Title: Image pickup device and electronic still camera
Inventor: NAKAYAMA MASAAKI
IPC: H04N5/376
Filed: 1988-03-18
Abstract: PURPOSE:To raise the saturate signal level of a solid-state image pickup element so as expand the dynamic range of the element by switching not only the waveform of the drive pulse impressed upon the element, but also the crest value or the crest value and DC potential in a state where the switching is interlocked to the switching of the scanning method of the element. CONSTITUTION:Across a drive circuit 4 a voltage group which does not change irrespective of scanning states is directly applied from a drive voltage generating circuit 6 and another voltage group which is changed in accordance with the scanning states is selectively applied through a changeover switch 5. Moreover, upon the circuit 4 a pulse group which is common irrespective of scanning methods is directly impressed from a drive pulse generating circuit 9 and another pulse group which is changed in accordance with the scanning methods is selectively impressed through a changeover switch 8. The switches 5 and 8 are switched by means of the command of a scanning state changeover switch 7 and when the 1st scanning method A is commanded, both switches 5 and 8 are set to terminal A sides. When the 2nd scanning method B is commanded, both switches 5 and 8 are set to terminal B sides. Therefore, the saturate signal level is raised to almost an ideal value in each scanning method, since the saturate signal level is set to almost the optimum value in each scanning method.

Title: A device for automatically stopping the rotation of a hose reel in tank truck
Inventor: TAKEMURA KOUJI
IPC: B65H63/08
Filed: 1981-05-06
Abstract: PURPOSE:To prevent damage to a hose at its starting end connected to a tank by providing a device for automatically stopping the revolution of a hose reel when the hose has been completely let out. CONSTITUTION:A hose 10 passes through guide rollers 20 and a hose passage window 11 to be wound on a core cylinder 3 of a reel 2. When the hose 10 is wound in like this, the winding force of the hose presses a ? shaped arm 16 against the outside surface of the core cylinder 3 and a rotating shaft 14 and a link 17 turn counterclockwise to be held between the hose 10 and the core cylinder 3 by the tension of a spring 18 which has been stretched by their motions. When the hose is reeled out nearly completely, the ? shaped arm 16 spreads out to rub against the inside surface of a cover 9 thereby to brake the revolving motion of the reel 2, thus making it possible to prevent the reel from turning excessively and to avoid damage to the hose at its starting end so that the working efficiency may be so much improved.

IPC: B42D15/10
Filed: 1988-03-18
Abstract: PURPOSE: To prevent an electronic card from illegally being used by comparing a ciphered codes by a discriminating circuit provided on the electronic card. CONSTITUTION: The secret code (e.g. 50 bytes) on the IC card 50 is stored in the 1st address of a memory 1. Then, this secret code is read out and compared by a comparator 2 with a code supplied from a transmission device 60. When they match with each other, addressing and writing are enabled. When not, on the other hand, an address counter 17 is reset at the end of the comparison cycle. Consequently, since it becomes impossible to know the position of the 1st bit of the discrepant code, the secret code needs to be deciphered from the beginning of the 50 bits and a longer time is needed.
