Abstract: PURPOSE:To make it possible to obtain excellent magnetism and high insulation resistance, by after mixing, sintering provisionally and crushing a mixture of BaO or SrO and Fe2O3 materials and adding to the mixture a Ba or Sr compound and then forming and sintering them. CONSTITUTION:In manufacturing oxide permanent magnets of magnetoplumbite type with a chemical formula: MO.Fe2O3 (M is Ba or Sr, and n is mol ratio by 5-6) their main ingredients and auxiliary ingredient added as needed are weighted, mixed, sintered provisionally and crushed. Then, after a Ba or Sr compound is added to the mixture, it is formed and sintered. Between Fe2O3 or Fe<2+> that  is thereby left and a newly added compound of Ba or Sr solid phase reaction is developed to obtain a magnetoplumbite phase, in which the Fe2O3 ingredient is made as little as possible for much improving the insulation resistance of the sintered mixture. It is preferable to add the Ba or Sr compount in the amount of 0.05-3.0wt% of the ferrite.

Title: Clock interruption detection circuit
Inventor: KOMATSU KAZUTOSHI
IPC: H04L7/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a clock interruption detection circuit detecting accurately interruption of a superimposed clock. SOLUTION: An edge detection section 10 generates an edge detection signal S10 of a superimposed clock PCK. A master clock MCK is frequency-divided by a frequency division counter section 20 into a clock S20. The clock S20 is given to a phase shift section 30, in which a clock S30 is generated. The clock PCK is sampled by a clock missing detection section 40, in which an (on-off-on) pattern detection signal S40a and an off pattern detection signal S40b are generated. Furthermore, the clock S20 is frequency-divided by a frequency division counter section 60, in which a count S60ct of a 400Hz clock is generated.  After the (on-off-on) pattern detection signal S40a is detected based on a timing of the clock S20 by an interrupt detection protection section 50, number of times of the generation of the (on-off-on) pattern detection signal S40a and the off pattern detection signal S40b is respectively counted in a timing of the count S60ct and when the count reaches a preset protection stage number, a clock interrupt detection signal S50D is generated.

IPC: H02K15/16
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To reduce windage loss for improvement of efficiency by applying low-viscosity varnish and then high-viscosity varnish at the time of applying varnish to an armature. SOLUTION: To ensure mechanical strength sufficiently high enough to withstand centrifugal force during rotation between coils or the coil and electric insulation by integrating a coil and an iron core 20 with varnish, a sufficient amount of varnish is applied in a slot using low-viscosity varnish. Varnish is then applied to a coil surface at the end part of the iron core 20 again using high-viscosity varnish, so as to eliminate the roughness of the coil surface at the end part of the iron core 20. It is thus possible to reduce the windage of a motor easily and obtain a highly efficient motor.

Abstract: PURPOSE:To carry on a transaction by switching to a stand-by machine if an in-use machine enters a system-down state by disconnecting the power source when the system diagnoses itself to judge the normalcy of the stand-by machine. CONSTITUTION:In the system provided additionally with the stand-by machine 2 which carries on the transaction as a substitute for the in-use machine if the in-use machine becomes abnormal, self-diagnoses of the in-use machine and stand-by machine 2 are taken in parallel at the time of, for example, initial powering-ON operation, but when the stand-by machine 2 is in a stand-by state, the power source of the stand-by machine 2 is temporarily turned on by a powering-ON means 3a when necessary. When the transaction ends normally, a powering-OFF means 3b turns off the power source of the stand-by machine 2, which enters the stand-by state, but when the transaction ends abnormally, a warning means 5 generates a warning. Consequently, the stand-by machine 2 in the stand-by state can easily diagnose itself at any time from any place not to mention the initial powering-ON operation, and can be put in the stand-by state by being powered off in the normal state to reduce the power consumption, thereby preventing the device, components, etc., from deteriorating.
