Title: Password input system for changing arrangement of numbers or symbols
Inventor: KISHIMOTO TAKUYA
IPC: G06F3/02
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To easily input a password without stealing a glance at the password from the third person in the case of inputting the password for a burglar system to be locked/unlocked by inputting the password. SOLUTION: Concerning this password input system, a password input device or an input display part is changed and an input position is changed at every designated number of times. Thus, since the pushing position of an input button or the like is changed, the third person can not specify which number is inputted from the input position. Therefore, the password number is not embezzled.

Title: Method and device for sequential determination of light wavelength
Inventor: SHIMIZU FUJIO
IPC: G01J9/02
Filed: 1980-08-28
Abstract: PURPOSE:To improve the precision of the measurement of the wavelength of continuous or pulse light by using two interferometers which increase in interference length gradually and by making a sequential approximation of the wavelength of light to be measured from a known standard position on the basis of the position of the characteristics point of the measured light and the order of interference. CONSTITUTION:Light L0 to be measured or reference light L3 is split by beam splitters M0-M4 and applied to, for example, optical interferometers I1-I4 of Fabry-Pe rot etalon. The interferometers I1-I4 increase in interference length gradually and photodiode arrays R1-R4 convert interference rings projected from respective optical interferometers into electric signals, which are outputted to A/D converters AD1-AD4. Digital signals from the AD1-AD4 are supplied to a computer MC for wavelength calculation. The standard positions of the interferometers I1-I4 are found by the reference light L3, and the characteristic points are also found by the bright or dark point of the interference light of the measured light L0, thus finding primary - quadratic approximate wavelengths.

Filed: 1987-05-15
Abstract: PURPOSE:To prevent an eyesore signal from outputting at the time of using a video signal dedicating regenerator without a sound reproducing function by discriminating and storing a recording signal of each block of a recording medium, and reproducing selectively a block among individual blocks based on this storage information. CONSTITUTION:When a disk 1 is set up, all tracks are reproduced and the recording signal of each block is discriminated whether the sound signal or the video signal by a reproducing discriminator circuit 17, and then the outcome of the discrimination is stored in a built-in memory of system controller 18.
