Abstract: PURPOSE:To secure stable driving as well as a feeling driving in time of ordinary driving regardless of curving conditions, by making a suspension characteristic into hard with turning start detection, while constituting it so as not to be restored to a normal stage till the turning is over. CONSTITUTION:Information on a steering angle 2, a car speed 3, acceleration 17 and the like are all inputted into a control unit 1.

Title: Method for demagnetization of thick steel plate
Inventor: TSUGAI HIROMICHI
IPC: H01F13/00
Filed: 1983-04-04
Abstract: PURPOSE:To enable the AC demagnetization of thick steel plates of 30mm. thick or more by a method wherein demagnetizing frequency of an AC flowing in a demagnetizing coil is converted by a frequency converter according to the thickness of the steel plate so as to maintain demagnetizing power by supplementing a decline of it caused by the skin effect. CONSTITUTION:When residual magnetism of a steel plate 1 is demagnetized, induced voltage and operating time of an induced voltage adjuster 3 are controlled and alternating current generated by a transformer 4 is flowed into a demagnetizing coil 2, thereby driving the residual magnetism of the steel plate 1 into a direction of zero so as to attain magnetization. Nextly, in case of a thick steel plate of 30mm. thick or more, a frequency of the AC (a demagnetizing current) generated by the transformer 4 is decreased by a frequency converter 5 so that it might have the wave form close to that of a direct current. Consequently, as the magnetizing time becomes longer, the residual magnetism even of the central portion of the thick steel plate can be AC-demagnetized.

Abstract: PURPOSE:To prevent the movement of a packing and the loosening or the sag of filter cloth and a net-like substance, by a method wherein a filter frame having the net-like substance arranged to the innner peripheral surface thereof is covered and clamped with filter cloth and a seal material is attached to the filter cloth adjacent to a filter plate along both side surfaces thereof. CONSTITUTION:A net-like substance 5 is arranged to the inner peripheral surface of the frame body 12 of the filter frame 2 in a multiple filter press and the whole is clamped by filter cloth 4. A seal material, for example, an O-ring is arranged to the side surface of the clamping filter cloth 4 and enclosed in a cylindrical part formed by sewing both sides of a tape 11 and the filter cloth 4. In addition, because a spacer 15 limiting the collapse of the O-ring is attached to the frame body 12 while a water draining net like substance 16 is attached to the surface of the plate body 13 of the filter plate 3, processing cost is made low and a seal material 10 is not moved while the net-like strip plate clamping filter cloth 4 is not loosened and the sag of a net-like strip plate 5 is prevented.

Title: Ultrafine powder laver and its application
Inventor: IRIE KEIKO
IPC: A23L17/60
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To solve a problem in which nutrients in laver are not sufficiently utilized because of undesirable digesting and absorbing properties of the laver, though the laver abundantly contains nutrients such as proteins, minerals and vitamins. SOLUTION: This ultrafine powder laver is obtained by pulverizing laver into a size of 1 μm to 100 μm. Furthermore, the laver may be baked before ultrafine pulverizing treatment. The cells (cell membranes) of the laver are completely broken and internal cytoplasms and nucleoplasms are exposed to the outside by the ultrafine pulverizing treatment. As a result, the nutrients can rapidly and readily be absorbed.
