Title: Fireproof construction
Inventor: IKEDA KENICHI
IPC: E04B1/94
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To improve the constructing property and reduce the cost by covering the circumference of a steel member such as beam or column with a fireproofing material consisting of timber, and using the covering material also as a finishing material to dispense with the spraying of rock wool or the mounting of the finishing material. SOLUTION: A fireproofing covering material 6 consisting of timber is mounted around a steel member 2 consisting of H-steel or the like, so that the heat is insulated by a carbonized layer formed on the surface, even if burnt in a fire, so that the internal temperature does not become high. The fireproofing covering material 6 is used also as a finishing material as it is in a building having a woody interior design. When the steel member 2 is a column, the whole circumference is covered, and this covering material 6 is applicable to square steel without being limited to H-steel. The spraying work of a fireproofing covering material or the mounting of a finishing material is dispensed with to facilitate the construction and improve the working environment. Accordingly, the cost can be reduced.

Title: Regulator for ink jet recorder
Inventor: OOHORI TAMIO
IPC: B41J2/08
Filed: 1981-11-20
Abstract: PURPOSE:To correct a change generated in a graining process of a nozzle as a result of a change in a nozzle shape due to electrolytic corrosion, by regulating an exciting voltage of a printing head in accordance with a time spent in a printing. CONSTITUTION:A graining region of a nozzle varies with the number of printing papers covering over a long period of time. A change is produced at an upper limit A and a lower limit B of an exciting voltage Vp of a piezo-electric vibrator of a printing head for a change control type ink jet recorder in which a dystuff system solution serves as ink and a metal nozzle is used. For example, if the exciting voltage Vp of the piezo-electric vibrator is set to a center of a workable region C, in an initial exciting vibration voltage Vp, the exciting vibration voltage, produced after 70,000 copies of standard originals of an A4 size are printed, attains 42V, and it increases by about 2V each time 10,000 sheets are printed. Thus, if the exciting vibration voltage Vp is regulated by 2V each time 10,000 sheets are printed, this causes insuring of reliability of a printing covering a long period of time.

Title: On-line diagnostic system for multiplex memory device
Inventor: ISHIBASHI EIJI
IPC: G06F11/22
Filed: 1990-07-17
Abstract: PURPOSE:To enable a CPU to perform an on-line diagnosis of a multiplex memory device by giving an access to a memory unit separated from a system through a memory control means as long as a diagnostic task is shown. CONSTITUTION:A multiplex memory diagnostic program 41 is started and a test mode flag 22 is turned on. Thus an access is given only to an on-line memory unit 12 at a machine word instruction level. If an error is generated by an access given to a multiplex memory device 10 with the flag 22 kept turned on, this information is given to a CPU 20 in the same way as an error that is generated in a normal access. The CPU 20 carries out an error interruption processing routine under the control of an OS 40 in order to check the state of the flag 22. Thus it is possible to decide whether an error is generated or not at an access of the device 10 carried out based on the program 41. Therefore an error interruption processing routine can be branched into an error processing routine included in the program 41. Thus the CPU 20 can perform a proper treatment.

CONSTITUTION:Inductance L of an exciting coil 3 is obtained by an expression I, where G is the gap length of an electromagnet having a shape as shown in the Figure, S is the area of the gap, mu is the permeability of an iron core and N is the number of turns of the winding of the exciting coil 3. Of these, since the values of mu, S and N are constants for the electromagnet, the gap length G is inversely proportional to the inductance L. Meanwhile, the inductance L of the exciting coil 3 can be expressed by an expression II by an exciting current I and an induced electromotive force E. Therefore, the gap length is proportional to (dI/dt)/E. Namely, when the change speed dI/dt of the exciting current is divided by the induced electromotive force E, the gap length G can be obtained.
