Abstract: PURPOSE:To prevent a third party from decoding a password number by providing a selecting means, which selects a single type of a figure out of the figures of a display means, a confirming means, and a panel, where the display means is provided at a position more hollow than a front surface. CONSTITUTION:A password number input means consists of a display means 21 to display the figures, a selecting means 22 to select a single type of the figure out of the figures on the display means 21, a confirming means 23 to confirm the selected figures, and a panel 24 where the display means 21 is provided at the position more hollow than the front surface. Consequently when a card possessing person inputs the password number, since the display means 21 is provided at the position more hollow than the front surface, it cannot be seen by the third party, and the motion of the finger of the card possessing person is only the operation of the selecting key 22 and the confirming key 23. Thus the third party cannot decode the password number by the input operation of the password number.

Title: Optical pickup
Inventor: NISHII KANJI
IPC: G02B7/28
Filed: 1983-04-20
Abstract: PURPOSE:To decrease the number of control manhours and to improve a record/ reproduction characteristic and the interchangeability by component parts, by attaching an elastic support member to a housing so that it can move within a plane orthogonal to the optical axis of an ojective lens and controlling the verticality between the optical axis of the objective lens and the bottom surface of an optical pickup. CONSTITUTION:The light delivered from an He-Ne laser 24 is reflected verti- cally by a reflecting mirror 21 and fed back to the output window of the laser 24 along the same optical path as long as the center axis BB of a lens barrel 11 is vertical to a base 22, i.e., the lower surface of a housing 18. If the axis BB is not vertical to the surface 20, the attachment position of an elastic support member holder 17 is moved to raise up the upper end of the barrel 11 in order to feed back the reflected light given from the mirror 21 to the output window of the laser 24. Thus the axis BB can be set vertical to the attachment surface of an optical pickup. As a result, the optical axis AA of an objective lens 10 which is stored coaxially to the barrel 11 is also set vertical to the attachment surface of the optical pickup.

Abstract: PURPOSE:To make it possible to perform accurate detection by taking out the defect signals of the surface of a material to be checked including roll marks by using a ring adder, comparing the signals with a reference level, and judging the presence or absence of the roll mark. CONSTITUTION:The detected defect signals are obtained by optically scanning the surface of the material to be inspected in the width direction.

CONSTITUTION:The concns. of the respective ions in the sample are determined by computation from both values of the absorbancy measured in the neutral region of pH5-10 of the sample soln. and the absorbancy measured in the acidic region of pH2-4 of the sample soln. at certain specific unit wavelength in the method of measuring the concn. of the NO3<-> and the concn. of the NO2<-> contained in the sample by measuring the absorbancy of the UV part in the sample by a UV absorption meter. The nitrous acid is a weak acid and the existence ratio of the ions as the NO2<-> decreases and the absorbancy decreases correspondingly if the pH of the sample soln. is adjusted to the acidic region. The respective concns. of the NO3<-> and NO2<-> are, therefore, independently measured by changing the pH of the sample soln. contg. the NO3<-> and NO2<-> and computing the concns. by the relation from both value of the absorbancy in the neutral direction and the absorbancy in the acidic region with the UV absorption meter of the single wavelength.
