Title: Validity confirming device for medium for card check system
Inventor: HORIE KIYOSHI
IPC: G06K17/00
Filed: 1989-04-20
Abstract: PURPOSE:To prevent a wrong check result due to ineffective check data from being outputted by deciding whether or not the validity of a recording medium where check data is recorded is effective automatically and inhibiting the recording medium from being read unless the validity is effective. CONSTITUTION:This device is equipped with a validity starting date memory 1, a validity ending date memory 2, a timer 4, a memory 5, and comparison parts 7 and 8 and also equipped with an OR circuit 10 and a read inhibiting circuit 20. When the output of the OR circuit 10 is 'high', the outputs means that the validity of an optical card 35 expires and the read inhibiting circuit 20 inhibits an optical card reader 40 from performing read operation according to the output of the OR circuit 10. Consequently, the wrong check result due to ineffective check data is prevented from being outputted.

IPC: G01N15/06
Filed: 1988-04-27
Abstract: PURPOSE:To enable the determining of the concn. of an aqueous solution easily and accurately, by measuring a remarkable swelling volume which occurs in a water sucking process of a water absorbing polymer. CONSTITUTION:A tubular container 1 has numerous pores 2 on the tube wall thereof and has a scale 3 on the surface thereof to house a fixed amount of a water absorbing polymer 4 inside. The water absorbing capacity of the water absorbing polymer 4 is maximum with pure water and reduces according to the concn. of the solute though affected by the nature of a substrate. Therefore, a fixed amount of the water absorbing polymer 4 is brought into contact with a sufficient amount of salt water, for instance, to prepare a calibration curve indicating a relationship between a volume of the polymer and the concn. of the salt water. This enables the determining of the concn. of the salt water with an unknown concn. handily by measuring a swelling volume which takes place in a water absorbing process of the polymer 4.

Abstract: PURPOSE:To prevent the occurrence of a disturbance of a reproducing sound in a mode changing part by changing a standard mode to a long time mode at the time when the level of a sound signal becomes lower than a prescribed value. CONSTITUTION:During video recording with a timer, a video recording residual time 100 from a timer circuit 1 and a tape residual amt. time 200 from a tape residual amt. measuring part 3 are inputted, and when it is decided that the tape is short, the time for changing the standard mode to the long time mode is calculated by a video recording mode changeover program 21. On the other hand, the sound signal level 400 is inputted from a sound level detecting circuit 5 to the program 21. Then, when the time for changing the video recording mode has come, and when the sound level 400 is more than the prescribed value, no changeover is made by a system microcomputer 2, and when it becomes below the prescribed value, the speed is dropped to the long time mode. Consequently, at the changing time, only the sound less than the prescribed value is inputted, so that the disturbance of the sound can be prevented.

Abstract: PURPOSE:To stop the repeat of loading/ejecting operation at the time of turning off of a main power supply switch and to prevent a battery from voltage drop by constituting the titled device so that a controller does not receive a disk carrying command during the control of disk carrying at the off of the switch. CONSTITUTION:A CPU20 detects the off of the main power supply by an output from a detecting circuit 31, decides the existence of an eject command of an operation group 5, and when the command exists, generates an eject command to a loading motor to a motor driving circuit 30. The CPU20 decides the existence of a load command from the group 5 after the generation of the eject command, and at the absence of the load command, detects the completion of the ejecting operation and and is turned to an operation stop state. At the absence of the command, key entry is neglected. Since a disk reloading command is not accepted during the ejecting of the disk by the off of the main power supply, the loading operation and the eject operation are not repeated and the battery can be prevented from voltage drop.

Abstract: PURPOSE:To enable evaluation of time response characteristic as well as non- linearity of non-linear material, by projecting light to a sample from a pulse light source with the wavelength larger than that at the absorption end of the sample through a filter which transmits only light required for the excitation of the sample. CONSTITUTION:After changed in the direction of traveling with a hot filter 2, light from a glass laser 1 oscillating with the wavelength larger than that at the absorption end of non-linear material is made to pass through an infrared ray transmitting filter 3 and focused with a lens 4 to irradiate a non-linear sample 5 arranged on a glass plate 6. Light generated from the sample 5 thus excited is collected with a lens 7 to a slit of a spectroscope 8.

Since a signal appears at the position corresponding to the wavelength of the specified high harmonic component on the surface of a monitor tube of the camera 9, the linearity of the sample 5 can be determined by measuring the intensity and continuation time thereof.
