Title: Radical converting device
Inventor: ATSUMI HIROKI
IPC: G06F17/22
Filed: 1988-12-27
Abstract: PURPOSE:To attain the simple input of desired KANJI (Chinese characters) even in the case the Japanese reading ways of KANJI and radicals are not known by a KANJI/radical conversion table in addition to a normal radical/ KANJI conversion table. CONSTITUTION:A key input part 12 serves as a key input device to input the document data and various commands and contains a radical conversion key AK. When this key AK is operated, a CPU 11 retrieves a KANJI/radical conversion table memory 17 based on the KANJI equivalent to two characters which are previously designated and converts each designated KANJI into its component radicals. Based on these radicals, a radical/KANJI conversion table memory 16 is retrieved and each designated KANJI is converted into another KANJI consisting of the combination of its component radicals. This converted KANJI is displayed as a candidate. Thus it is possible to simply input the desired KANJI just by designating the prescribed number of KANJI equal to each radical forming the KANJI whose Japanese reading way is not known.

Abstract: PROBLEM TO BE SOLVED: To prevent the oxidation of Pd films formed on the terminal parts of an external electrode by forming a hydride by leaving as it is a lead frame on which a hydrogen absorbing metallic layer is formed in a hydrogen atmosphere before one heat treatment which is performed in each process. SOLUTION: Plated Ni layers 2 and plated Pd layers 3 are successively formed on the terminal parts 1 of the external electrode of a lead frame 1. Then a palladium hydride is formed as a first hydride by leaving the lead frame as it is in a hydrogen atmosphere. After a semiconductor chip 5 is stuck to the supporting plate 1b of the lead frame with an adhesive 6 composed of a conductive epoxy resin, the adhesive 6 is thermoset through heat treatment. During the course of the heat treatment, the oxidation of the plated Pd layers 3 can be prevented, because the palladium hydride formed on the lead frame 1 is pyrolytically decomposed and forms a reducing atmosphere by discharging a hydrogen gas.

Filed: 1987-12-28
Abstract: PURPOSE:To keep secrecy by prohibiting the output of the information of a dialed number on a display device at the time of generating data by a switch monitoring part. CONSTITUTION:A functional switch monitoring part 4 checks a functional switch 12, and when the functional switch 12 is turned on, a flag is set.

IPC: H04N5/10
Filed: 1987-12-28
Abstract: PURPOSE:To attain sure recovery output of a horizontal synchronizing pulse by providing an oscillator driven by a color burst and a frequency divider counting the oscillated output and recovering the synchronizing pulse and applying stable horizontal synchronizing pulse recovery independently whether a horizontal synchronizing pulse is included or not in a composite video signal. CONSTITUTION:When a composite video signal is inputted to a synchronizing pulse recovery circuit, a synchronizing separator circuit 1 detects the falling of a vertical synchronizing pulse and outputs its detection signal to a delay circuit 9. A burst gate pulse generating circuit 5 generates a burst gate pulse based on the inputted delay signal. A frequency divider 4 divides the clock oscillation output up to the horizontal synchronizing frequency and outputs a horizontal synchronizing pulse. In this case, the frequency divider 4 is initialized be an input signal of a generating circuit 5 to apply the pulse matching of the horizontal synchronizing pulse. Since the output of the frequency divider 4 is fed back to the generating circuit 5, even if the synchronizing separator output is sometimes missing, the horizontal synchronizing pulse is recovered and outputted stable.
