Title: Optical probe
Inventor: MITSUZUKA SHIYUUICHI
IPC: G01H9/00
Filed: 1984-06-05
Abstract: PURPOSE:To measure easily a standing wave ratio of an elastic surface wave by irradiating a laser beam to an elastic surface wave element, making its + primary diffracted light and the - primary diffracted light interfere with each other, and varying a path difference of both the diffracted lights. CONSTITUTION:An optical probe is constituted by adding reflecting mirrors 131, 132 and 133, a semitransparent mirror 15, a movable mirror 17, etc. In this state, the elastic surface wave is excited in an element 6 by a high frequency oscillator 5, and a laser beam (a) is irradiated. A + primary diffracted light (c) and a - primary diffracted light (d) are superposed and made to interfere with each other through the mirrors 131, 132 and 133, the mirror 17 and the mirror 15, and its intensity is measured by a photodetector 22 by varying a path difference of both of them. Also, the path difference is varied by a vibration of the mirror 17. When the path difference is varied, an intensity of an interference light of the + or - primary lights (c), (d) is varied like a sine, therefore, when its maximum value and minimum value are measured, a standing wave ratio of the elastic surface wave is derived from a specified expression. In this case, an oscillator 5 is brought to AM modulation by a modulating signal source 4, and an intensity of a modulated synthesized light is detected 3 by using an output of the same signal source 4 as a reference signal, therefore, an S/N ratio is improved.

Title: Aspect ratio conversion lens
Inventor: NAKAYAMA KATSUYUKI
IPC: G02B13/08
Filed: 1992-04-07
Abstract: PURPOSE:To easily obtain image pickup signals which have a current aspect ratio and a wide aspect ratio by rotating a rotary lens and setting the aspect ratio of a subject image. CONSTITUTION:A convex lens 5 and a concave lens 6 convert the subject image into a vertically long image while mutually increasing their curvatures. In this case, the longitudinal length of the subject image is increased by the convex lens 5 and the lateral length is decreased by the concave lens 6. The subject image photographed for wide-angle monitoring is therefore obtained for wide-angle monitoring on a CCD image pickup element through an anamorphic lens. Then the concave lens 6 is rotated by 90 or 270 deg.C in plane perpendicular to the optical axis O and then the convex lens 5 and concave lens 6 cancel their curvatures mutually, so that the image pickup signal with a 4:3 aspect ratio can be obtained.

Title: Network band display method for audio device
Inventor: KOYAMA YOSHIHIDE
IPC: G01H3/00
Filed: 1993-04-19
Abstract: PURPOSE:To accurately recognize a network band by displaying plural network bands determined by cutoff data set by analyzing frequency characteristic by bar graphs at every low frequency band, and displaying the frequency characteristic simultaneously. CONSTITUTION:The bar graphs A, B, C and D representing the network bands in accordance with the cutoff data and the frequency characteristic E of a sound outputted from a speaker are displayed. For-example, when the cutoff frequency in the high frequency band of the network band of a woofer is changed from 1.6kHz to 400Hz, the length of the bar graph B of LOW is changed from a position shown in dotted lines to a position shown in solid lines in real time. In the case of no woofer, it is discriminated whether or not it is the MID range for intermediate frequency band of a change value. In the case of the MID range, the network band of the MID range is changed corresponding to the change value, and also, the length of the bar graph C representing the network band displayed on a display part is changed.

Title: Pneumatic tire with excellent wandering property
Inventor: KAJIMOTO KATSUHIKO
IPC: B60C11/11
Filed: 1980-08-22
Abstract: PURPOSE:To improve the wandering property during running over rutted road by a method wherein the rigidity of the tread-in side groove wall in the tire is made higher than that of the kick-off side groove wall. CONSTITUTION:Lateral grooves 3 are cut in to a tread 2 at the marginal regions of the both sides of the tread 2. Let the groove wall of the lateral groove, the side of which contacts with the ground ahead the other side of the lateral groove during the rotation of the tire, be the kick-off side groove wall 4a. Let the groove wall of the lateral groove, the side of which contacts with the ground after the other side, be the tread-in side groove wall 4b. The angle beta between the tread-in side groove wall 4b and the tread surface 2 is intended to be larger than the angle alpha between the kick-off side groove wall 4a and the tread surface 2. And yet the rigidity of the groove wall 4b is made higher than that of the groove wall 4a. Due to the structure as described above, the shearing forces are generated at the right and left marginal regions of the tread with the rotation of the tire. When the tire runs over a slant such as a rut or the like, because the ground contact lengths at the right and left marginal regions are different, the shearing forces generated at the regions are different, resulting in generating the turning moment. Because said turning moment has the direction to run up the slant, the improvement of the warndering property of the tire is resulted.

Abstract: PURPOSE:To prevent any disconnection of a filament for an emitter to which a sample is attached by providing the measures of controlling the current of the emitter, and thereby automatically intercepting the emitter current when a probe is drawn from an ion-source room. CONSTITUTION:A conductive strut 9 at the end of a probe 4 is provided with a filament 3. In analysing, an emitter 2 with a sample attached to that is mounted on the conductive strut 9. In addition to that, a probe 4 is provided with a groove 8.

Consequently, when the probe 4 is drawn from the ion-source room 1 current is not supplied to the filament 3, and only when the probe is inserted in the ion-source room 1 current is supplied to the filament 3. Therefore any disconnection of the filament 3 can be obviated and the life of the filament 3 can be lengthened.
