Title: Level compressor for digital signal
Inventor: KASUGA MASAO
IPC: H04B14/04
Filed: 1979-07-03
Abstract: PURPOSE:To remove nonlinear distortion based upon an excessive input by level- compressing a digital signal in case that a digitized code pattern of not less than a fixed level is input. CONSTITUTION:A code pattern of a digital signal arriving from input terminal 1 is supervised by peak detecting circuit 3 and level detecting circuit 6 and when a digital level of not less than a maximum level that the device can process arrives, attenuation characteristics are provided to multiplier 9 in accordance with the value of the excessive level. The attenuation characteristics are given by coefficient unit 8 composed of ROM in accordance with the excessive level. Then, the input digital signal is delayed by delay circuit 2 by the time that the circuit requires for attenuation and since the attenuation is carrier out by fixed time-constant circuit 4, the excessive input signal can smoothly be attenuated, so that an overflow can be prevented.

Title: Trace information output system
Inventor: NARITA KOTARO
IPC: G06F11/28
Filed: 1990-03-30
Abstract: PURPOSE:To output trace information with an executive program without recompiling neither relinking by designating a trace instruction and a trace program at the time of executing the executive program. CONSTITUTION:The trace mode, the trace instruction, and a correspondence table between the trace instruction and a trace program name are inputted to and stored in a trace information input means 1. If the trace mode is stored and an execution instruction coincides with the trace instruction at the time of extracting the execution instruction, a trace program executing means 2 reads out the trace program in accordance with the correspondence table to execute it. A trace information output means 3 edits trace information obtained by the trace program executing means 2 in accordance with trace information editing information to output the result. Thus, trace information is outputted with the executive program without recompiling neither relinking.

IPC: G02B6/42
Filed: 1982-05-21
Abstract: PURPOSE:To obtain good coupling of a single mode optical fiber and a semiconductor laser, by providing a medium part consisting of the same substance between a semi-spherical lens of the tip and the end face of an optical fiber. CONSTITUTION:A semi-spherical lens 2 whose radius is R is fitted through a medium part 6 to a tip part 5 of a fiber consisting of a core 3 and a clad 4. The medium part 6 consists of a material having an equal quality to the semi-spherical lens 2, its length is denoted as zeta and a distance between a laser chip 1 and the fiber tip is denoted as (z). A distance between the fiber tip and a (z) axis, and inclination from the (z) axis are denoted as dy and phiy, as a symbol for showing a position shift of the laser chip 1 on a (yz) plane and a fiber 7, and as a result of an experiment by varying a numerical value of said symbol in various ways, it becomes clear that the maximum coupling efficiency is obtained when the radius R is within a range of 10<=R<=100(mum) and the length zeta of the medium part is 5.6R -22<=zeta<=154R-5(mum).

IPC: A47J37/08
Filed: 1981-06-01
Abstract: PURPOSE:To enable to produce a uniform scorch pattern constantly irrespective of changes in conditions, by a method wherein a main body comprising a roasting chamber is provided with a photoelectric converting part, and a heat source is controlled by detecting a reflectivity of light proportional to the scorch pattern on the object to be roasted by the photoelectric converting part. CONSTITUTION:When putting a slice of bread 5 on a net 6 and roasting it by passing an electric current to a heater 7, the bread 5 before being roasted has a high reflectivity, the reflected light of a tungsten bulb 10 used as a light source is focused by a focusing lens 13 and is received by the photoelectric converting part 15. A capacitor 19 is charged by an output from the converting part 15. When a switch 17 is changed over to a terminal c, an electric current is supplied to the heater 7 to start roasting, and the reflectivity is lowered as the scorch pattern on the bread 5 is thickened. When the output from the converting part 15 coincides with an output set by a variable resistance 21, the supply of current to the heater 7 is cut off by an output from a differential amplifier 23, and the capacitor 19 is discharged by the turning-on of the switch 22 to obtain a reset condition.

Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To set an optimal measurement delay time quickly by operating a delay time to be set on the module side from the measurement data of an element to be inspected on the module side and a measurement designation time thereby obtaining a variation of output signal with time easily. SOLUTION: A continuous measurement designating section 12 sets a zero delay time on the test program module side and designates measurement of an element to be tested DUT continuously. A transient response recording section 14 records the measurement data of the DUT on the module side, along with the measurement designating time of a timer, according to a measurement designation from the continuous measurement designating section 12 and correlates the measurement data with the time. A delay time operating section 16 operates a delay time to be set on the module side from the recorded measurement data and the measurement designating time. Subsequently, a transition is made to a mode for resetting the delay time set value on the module side to an inherent response delay time of DUT and measuring the DUTs one after another.  According to the method, an accurate measurement can be attained quickly.

Title: Corrector for fluorescent camp flicker
Inventor: MIYATA MASANORI
IPC: H04N9/04
Filed: 1990-03-30
Abstract: PURPOSE:To decrease fluorescent lamp flicker by writing the output of a camera in a digital memory and processing the output for each field decided according to relation between the frequency of the intensity change of a light source and the video field frequency of the camera equipped with a solid-state imaging device. CONSTITUTION:The video signal of one field is written in a memory 3 for every three fields. This is dealt with by dividing the frequency of a vertical synchronizing signal from a synchronizing separator circuit into 1/3 within a control circuit 7. Namely, when an A4 field is written in the half of the digital memory 3, the data of following three fields is written in the remaining digital memory 3 at the timing of B6 fields. In this way, by selecting one field for every three fields, the output levels of the video signals in one selected field are almost equal, and therefore, even when outputting this signal, there is no influence of flicker. Thus, the fluorescent lamp flicker can be decreased by simple control.

Abstract: PROBLEM TO BE SOLVED: To output reproducing pictures continuously even when a tape running direction is reversed. SOLUTION: At the time of reversing a tape running direction in the process of reproduction, the updating of pictures by a picture output part 105 is stopped and a tape is fed to an instructed direction after a mechanism is moved by calculating the target address made to be a retrieval target in a target address calculating part 107 while extracting addresses on the tape by an address information detecting part 106, by returning the tape to a direction opposite to the instructed direction to count capstan FGs in this period with a capstan FG counting part 109 and by calculating the number of target counts to be the retrieval target with a number of traget counts calculating part 110.  At this time, comparisons between the target address and current address are continuously performed in an address comparing and discriminating part 108 and comparisons between the number of target counts and numbers of current counts are continuously performed in a number of counts comparing and discriminating part 111. Thus, a control part 113 realizes the reproducing of continuous pictures even at the time of reversing the tape running direction by allowing the part 105 to perform the updating of pictures with these results.
