Title: Manufacture of fluorescent display panel
Inventor: AKIYAMA TOSHIYUKI
IPC: H01J9/227
Filed: 1989-09-29
Abstract: PURPOSE:To simplify wiring constitution and omit some of manufacturing processes of a fluorescent display panel by utilizing existing wiring for actuating a P-channel type thin film transistor(Pch-TFT) that constitutes the switching element of each picture element, and forming a phosphor layer on a picture element electrode via the Pch-TFT by electrophoresis method. CONSTITUTION:A picture element electrode 6 is connected to the drain electrode of a Pch-TFT 9 and a source electrode and a gate electrode switch the Pch- TFT 9 on when a negative voltage is applied to an opposite electrode 5, and then an current I is generated from drain electrode to source electrode and the picture element electrode 6 becomes negative with respect to the opposite electrode 5. Thus phosphor particles having positive metal ions attached to their surfaces are migrated to the picture element electrode 6 to form a phosphor layer. The current I is controlled by solution resisting components and the resisting components of the phosphor layer. Therefore, wiring constitution is simplified and also some of manufacturing processes of the fluorescent display panel can be omitted.

Title: Semiconductor integrated circuit
Inventor: SEZAKI ISAO
IPC: H01L27/10
Filed: 1989-09-28
Abstract: PURPOSE:To shorten a cycle time and to improve an operation speed by setting the ratio of a sampling period so as to be larger than that of a pre-charge period. CONSTITUTION:A circuit for making a ratio of pre-charge periods 15, 17 and sampling periods 14, 16 variable is used, and its output is inputted to a read-only memory (ROM). That is, in the case the pre-charge period 15 is set so as to be shorter than the sampling period 14 by a duty converting circuit 11, the sampling period 14 can be lengthened even by the same input block signal frequency. Also, in the case the pre-charge period 17 is set so as to be shorter than the sampling period 16, the pre-charge period 17 can be lengthened even by the same input clock signal frequency. In such a way, it does not occur that the upper limit of a frequency of a clock signal is determined by a longer time of the time required for pre-charge or the time required for sampling, and the semiconductor integrated circuit being advantageous to a high speed conversion is obtained.

Title: Aggregate recovery system
Inventor: YAMAZAKI MASAYASU
IPC: B02C21/00
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To provide an aggregate recovery system which can produce a coarse aggregate and a fine aggregate which is reduced in an amount of matters adhered thereto. SOLUTION: A solid such as concrete waste is ground and kneaded by a vertical grinding and kneading device to remove an adhesion component from the surface of aggregate as impalpable powder. At this time, the heat of hot air blowing from a blowing pipe of a main body causes good peel off of the impalpable powder due to a difference between the thermal expansion coefficient of the impalpable powder and that of the aggregate. The ground and kneaded concrete waste is classified into a coarse aggregate (5 mm or more) and a fine aggregate (less than 5 mm) by an aggregate recovery device 15 equipped with wire netting having a mesh size of 5 mm. As a result, the coarse aggregate and fine aggregate from which a mortar component and the like have been removed sufficiently can be obtained.
