Title: Information processor
Inventor: WATANABE ISAO
IPC: G06F1/30
Filed: 1991-05-08
Abstract: PURPOSE:To completely resume the input processing up to its final stage despite the occurrence of an unexpected power accident by providing a means to keep the voltage at the level for a prescribed time even in the abnormal state of the power voltage. CONSTITUTION:A voltage holding means 2a holds the voltage at the level for a prescribed time even in the abnormal state of the voltage of a power supply 10. An interruption means 4 applies the interruption to an information processing means 5 based on the voltage of the means 2a when a voltage detection means 3 detects the abnormality of voltage of the power supply 10. In such constitution, the data initialized at a relevant time point or the volatile data is stored in a nonvolatile storage means 8 via the means 2a even if the supply of power is suddenly stopped to the means 5. Then the data saved in the means 8 is read out when the power voltage is reset to a normal state. Thus the power supply can be resumed up to a state set right before an abnormal state. Therefore the data can be inputted continuously when the power supply is turned on without wasting the data that are continuously inputted up to a time point set right before the abnormal state of the power supply.

Title: Negative actuation type electromagnetic brake
Inventor: NISHIOKA TAKESHI
IPC: F16D55/36
Filed: 1987-04-25
Abstract: PURPOSE:To decrease the change of a brake torque as well as a retaining torque by making the minimum gyration radius of a portion contacting a brake disk, an armature and a side plate more than 0.9 times the maximum gyration radius. CONSTITUTION:A brake disk 21 is spline-combined at a rotary shaft P, and an its perimeter portion is formed in a body a tubular contact portion 22 whose both end surfaces are made to protrude on an armature 3 side and an side plate 8 side. This contact portion 22 is so set that an inside diameter is more than 0.9 times against an outside diameter. Accordingly, the armature 3 is sucked to a field core 5 at the time of electrification to a coil 6, and also, is pushed against the brake disk 21 by a spring 7 at the time of non- electrification to the coil 6. Because of this, if the frictional coefficient of the contact portion 22 is constant, the change of a retaining torque can be suppressed to within about 10% of the maximum value.

Title: Die with elliptic internal die hole
Inventor: MIZUTANI IWAO
IPC: B23P15/24
Filed: 1981-07-01
Abstract: PURPOSE:To obtain a die nib which has less internal stress concentration and an elliptic internal hole close to a circle, by applying pressure to the die nib by an external ring through two intermediate rings in specific shapes which have difference coefficients of elasticity. CONSTITUTION:An intermediate ring 12 is pressed in an external ring 14 which is sufficiently thick and the ring 12 is contracted in radius directions by an extent nearly equivalent to a pressing-in margin. Similarly, a die nib 10 is pressed in this ring 12 and a clamping force which corresponds to its pressing-in margin is applied to the die nib 10, which is contracted in radius directions. Namely, the pressing-in force by the ring 14 is applied to the die nib 10 through the ring 12. In this case, the coefficient of elasticity of the 1st split piece 16 of the ring 12 shown in the figure is greater than that of the 2nd split piece 18. Therefore, the internal hole of the die nib 10 deforms by being contracted inwardly where the piece is present than where the piece 18 is present. Namely, the internal die hole of the die nib 10 is formed in an ellipse close to a circle while having a short axis in the direction where the piece 16 is present and a long axis in the direction orthogonal to said short axis.

Title: Protective case of electric-heater temperature control section

IPC: H05K7/14
Filed: 1988-04-26
Abstract: PURPOSE:To interrupt the specific region of the rear of a printed board surrounded by the plane section of a first case and the surface of the printed board surrounded by the wall surface of a second case from the outside air by pushing and fast sticking the printed board onto the plane section of the second case by the wall surface of the first case. CONSTITUTION:When a case 2 and a case 3 are combined while a printed board 4 is arranged into the inside, the outermost whole circumference of the specific region of the rear of the printed board 4 is fast stuck to the plane section of the case 2 set up so as to correspond to the outermost whole circumference because the printed board 4 is pushed toward the case 2 by the wall surface of the case 2. The pushing force to the printed board 4 of the wall surface of the case 2 represents reaction to compressive stress generated at a time when the case 2 and the case 3 are combined, and the wall surface of the case 3 pushes the surface of the printed board 4, thus also attaching the surface of the printed board 4 and the wall surface of the case 3 closely.

Filed: 1995-04-27
Abstract: PURPOSE:To provide an inexpensive piezoelectric sounder with stable frequency characteristics by placing a circumferential ridge of a diaphragm onto a step difference face of a sidewall inside a resin case whose sprint terminal is subjected to insert-molding, a part of the sidewall is melted while an outermost circumferential ridge of the diaphragm is floated due to a recessed part and applying thermal caulking to the circumferential ridge of the diaphragm. CONSTITUTION:A resin case 12 having a flat part 12a and a sidewall 12b with a margin of a melt part 28 is subjected to insert molding together with a terminal board 18. A step difference face 32 having a recessed part 30 in its inside is formed to the inside of the side wall 12b. A circumferential ridge of a diaphragm 22 is placed on the step difference face 32 so that the piezoelectric body 24 fixed to the diaphragm 22 is in press contact with a spring terminal 18b and in close contact onto the step difference face 32 in this state. However, the outermost circumferential ridge of the diaphragm 22 is floated by the recessed part 30. While the circumferential ridge is in close contact, the melt part 28 is heated and the material of the softened melt part 28 is used to fix the diaphragm 22. Since the recessed part 30 is provided, no caulking stress is exerted and deformation such as bent is not caused to the diaphragm 22.
