Title: Optical semiconductor element
Inventor: UJI TOSHIO
IPC: H01S5/00
Filed: 1984-07-20
Abstract: PURPOSE:To enable a single element to directly control the light output level in accordance with the light input, by providing a region in which the high-frequency impedance varies in accordance with the amount of incident light in a part of the path of high-frequency current. CONSTITUTION:An n type InP layer 42, an n type InGaP luminescent layer 13, a p type InP layer 43 and an n type InGaAsP layer 44 are formed on an n type InP substrate 41, and a p<+> region 45 is formed. Regions 14 having deep levels at high densities are selectively formed in portions of the layer 43 which are in the vicinity of the interface between the layer 43 and the layer 13. When a forward pulsed voltage is applied to this element, the high-frequency current component also flows outside a liminescent region 12. When there is no light input Pin, deep levela are formed in the regions 14 at high densities. Therefore, the junction capacitance between the layer 43 and the layer 13 is relatively smal, so that the light output Pour has relatively short rise time. When the input Pin is increased, the junction capacitance increases, and the rise time of the output Pour becomes relatively long. When the pulse width is set at, e.g., about 2ns, the output Pout lowers ad the input Pin increase. In this way, the light from the LED can be controlled.

Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To obtain a filter having plural desired spectroscopic characteristics and can easily be handled by providing a multilayer film having plural spectroscopic characteristics on one base plate. SOLUTION: The multlayer film having plural spectroscopic characteristics is provided on one base plate 2. Namely, in the case of constituting an optical filter 1, one transparent base plate 2 is divided into three regions A to C, and several layers of film (vapor-deposited film) are formed by a vacuum deposition method in the respective region A to C so as to obtain three filters 1a to 1c, which are made one filter 1 as a whole. The filter 1b has the spectroscopic characteristic different from the filters 1a and 1c. It does not matter whether the spectroscopic characteristic of the filters 1a and 1c is the same or different, but it must be the characteristic in accordance with need.  By such constitution, the plural desired optional spectroscopic characteristics are obtained by one filter without using plural filters by changing the characteristic of the multilayer film formed by the vapor deposition.

Filed: 1980-10-28
Abstract: PURPOSE:To form gate electrodes highly densely without forming overlapping by performing dry etching so that the convex part of a poly Si film which is to become the second electrode gate is etched faster than the concave part. CONSTITUTION:A first gate insulating film 12 is uniformly grown on a semiconductor substrate 1. Thereafter the first gate electrode 13 is formed. Then the part of the film 12 other than the part directly beneath the electrode 13 is removed, and a second insulating film 14 is grown. Thereafter a poly Si film 15' which is to become the second gate electrode is deposited on the entire surface. Then the dry etching is performed on the film 15'. In this case, the convex part of the film 15' is etched faster than the concave part. Finally, the convex part is removed and the concave part remains and becomes the second gate electrode 15. As a result, the electrode 13 and 15 are not overlapped and are arranged approximately on the same plane. Therefore, wires are not broken even though a wiring layer is formed thereon, and the electrostatic capacity between the gate electrodes is not increased.

SOLUTION: A control stage 1 receives a bit frequency input and signal and a control signal I, (e), and outputs a complementary logic signal or a logic level outputted to output terminals A, B, which is inverted by 1st and 2nd inverter stages 2, 3. As a result, the inverted logic signals obtained at output terminals E, F are given to an analog level difference reduction stage 4, in which the analog level difference is reduced and the output of an I/F device is switched to a high impedance. An output stage 5 being the next stage inputs the signals at the terminals E, F and the signal from the reduction stage 4 and decides a current to be charged/discharged to/from an output capacitor and outputs an output signal XXX through balancing.  Thus, the information processing with a storage device is attained as the I/F device in compatible with the tri-state without deteriorating an analog signal.

IPC: G06F15/167
Filed: 1989-06-14
Abstract: PURPOSE:To improve the reliability of a data processor by preparing a refresh signal detecting circuit and having an access to a common memory after a signal is validated. CONSTITUTION:A main CPU 1 performs various initial processes right after the application of a power supply and at the same time each master unit 4 also carries out an initial process. If an access is given to a common memory 3 in the initial process, the unit 4 checks the signal received from a refresh detecting circuit 5 and detects the validity of a refresh signal of a system common bus 2 to report this detecting result to other units 4. Then the unit 4 stops the access to the memory 3 if the checking result of the circuit 5 is not satisfactory. The access to the memory 3 is held until the refresh signal is validated. Thus the waiting time is secured at a time point right after the application of the power supply. Then an access is surely given to the memory 3 that started a refresh action. As a result, the reliability of a data processor is improved.

Abstract: PURPOSE:To detect short-circuit closing quickly and accurately and to make it possible to alleviate the stress due to the short-circuit current as a result by detecting the level and the frequency of the primary current of a transformer. CONSTITUTION:The current flowing through the primary side of a transformer 3 is rectified in a rectifier 5 which is connected through a current detector 2, and the current is detected. In a frequency detecting means, the low level of the current which is rectified in the current detecting means is cut in a comparator 7, and the current is converted into the voltage signal corresponding to the frequency in an F/V converter 8. The signal is compared with the specified preset value in a comparator 9. Thus, the frequency of the primary current of the transformer is detected. At this time, a voltage corresponding to the value twice the voltage without a load input is set in a setter S2. The current which is rectified in the current detecting means is compared with the specified preset value in a comaprator 13 in a level detecting means. Thus, the magnitude level of the primary current of the transformer is detected. At this time, the voltage corresponding to the no-load input level is set in a setter S3.
