Title: Driving circuit for oscillatory motor
Inventor: SHIMIZU MASAO
IPC: H01L41/04
Filed: 1988-05-30
Abstract: PURPOSE:To prevent a motor from being suddenly stopped, by composing the motor to make its frequency slightly higher immediately before the resonance driving of the motor, and by setting a second comparator for detecting the driving of the motor with second frequency, additionally. CONSTITUTION:The driving circuit of an oscillatory wave motor is composed of phase comparators 2, 20, a high-frequency filter 3, a voltage controlling oscillator 4, a frequency divider 5, shift registers 6 to 7, amplifiers 11 to 12, level comparators 15 to 16, a counter 21, a magnitude comparator 22, a data latch 23, and a CPU 24. Then, a second data latch 26 latches a data set from the CPU 24, and a second magnitude comparator 25 compares the output of the counter 21 and the set value of said latch 26 with each other, and when the output of the counter 21 is less, then the output of signal H is generated. In this case, at the time of starting the motor, by the signal H, the lowering of the frequency is stopped through the CPU 24, and its state is kept, and driving is stabilized.

Title: Threshold voltage variable type amplifier circuit
Inventor: KOYAMA MIKIO
IPC: H03K3/353
Filed: 1982-07-30
Abstract: PURPOSE:To attain low voltage operation, by adopting 3-stage of transistors (TRs) in a threshold voltage variable amplifier circuit comprising complementary MOSFETs. CONSTITUTION:When a voltage at an input IN increases from 0V and reaches, e.g., to 2.5V, N-FETs 52, 54 are turned on. Since a circuit point 61 is set to a value close to VDD (5V), the circuit point 61 keeps almost 5V, a terminal OUT goes to 0V and the polarity of the OUT is not inverted. When an input voltage IN increases further and reaches 4V, the potential at circuit points 61, 62 go to the vicinity of 0V, the terminal OUT goes to the VDD(5V) by being drawn to the voltage change, and the polarity of the OUT is inverted. Then, when the input IN is at 5V, the circuit point 62 is 0V and the OUT goes to the VDD(5V). Although P-FETs 51, 53 are turned off, an N-FET56 is turned on. When the input IN is decreased to 1V, the circuit points 61, 62 go to the vicinity of 5V and the OUT goes to 0V by being effected with it and the polarity of the OUT is inverted.

Title: Rotary valve mechanism for internal combustion engine
Inventor: ASAKA URATAROU
IPC: F01L7/02
Filed: 1979-10-15
Abstract: PURPOSE: To raise the efficiency of charging fuel into a combustion chamber, by making the diameter of an inlet port formed in the body of a rotary valve smaller than that of an outlet port,  producing a greater centrifugal force at the outlet side by reason of the difference in the centrifugal force produced when the body of the rotary valve is rotated, and thereby increasing the velocity of fuel flow.  
     CONSTITUTION: An inlet port D is formed in the body 106 of a rotary valve at a portion of the  circumference around a small-diameter portion 106a. The inlet port D is connected to one end of  a intake passage A formed radially in a medium-diameter portion 106b in the manner that it is  curved from the small-diameter portion 106a toward the medium-diameter portion 106b. The  other end of the intake passage A is opened at a portion of the circumference around the medium- diameter portion 106b for forming an outlet port F. This outlet port F is formed on the same  circumference of portion 106b where an exhaust-gas inlet port M is formed, but it is located with  a proper phase difference to the port M, so that the port F comes into registry with an opening N  selectively. In housing 105, there is opened an outlet port I of a fuel supply passage connected  selectively to inlet port D. With such an arrangement, fuel drawing and charging efficiency can be  improved by the difference of centrifugal force that is causedly the difference of  diameter of inlet  port D and that of outlet port F.

Title: Storage device with secrecy protection mechanism and secrecy protection system using the same
Inventor: SHORIKI KEI
IPC: G06F21/60
Filed: 1994-06-15
Abstract: PURPOSE:To protect the secrecy of stored data without manually inputting identification information by a user. CONSTITUTION:A magnetic disk device 2 where the data are stored is freely attached to and detached from a host 12. When the power source is turned ON, a discrimination information transmission command is sent out of the disk drive 2 to the host 1. In response to the command, the stored data are allowed to be accessed only when identification information inputted from the host 1 is matched with the identification information of the disk drive. Further, the access to the data is allowed only when the identification information is inputted within a specific time clocked by a timer 27 after the identification information transmission command is sent out. If the disk device 2 is stolen, its data can not be accessed since identification information does not match or is not inputted within the specific time, so that its secrecy is protected.

Title: Damping device
Inventor: ISHIKURA SHUICHI
IPC: F16F7/10
Filed: 1989-05-29
Abstract: PURPOSE:To slide more smoothly the construction of a ball thread part and reduce the production of trouble such as scuffing, etc., by forming a string thread part with string made from string-shaped lubricant on the thread part of a mechanical snubber. CONSTITUTION:When a vibration 11 is generated on the vibration-isolated side, a load is transmitted to a string thread 6 through a rod 5. The string thread 6 is constructed of string 3 made from lubricant such as string-shaped polyacetal resin, etc. In this state, the axial linear movement of the rod 5 is converted to the rotary movement of a shaft 7 through the string thread 6. The rotary movement of the shaft 7 is then guided by bearings 8 in the main body 4, the shaft can be rotated stably, and rotary movement of an inner wheel 9 is induced. Since the inner wheel 9 is provided with a large inertia moment relative to rotation, the rotary angular acceleration of the inner wheel 9 is large for the relatively high speed movement such as earthquake and the other vibrations and, therefore, vibration-proofing effect is given due to rotary inertia force effect.

CONSTITUTION:According to a travel starting command from a ground transmitter 50, a car-borne equipment suspended on an overhead wire starts self-traveling. Then, the introductions of the signal from a part 10 for sensing the flaw of the overhead wire and the signal from a rotary pulse sensor 37 for sensing the position of the flaw on the aerial wire are performed. When there is any flaw on the overhead wire, an amplitude signal data and the data of a rotary pulse counter are stored in a memory in succession. Further, a control part 20 for storing these data in a removable memory medium is provided. Since in such a manner the car-borne equipment can be made to travel and stop on the overhead wire by the ground transmitter 50, flaws on the overhead wire can be sensed accurately. Also, since the sensed data are stored in the removable type memory medium, the detection data can be analyzed easily on the ground.
