Title: Data retrieval system, portable terminal equipment and storage medium
Inventor: IMADA MASAYUKI
IPC: G06F21/60
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a data retrieval system or the like improved in safety by enciphering data to be exchanged and all data to be stored on the side of a portable terminal. SOLUTION: When copying and storing a DB 81 on a CF card 300, a PC 100 enciphers the DB 81 with a DB key, enciphers the DB key with a cipher password corresponding to a user and stores the DB on a DB card 300 together with the cipher password, and when performing access from the CF card 300 to the DB 81, a portable terminal 200 enciphers an inputted password with this password and discriminates whether that enciphered password is matched with the cipher password stored on the CF card 300 or not. When these passwords are matched, the DB key is deciphered by the cipher password and the DB 81 is deciphered by the DB key so that the DB 81 stored on the CF card 300 can be read.

IPC: H03F3/20
Filed: 1987-11-13
Abstract: PURPOSE:To prevent the breakdown of a power element by providing a control means for cutting off power source supply to a power amplifying circuit by a fact that a state that a detection voltage by a monitor means is in a prescribed value has continued for a prescribed time. CONSTITUTION:A monitor means is constituted of resistances 18-26, comparators 12, 13 and an OR gate 14. Also, a control means is constituted of a reference signal generating circuit 15, a counter 16 and a power source cutting-off circuit 17. When an 'H' level voltage is applied to an enable(EBL) terminal, the counter 16 counts a clock of a prescribed period supplied from the reference signal generating circuit 15. When an 'H' level voltage is outputted continuously from an OR gate 14, and during that time, the counter 16 has counted up to a count value which is set in advance, the counter 16 counts up, and also, generates an 'H' level signal. The power source cutting-off circuit 17 which received this signal cuts off electrifying to power elements 4-7 for forming a power amplifying circuit.

Title: Vane back pressure applying device for sliding vane type compressor
Inventor: HASEGAKI TAKAHIRO
IPC: F01C21/08
Filed: 1986-12-03
Abstract: PURPOSE:To prevent the malfunction phenomenon of a vane by providing a gas feed passage communicated to a vane back pressure chamber at one end and feeding gas for the volume fluctuation of the vane back pressure chamber. CONSTITUTION:A vane back pressure applying device 16 for a vane is provided on a rear side plate 7. When some time elapses after a stop of a compressor and the pressure difference between the high-pressure side and the low-pressure side becomes small, a spring 35 moves a plunger to a ball seat 29 side. Thereby, a gassy fluid is fed from the second gas feed passage 28 to a vane back pressure chamber 17 via the first gas feed passage 27 and an oil feed passage 18. Accordingly, the pressure reduction in the vane back pressure chamber 17 can be prevented, and the malfunction phenomenon of the vane can be prevented without impairing the durability of the compressor.

The value 4κt/W<2> is set, where W is the distance from the split line to upper and lower edges of the strip, κ is the coefficient of thermal expansion of the material of the strip, and (t) is the heating time of the pulse laser. The value D/W=0.1 when the set value is 0.0001-0.05; the value D/W=0.2 when the set value is 0.05-1.0, and the value D/W=0.4 when the set value is >=1.0, where D is the distance of the center position of the laser beam point heat source from the tip of the edge crack. The position of laser beam irradiation is set to the position of the corresponding D/W. The setup time is short, the heating point is best, and the splitting work does not take time, and can be automatic.

Title: Developer detecting device
Inventor: SHIMAOKA TAKASHI
IPC: G03G15/08
Filed: 1990-10-25
Abstract: PURPOSE:To prevent the lowering of detection accuracy by forming a developer detecting device of a developer detecting means provided with a detection face exposed to the inner face of a container for containing a magnetic developer, an agitating blade rotatably provided at the container, and a magnetic force generating member provided at the tip of this agitating blade in such a way as to be opposed to the detection face through a specified gap. CONSTITUTION:A magnetic developer in a container 15 is agitated by an agitating blade 20. The magnetic developer is sometimes attached to a detection face 19 even in the state of the residual level of the magnetic developer in the container 15 being lower than the detection face 19. In this case, the magnetic developer attached to the detection face 19 is separated from the detection face 19 because of being attracted by the magnetic force of a magnetic force generating member 21. An accurate detection signal is thereby outputted from a developer detecting means 18 according to the residual quantity of the magnetic developer in the container 15. Also, since the detection face 19 and the magnetic force generating member 21. are kept in the non-contact state, the degradation of the detection face 19 is prevented to enable the accurate detection of magnetic developer residual quantity over a long period of time.
