Title: Boosting circuit; semiconductor storage provided with boosting circuit
Inventor: FURUYA KIYOHIRO
IPC: G11C11/407
Filed: 1990-11-21
Abstract: PURPOSE:To perform a readout operation and a write operation at high speed by a method wherein, when a word line is driven by being boosted to a potential at a power-supply voltage or higher, the word line is driven at the power-supply voltage or higher and at high speed by using a bipolar transistor whose gain is high. CONSTITUTION:A source for a MOSFET 2 is connected to a gate for a p-type MOSFET 3; its source is connected to a base for an npn-type bipolar transistor 4 for word-line drive use. An emitter for the transistor 4 is connected to a word line WL; it is grounded via a MOSFET 5 whose continuity is controlled by a clock signal phiR. In this case, at transistors having the same area, the word line is charged by the bipolar transistor whose current-amplification factor is larger than that of the MOSFET. Consequently, even when the capacity of the word line is increased by a high integration, the word line can be driven at high speed and at a power-supply voltage or higher. Thereby, the speed of the access time can be made high.

Title: Character processor
Inventor: YOSHIDA MASAYUKI
IPC: G06F3/12
Filed: 1988-12-19
Abstract: PURPOSE:To output data without any limitation of the number of characters by providing a memory for storing the data, deciding whether or not the data can be stored in the specific memory, and controlling a storing method. CONSTITUTION:In a step St3, data in vector form which is multiplied by an enlargement/reduction rate determined in St2 is stored in the memory. From the states of two flags, it is decided whether or not data consisting of a specific number of characters can be stored in the memory. When the 1st flag is on, the whole data can not be stored in the memory and the data needs to be divided. When the 2nd flag is on, the flag means that data which can not be stored is left. In St4 - St6, the stored data is converted from the vector form to a dot form and when the 2nd flag is on, the process returns to the St3 to repeat the operation. When no data is left, the process is finished and thus the data can be outputted without any limitation of the number of characters.

Filed: 1990-11-23
Abstract: PURPOSE:To detect the deterioration of a developer, by operating the density of a document on the basis of a picture signal, and comparing it with a reference value set previously. CONSTITUTION:A comparison portion 534 of a toner deterioration detecting means 53 compares the average density operated at an operation portion 532 with a reference value set previously, and decides if a toner has deteriorated or not. That is, the less the average density is, the less the development counter inside toner is, and it follows that the toner has stayed in the development counter, and its stirring time has become long, and the toner has deteriorated. And, when it is decided at the portion 534 that the toner in the development counter has deteriorated, the detecting means 53 outputs a deterioration signal to a toner deterioration preventing means 54, and toner deterioration is prevented.
