discharge liquid and effects complete combustion of waste matter.

IPC: G01D5/38
Filed: 1990-09-26
Abstract: PURPOSE:To improve the reliability and accuracy of a device by providing a member having the index of refraction larger than that of the air in the optical path inside a cylindrical scale. CONSTITUTION:In an optical path between a first area 31 and a second area 32 of this system is inserted an optical transmission member 200 having the index of refraction larger than that of the air (n0=1) (n being the index of refraction). Accordingly, the position where a Fourier image is formed is moved and the Fourier image of higher contrast can be formed in the second area 32. In other words, since the parallel glass plate 200 of the thickness (d) is inserted, a sixth image is eventually separated from the grating surface, and a fourth image is moved to be formed at the position of the grating part of the second area 32. Since the fourth image (N=4) of higher contrast than the sixth image (N=6) is used, the S/N of the detecting signal is enhanced and the detecting reliability is improved.

Filed: 1988-10-12
Abstract: PURPOSE:To elongate the luminous time of a flash lamp by applying discharged outputs of several supply sections successively to the same flash lamp within a time interval needing no retriggering.

Title: Ball bearing
Inventor: HISHIDA TADASHI
IPC: F16C33/58
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To increase load capacity and reduce run out of an outer ring at the time of revolution of a bearing by forming the raceway grooves of outer/ inner rings into cross section V shapes having tapered surfaces inclining in the opposite directions on both the sides. SOLUTION: Each raceway grooves 2 and 4 of each of outer/inner rings 1 and 3 comes into contact with a ball 5 at two points and receives load at each contact point when load is applied to a ball bearing by forming the raceway groove 4 of the outer ring 1 into a cross section V shape. Therefore, the bearing has larger load capacity and is capable of standing about twice load by a simple calculation, as compared with a conventional ball bearing whose size is made the same. Because each of the outer/inner rings 1 and 3 comes into contact with the ball 5 at two points, run out of the outer ring 1 at the time of the revolution of the bearing can be prevented, strictness is not required for the control of a radial bearing clearance and the manufacturings of the outer/inner rings 1 and 3 can be facilitated by the degree.

Inventor: NORIHASHI HIROTAKA
IPC: G11B5/64
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a medium having the excellent stability of recording magnetization to external magnetic fields by overcoming the unstability of the recording magnetization of a perpendicular layer magnetic recording medium to the external magnetic fields. SOLUTION: The perpendicular magnetic recording medium 20 is made duller than heretofore in the reactivity of the magnetization of a ground surface soft magnetic film to the external magnetic fields by making the magnetic permeability of the ground surface soft magnetic film smaller than heretofore without forming the ground surface soft magnetic film as a film having good soft magnetic characteristics, by which the concentration of the magnetic flux of the external magnetic fields to the main magnetic pole of the perpendicular magnetic head is suppressed.  Therefore, the perpendicular medium which with which the demagnetization or degaussing of the magnetization recorded on the perpendicular recording layer by the external magnetic fields generated from a motor for disk rotation and a motor or the like used for head positioning hardly occurs and which has the excellent stability of the recording magnetization to the external magnetic fields may be obtd.

Title: Magnetic disk driving device
Inventor: TSUKADA MITSUYOSHI
IPC: G11B21/08
Filed: 1992-08-31
Abstract: PURPOSE:To stabilize the positioning of a magnetic head by adding a correction value to a speed command value in accordance with the remaining number of tracks and correcting manipulated variable for driving an access motor. CONSTITUTION:When a muCPU 7 receives a seak instruction, it reads the manipulated variable of the access motor for positioning a head 1a on a magnetic disk 2 as servo information by head 1a from the disk 2. The muCPU 7 judges whether the remaining number (n) of tracks attains the number N of starting decelerating action. In the case of n>N, a reference speed is read out from the memory of the CPU, and a speed error is obtained to perform servo arithmetic operation by a compensator arithmetic part 7a. When n<=N is attained, the reference speed is read out and the manipulated variable of the motor is controlled by the speed command value in accordance with the remaining number of tracks. In the case the speed of the motor becomes zero before the head 1a reaches a target track, the speed correction value is added to the speed command value so that the manipulated variable of the motor may be corrected.

Abstract: PROBLEM TO BE SOLVED: To provide an inspection method that can select a faulty battery before initial charging, does not generate heat abnormally, and can perform inspection quickly. SOLUTION: A closed circuit terminal voltage E at the time when a pulsive current is applied between the terminals of a secondary battery is measured, thus judging whether the battery is appropriate or not according to the closed circuit terminal voltage E. In this case, an internal resistance is equal to Rc and the closed circuit terminal voltage E when a pulsive current (i) is applied between the terminals of the secondary battery whose electromotive force is equal to E0 is equal to E0 + Rci. Although the internal resistance Rc changes due to the mixture of a foreign object, the shortage in electrolyte, and the like, which appears as the change in the closed circuit terminal voltage E according to the above expression. Failure such as the mixture of a foreign object and the shortage in electrolyte can be determined according to the change in the value.

Title: Process for acylation or alkylation of aromatic compound in hydrogen fluoride
Inventor: DANIERU DEII RINDOREI
IPC: C07C51/60
Filed: 1991-10-04
Abstract: A continuous process is disclosed for the acylation or alkylation of aromatic compounds in hydrogen fluoride. The aromatic compound is sufficiently insoluble in hydrogen fluoride that a two phase reaction medium forms. However, surprisingly, the product acylated or alkylated aromatic compound is soluble in hydrogen fluoride. The present invention particularly relates to use of a continuous, multi-stage process for carrying out the acylation or alkylation reaction. In the multi-stage process, the continuous phase can be either the hydrogen-fluoride rich phase or the aromatic compound-rich phase. The movement of the continuous phase relative to the non-continuous (dispersed) phase can be countercurrent or concurrent. The multi-stage process can be operated in a manner such that the aromatic compound feed to the reaction is entirely consumed or such that unreacted aromatic compound is recycled. <IMAGE>
