Title: Abnormality-detecting apparatus of narrow-band oscillated excimer laser
Inventor: WAKABAYASHI OSAMU
IPC: H01S3/137
Filed: 1987-12-26
Abstract: PURPOSE:To enhance reliability by a method wherein an abnormality of a width or a shape of an oscillated laser beam is detected on the basis of an interference fringe generated by a monitor etalon. CONSTITUTION:The following are installed: a means 103 used to take out one part of an oscillated laser beam; a monitor etalon 401 used to monitor a taken- out laser beam, an abnormality-detecting means 400 used to detect an abnormality of the oscillated laser beams on the basis of an interference fringe 402 generated by the monitor etalon 401. That is to say, the interference fringe 402 generated by the monitor etalon 401 corresponds to an overlap of two or more waveforms displaced by an amount of a free spectral range; accordingly, when a width of the laser beam is expanded or its shape is distorted, contrast, maximum light intensity, minimum light intensity, light-intensity distribution and the like of the interference fringe 402 are changed. Accordingly, if the contrast of the interference fringe is monitored, a function equal to that to monitor the waveform or the width of the laser beam can be realized. By this setup, it is possible to detect the abnormality of the oscillated laser beam simply and with high accuracy.

Title: Method and device for information processing
Inventor: TSUNODA MASAMI
IPC: G10L15/00
Filed: 1990-11-29
Abstract: PURPOSE:To know the location of a device even where not visible to the operator because of being obstructed by any other object, by actuating buzzer etc. when sound information inherent in the device previously stored is fed, and thereby informing the operator of existence of the device. CONSTITUTION:If judgement is such that the fed sound information is identical to sound information which has been set as inherent in a certain device, a signal is emitted to inform that the two pieces of sound information are identical. In conformity to the signal, a CPU 1 gives a command to a buzzer I/F 3 so that a buzzer 4 goes. This eliminates such a problem that the user loses the location of device when it is used in an environment with other miscellaneous matters existing without order, which is likely in the current situation where information processing device is embodied small.

Title: Power supply control integrated circuit
Inventor: HIASA NOBUYUKI
IPC: H02M3/28
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To improve efficiency by reducing switching loss in light load. SOLUTION: A triangular wave oscillation circuit is composed of transistor MP4 and MN3 for charging and discharging timing capacitors C-CT, comparators comp1 and comp2 for determining the upper/lower-limit values of an oscillation waveform, and an RS flip flop RSFF, and others composed of a circuit for determining a charge/discharge current. An amplifier FB-A outputs a voltage according to a load level. A multiple-input amplifier RT-A performs control so that a voltage that is lower out of the output voltage of an amplifier FB-A and an internal reference voltage Vdd (2.5 V) becomes the terminal voltage of a timing resistor R-RT, thus resulting in a constant charge/ discharge current being determined by the internal reference voltage Vdd (2.5 V) and making constant an oscillation frequency in a normal mode.  In light load, the charge/discharge current corresponds to a load level, and the oscillation frequency decreases according to the decrease in load, thus improving efficiency due to the decrease in the number of switching.

IPC: H01L21/316
Filed: 1992-11-20
Abstract: PURPOSE: To manufacture a die which is hardly contaminated, extending into an electrically active region by forming a protection film which stops a dielectric layer from being peeled off and a contaminant from reaching the electrically active region of the die. CONSTITUTION: A die 40 has a stitch protective ring 190 which nearly stops the peeling or contamination of a BPSG layer which starts nearby an edge part 41 of the die from reaching an electrically active area 45 and a bond pad. Then a sidewall spacer is formed in a protective ring opening and made hard to peel off the flank of the protective ring opening. The protective ring opening is formed of more than one linear segment of approximately 3.0 μm in length. Consequently, a flattened dielectric layer can be formed without exerting any adverse influence on a diffusion junction part or causing the dielectric layer in the semiconductor die to peel off.

Title: Antistatic method and antistatic device used in same method
Inventor: MATSUDA KYOJI
IPC: H05F3/04
Filed: 1989-12-22
Abstract: PURPOSE:To prevent charge of the surface of a measuring object by supplying inert gas ion of low energy to the surface of the measuring object. CONSTITUTION:In a surface analytical method, a charged ionized inert gas is flowed into the surface of a charged measuring object in parallel with the surface or at a fine angle of incidence with low energy. In other words, in case the surface of a measuring object is negatively charged, when a positive ion of positively ionized inert gas passes on the surface of the measuring object, the positive ion takes away the negative charge on the surface of the measuring object to be neutralized and becomes a neutral atom. Reversely, when the surface of the measuring object is positively charged, negatively ionized inert gas is made to flow on the surface of the measuring object. It is thereby possible to prevent simply and certainly the surface of the measuring object from being charged, so that an accurate spectrum can be obtained.
