Title: System for correcting electronic timepiece
Inventor: SHIMIZU ATSUKO
IPC: G04G5/02
Filed: 1984-10-23
Abstract: PURPOSE:To accurately and easily perform the correction of time, by performing correction when at least two or more of correction pulses corresponding to the rotary speed of a correction switch were outputted. CONSTITUTION:When a rotary bezel is rotated at a medium speed, one pulse of a signal (a) is outputted at first and a signal (b) is subsequently outputted by one pulse on the basis of an input pulse A. that is, the signal (b is outputted from the second time of the input pulse A. Because the signal (b) is inputted to the C-input terminal of D-FF33A of a 15-min quick feed control part 31 as a clock, D-FF3A takes in a high level signal in synchronous relation to the falling of the first time signal (b) and the Q-level thereof comes to a high level. Because the Q-output of D-FF3A is supplied to an AND gate 34A as a gate control signal, the pulse on the after the second time signal (b) is outputted from the AND gate 34A. By this method, quick feed due to the erroneous operation of a correction switch is prevented.

Filed: 1983-11-26
Abstract: PURPOSE:To enable to perform a quick heating and a quick cooling on a semiconductor wafer at an equal temperature by a method wherein the shape of a plate-shaped support consisting of a metal material or a graphite material, whereon the semiconductor wafer is placed, is formed flatly in the wafer placing surface thereof, thicker in the peripheral parts of the wafer on the back surface thereof and thinner in the central part thereof by forming a recess in the back surface. CONSTITUTION:A wafer support 11 is made of a metal plate or a graphite material and the surface thereof is flatly formed in order to enable the metal of the wafer 1 to fittingly contact thereto. However, the back surface of the support 1 is not formed flatly. That is, the back surface is formed in the same thickness as that of other parts in the peripheral parts of the wafer 1, but is formed thinner in the face corresponding to the central part of the wafer 1 by forming a recess in the face. According to such a method, when the wafer 1 is abruptly heated and cooled, the temperature distribution of the wafer 1 becomes uniform in the peripheral parts and the central part. As a result, no dispersion generates in the characteristics of each chip section in the inner face of the wafer 1.

Abstract: PROBLEM TO BE SOLVED: To improve operability at the time of reproductino by providing a rewriting means rewriting a management area so that the index numbers of respective pieces of data are changed in accordance with priority which is set by a priority setting means. SOLUTION: When CPU 32 judges the change of priority by an input signal from an operation part 50, it reads data stored in the management area (TOC) 9b of a flash memory 9. When priority is changed, CPU 32 drives a priority setting part and changes the priority value of pertinent sound data in TOC information of data which RAM 34 stores. The values of the priority and the index numbers of respective pieces of sound data which belong to sound data changed by driving the priority setting part and which are stored in a file are read. The index numbers of respective sounds are rearranged in order from the largest value of priority in accordance with a rule. CPU 32 drives the TOC rewriting part and rewrites TOC information.

Title: Line feed method for document processor
Inventor: GUNJI KATSUE
IPC: G06F17/21
Filed: 1990-08-24
Abstract: PURPOSE:To improve the operating performance and the sentence producing efficiency by setting automatically the space codes up to a point right before the position of the head character of the next line at application of a period and a line feed together with a cursor displayed at the position of the head character of the next line, and inputting the characters at the position where the cursor is displayed. CONSTITUTION:When a line feed mark 1b is pointed on a prescribed line, a fact whether a period 1a is inputted right before the line feed or not is discriminated. If so (both period and line feed applied), the digit position (the n-th digit) of the head character is decided on the relevant line. Then the space codes are automatically set up to the digit position from the head of the next line and at the same time a cursor 2 is displayed at the digit position next to the preceding digit position on the next line. Then the characters 1c are inputted at the digit position. Thus it is not required to move the cursor 2 up to the head character position of the next line at application of a period and a line feed. Then the operating performance and the sentence producing efficiency can be improved for a document processor.
