Title: Timepiece presenting hour/minute figure separately
Inventor: NAKAMATSU YOSHIRO
IPC: G04B19/00
Filed: 1994-04-14
Abstract: PURPOSE:To enable a timepiece to display figures of hour and minute separately and reduce discrepancy by arranging the figures of hour and the figures of minute concentric and providing a display section to be matched with the figure of hour and the figure of minute. CONSTITUTION:Hour figures of 1 to 12 are arranged in an inner circle and minute figures of 1 to 60 in an outer circle in the same circular shape. A part 7 is provided at a short hand 6 to cover the minute figures and a window 8 for viewing the hour figures 2 and a pointer 9 are arranged. A hour figure cover part 10 of a long hand 5 is shaped in a sector and a pointer 11 is made to stick out at the center thereof. A center part 9 of the short hand 6 indicates the hour figures while the tip of the long hand 6 indicates the minute figures. With such arrangement, the long hand indicates minute while a broad part 10 of the long hand covers the hour figures so that the minute figure alone is indicated while none of the hour figures is read out. This enables a user to read minute directly without training hour to read an analog clock, hence eliminating judgment from the shape and the angle of the hands.

Abstract: PURPOSE:To prevent one-sided abutting between sides of a york and a spider by providing a means for restraining expansion of the part, on the side of the spider, of the york of which one end is inserted in and connected to a shaft member. CONSTITUTION:A propeller shaft 1 is provided with a tubular shaft member 2, and a york 3 which has a higher heat expansion rate than that of a spider 5 and of which one end is inserted in and connected to the shaft member 2.

Filed: 1990-04-26
Abstract: PURPOSE:To manufacture a semiconductor device in which an interval between a gate electrode and a high concentration layer is widely formed and an increase in a gate resistance can be suppressed by forming the high concentration layer by ion implanting with a mushroom shape gate electrode extended widely to a drain side as a mask. CONSTITUTION:After the entire surface is covered with a gate electrode metal 31', a photoresist 4 is patterned by photocomposing technique to form an offset structure in which a drain side is widened. Then, with the photoresist 4 as a mask a a gate electrode metal 31 is anisotropically etched to form a gate electrode 3. Thereafter, with the electrode 3 as a mask an n<+> type GaAs layer of high concentration layer is formed by ion implanting. Since the shape of the gate electrode is formed in a mushroom shape extended widely at a drain side, an interval between the high concentration layer formed by ion implanting with the electrode as a mask and the gate electrode can be increased to provide high breakdown strength.

Title: Steering control device for autonomous traveling vehicle
Inventor: KAMIMURA KENJI
IPC: G05D1/02
Filed: 1990-04-26
Abstract: PURPOSE:To prevent the steering control device from lossing the sight of a reference point for a long time by changing a vertical scanning angle only by a proposed angle in each scanning cycle at the time of lossing the sight of a light reflecting means arranged on the reference point, and detecting reflected light from the undetected light reflecting means again. CONSTITUTION:Plural reference points are set up around a working area and reflectors 6a to 6d consisting of light reflecting means provided with reflecting faces for reflecting incident light to the incident direction are arranged on respective reference points. An optical beam 2E scanned from an optical scanner 2 in the direction of the arrow 29 is successively reflected by the reflectors 6a to 6d. When the reference point can not be detected in a forecasting azimuth to be detected, the projection angle of the beam 2E is changed in each proposed angle with short intervals in the forecasting azimuth for detecting the reference point in the succeeding scanning to search the undetected reference point, so that even when the reference point is lost sight of, the reference point can be automatically searched. Consequently, the reference point can be prevented from being lost sight of it for a long period.

Title: Microwave low noise amplifier circuit
Inventor: HARA SHINJI
IPC: H03F3/60
Filed: 1992-04-30
Abstract: PURPOSE:To optimize the noise characteristic and input matching by loading a capacitor between a gate electrode and a source electrode and loading an inductor between the source electrode and a ground electrode. CONSTITUTION:A capacitor 5 is loaded between a gate electrode 2 and a source electrode 4 and an inductor is loaded between the source electrode 4 and a ground conductor 24. The effects such as approach between a source reflection coefficient for input matching and a source reflection coefficient for minimum noise, low input impedance, low equivalent noise resistance and increase in stability index or the like are obtained by addition of the capacitor. Since the inductance required for the input matching circuit is reduced, the loss of the input matching circuit is reduced, Furthermore, the noise characteristic and the input matching are simultaneously optimized by the reduction in the noise equivalent resistance.

Title: Secondary electron multiplier and photo-electron multiplier with same secondary electron multiplier incorporated
Inventor: KUSHIMA HIROYUKI
IPC: H01J43/22
Filed: 1989-04-28
Abstract: PURPOSE:To obtain a secondary electron multiplier and a photo-electron multiplier which are highly efficient by correcting the orbits of secondary electrons emitted from dynodes in the first stage, and thereby enhancing a carry-over factor over to dynodes in the second stage. CONSTITUTION:In groups 71 through 7n of dynodes, the dislocation S between the end sections 9a and 9b of an upper and a lower stage shall be set to be roughly 2/5d as usual in the second stage 72 through the (n)th stage 7n wherein d represents a dynode pitch. Only the dislocation S between the first stage 71 and the second stage 72 shall however, be set to be +1/5d<S<-1/5d by the method as described above in such a way as to be sufficiently smaller than 2/5d. This results in the characteristics of an electron carry-over factor as shown by a curve in the figure wherein the carry-over factor eta is roughly 80% representing the maximum when the dislocation S is equal to zero, eta will roughly be 60% representing the minimum when S is equal to 1/2d, similarly eta will roughly be 65% when S is equal to 2/5d, and eta will roughly be 72% when S is equal to 1/5d. This would allow an inequality of +1/5d<S<-1/5d to be maintained in order to obtain the excellent carry-over factor.

Title: Device and method for evaluating reliability of metal wiring and/or recording medium with program for reliability evaluation of the metal wiring stored therein
Inventor: SASAGAWA KAZUHIKO
IPC: G06F17/50
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To estimate void formation and burnout fault by numerical simulation using EM damage control parameters of metal wiring. SOLUTION: In a numerical simulation, metal wiring is divided into elements. The distribution of current density and temperature is obtained through numerical analysis (S304). An atomic flux divergence AFDgen of each element is calculated by using the distribution and the constant (S306) of the physical property of a material being determined by an acceleration test in advance (S308). Volume reduction (S312) per calculation step in the simulation is given by multiplying the volume of each element, time corresponding to one calculation step, and atomic volume corresponding to the calculated AFDgen (S310). Based on the amount of reduction for the volume, the thickness of each element is reduced (S314). In the element where the thickness has been reduced, that a void is formed is indicated. Numerical analysis of the current density and temperature distribution in the metal wiring is performed again, while taking the thickness of each element into consideration (S304). Then calculation is repeated.
