Title: Frequency division ratio switching method
Inventor: TOMOSAWA KIKUO
IPC: G06F9/46
Filed: 1991-10-28
Abstract: PURPOSE:To measure a period, while switching a frequency division ratio, and also, to eliminate a switching error of the frequency division ratio by switching the frequency division ratio to UP, in the case the period is below the upper limit valve of a prescribed range, and also, does not exceed the upper limit of the frequency division ratio, and switching the frequency division ratio to DOWN, in the case the period is above the lower limit value of the prescribed range, and does not exceed the lower limit value of the frequency division ratio. CONSTITUTION:A value after an (n) frequency division of a capture register at the time when an event is generated, is stored in a memo 1 (ST1). Subsequently, a value of the capture register at the time when the previous event is generated, stored in a memo 3 is subtracted from the value stored in the memo 1 and a period T is derived, and stored in a memo 2 (ST2). Next, whether the value of the period T stored in the memo 2 exceeds the upper limit value THH of hysteresis data or below its value, is decided (ST5), and in the case where the value exceeds, subsequently, whether its value is below the lower limit value THL or above its value, is decided (ST6). Thereafter, moreover, whether the period value T is the upper limit of the frequency division ratio or not (ST7), and in the case where its value is not the upper limit of the frequency division ratio, the frequency division ratio is switched to an UP side (ST8).

Title: Manufacture for semiconductor device
Inventor: KANEKO SEIJI
IPC: H01L21/265
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which an abnormal leak current does not occur in the semiconductor device such as transistors, etc., without causing crystal defects within a semiconductor substrate. SOLUTION: After an interlayer insulation film 100 is formed prior to lamp annealing, a lamp light absorption film 110 is deposited to thereafter lamp-anneal processing. Thus, lamp lights from an upper part of a semiconductor substrate in the lamp annealing are absorbed by the light absorbing film, and the lamp lights from a lower part of the semiconductor substrate are absorbed by the semiconductor substrate as it is. For this reason, the light absorbing film and semiconductor substrate are heated, and impurity ions are activated by radiant heat. As described above, since activation annealing is performed by use of the radiant heat, it is possible to reduce a difference in temperatures between an end of an activation region and an element isolation region, similarly to the case of using a diffusion furnace.

Abstract: PURPOSE:To enable secure detection by providing a pulse light emitting element and a light receiving element in a case and detecting the AC component of pulses of an output signal. CONSTITUTION:When the light emitting element 5 emits red light to a storage tank 1, the light receiving element 6 in the recessed part 4a of the case 4 detects a considerable quantity of reflected light when the level of granular body is A.

IPC: H01S3/06
Filed: 1991-11-25
Abstract: PURPOSE:To obtain the measuring instrument for a noise figure, which is exact and has high reproducibility. CONSTITUTION:A signal light source 2 generates a signal light for measuring gain of an optical fiber amplifier 4. A polarizer 8 allows a polarized light having a component in the direction orthogonal to the polarization direction of an amplified signal light to transmit through, in an output light outputted from an optical fiber amplifier 4 in accordance with an input of the signal light from the signal light source 2. Analyzing device 10, 14 determine power of an ASE by measuring the polarized light allowed to transmit through by the polarizer 8. In this case, since it is considered that a polarized light state of the signal light scarcely gets worse in the optical fiber amplifier 4, it is considered that a component of a non-polarized light in the output light, that is, only the ASE is allowed to transmit through selectively and can be measured. By utilizing a result of this measurement, power of the ASE can be determined in a state that a skirt part of the signal light is eliminated, and an exact noise figure NF value can be given.

Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To execute hand-over without interruption of a speech while suppressing current consumption and interference on a communication another party at the outside of communication. SOLUTION: A common control channel signal is extracted from each base station device by allowing an inverse spread section to apply inverse spread processing using a prescribed spread code to a base band signal from an RF section.

IPC: G01R31/28
Filed: 1986-12-27
Abstract: PURPOSE:To reduce testing cost, by feeding back the trigger pulse outputted from other electronic circuit to a certain electronic circuit. CONSTITUTION:When a selector 6 is set to an A/B side and a trigger pulse is inputted to the first circuit module 1, the trigger pulse A from the module 1 is inputted to the second circuit module 2 and the trigger pulse A' of the module 2 is inputted to the third circuit module 3.
