Title: Floor nozzle for cleaner
Inventor: HIROSE TORU
IPC: A47L9/04
Filed: 1987-08-28
Abstract: PURPOSE: To provide a floor nozzle for a cleaner with improved sound absorbing effects for inhibiting a sound absorbing material from obstructing an air flow by providing a freely extendible and contractible sound absorbing material between a partition plate provided with a sound absorbing part and the side wall of a turbine chamber. CONSTITUTION: The partition plate 12 is installed almost parallelly to the side wall 13 of the turbine chamber 6 and is brought to a position facing the tip of a turbine 1 when a main intake hole 9 is closed. The freely extendible and contractible sound absorbing material 14 with full of flexibility is installed between the partition plate 12 and the side wall 13 of the turbine chamber. The partition plate 12 is provided with the sound absorbing part 16 composed of many holes. In a state where the main intake hole 9 is closed, noise generated when a jet collides with the turbine 1 is absorbed to the sound absorbing part 16 of the partition plate 12 present at the position facing the turbine 1 and the noise is attenuated by the sound absorbing material 14.  In the state where the main intake hole 9 is opened, the sound absorbing material 14 is compressed and it does not become the obstruction of an air passage. At that time, since the turbine 1 is not rotated, the noise is lessened and a problem does not occur.

Filed: 1990-08-16
Abstract: PURPOSE:To obtain a piezoelectric actuator in which micro positioning in the direction of theta can be carried out through a simple system by providing a multilayer torsional displacement piezoelectric element with a driving means for producing a static torsional distortion in the direction of lamination. CONSTITUTION:An applying voltage V corresponding to a target rotational angle Po is determined based on the target rotational angle Po and a holding time To according to a formula representing the relation between a previously inputted rotational angle and the applying voltage. A torsional element 3 is then driven with thus determined applying voltage and at the same time measurement of time T is started. A judgment is made whether positioning of an output shaft 9 has just started. Upon elapse of predetermined seconds after start of time measurement, a judgment is made whether the number P of output pulses from a rotary encoder 10 matches with the target rotational angle Po. If they match with each other, a judgment is made whether the time T elapsed after start of measurement is longer than the holding time To and the control is completed if T is longer than To.

Filed: 1988-09-01
Abstract: PURPOSE:To prevent the buckling of a suspension and to suppress the reduction of a reproduction efficiency accompanying a rolling by fitting a magnet and a holder at a yoke and positioning a fixed coil into a magnetic gap. CONSTITUTION:Between a U-shaped part 13a to execute the action as a yoke 13 and a magnet 14, a magnetic gap is formed. A focus coil 18 and a tracking coil 19 are positioned in a magnetic gap. For this reason, even when the U-shaped part 13a and the magnet 14 due to these are operated, an effective magnetic flux part is slipped off from coils 18 and 19 and the sensitivity reduction does not occur. Since the yoke 13 and the magnet 14 are formed in a single body, the suction force to occur between them does not give the bad influence to a holder 12 and a suspension 15 of an objective lens 11. Consequently, the buckling of the suspension 15 and the rolling phenomenon of the holder 12 do not occur.

Filed: 1990-08-17
Abstract: PURPOSE:To confirm whether a generator and contents are changed or not by encoding a program including an identifier indicating the generator to generate an authenticator and checking the authenticator and decoding the program to check the authenticator at the time of using the program. CONSTITUTION:The program inputted from a bus 1-4 together with the authenticator is temporarily stored in a memory or the like.

Title: Method for adjusting bottom dead point of press
Inventor: KOZU KIYOSHI
IPC: B30B15/06
Filed: 1992-08-18
Abstract: PURPOSE:To adjust the bottom dead point of press in a real time during working a machine by adjusting a bottom dead point variation of a press with the addition and subtraction of the number of strokes of the slide. CONSTITUTION:In a machine press 10, a slide 1 is moved up and down on the upper side of an opposed bolster 2. The position of the bottom dead point P of this slide 1 is changed by the inertial force due to the number of strokes every minute. Fur example, it is changed almost linearly from about 15mum at the time of 200 revolutions per minute to 80mum at the time of 1,200 revolutions per minute. When the movement of the machine press 10 is stavted in consideration of this correlation and the bottom dead point is lowered due to the thermal expansion with the temperature rise, the correction for elevating the bottom dead point can be executed by making the number of strokes small.

Abstract: PURPOSE:To surely prevent the entering of static electricity or noise signals, etc. into a memory card from the external even when they are impressed by executing the cutting-off by means of duplex switch elements. CONSTITUTION:At the standby of a memory, by turning the voltage of a control signal impressed to a control signal terminal B to a low level, the control voltage supplied to the switch elements A12, An2 can be quickly lowered to the low level by means of a resistor R4, thus the switch elements A12, An2 are turned OFF, to cut off input signals I1, In. Moreover, when the memory card is extracted or the external power source is cut off, the control voltage supplied to the switch elements A11, An1 is quickly lowered to a low level by a resistor R3 to turn OFF the elements A11, An1. In such a time, the switch elements A12, An2 are also turned OFF. Thus, the connection between the card I/O terminals I1, In and the I/O terminals I1', In' of the memory are cut off in double manners.
