Title: Preparation of active carbon
Inventor: YAMAGUCHI TOKUJI
IPC: C01B31/08
Filed: 1989-08-14
Abstract: PURPOSE:To simply and inexpensively prepare good active carbon from coal by mixing finely ground caking coal with a specific finely ground non-caking coal, press-molding the mixture, carbonizing the molded products, crushing the carbonized products into even size granules and subsequently activating the granules. CONSTITUTION:Finely ground caking coal is mixed with 20-70wt.% of finely ground non-caking coal having a volatile content of >=45% (d, a, f,) and subsequently press-molded. The molded products as such or after crushed to adjust the granule sizes are carbonized in a chamber oven type carbonization oven, crushed for the uniforming of the granules and subsequently activated to provide the objective active carbon. By the method described above, the mechanical strength of the non-caking coal mainly comprising brown coal having >=45% (d, a, f,) of volatile contents is improved and the melting characteristics of the caking coal are utilized without lowering the melting characteristics by oxidation as in conventional techniques, thereby forming networks having high mechanical strengths in the caking coal and providing a carbonized product capable of being readily activated.

Abstract: PURPOSE: To make shifting operation without separating hand from the grip of a steering bar and enhance the easiness in works by locating a shift lever near the grip. CONSTITUTION: Cam plates 16, 17 fixed to the two ends of a shaft 14 are rotated at certain angle intervals by moving a shift lever 12. Thereby operational arms 18, 19 are reversibly swung through contacting pieces 18a, 19a which contact with the peripheries of the cam plates 16, 17, and one of the operating wires 20, 21 connected with the arms 18, 19 is tracted while the other is slackened. Thereby it is made practicable to operate a transmission installed on the machine body side. Because located near the grip of a steering bar 10, the shift lever 12 can be handled without separating hand from the grip. This allows stabilizing the working attitude, enhancing the easiness in works, and ensuring the safety of the operator.

Title: Library system
Inventor: IWATSUJI ICHIRO
IPC: G06T1/00
Filed: 1994-09-02
Abstract: PURPOSE: To obtain a system which is high in operability and extensibility and facilitates operation management by connecting plural units of library devices having the same functions with communicating means and constituting these devices so as to commonly possess information. CONSTITUTION: Videos and audios are inputted from a video and audio source 5 via a signal line 7 to a computer body 1. On the other hand, the command for starting video recording and sound recording of the videos and audios inputted from an operation input section 2 is processed by the body 1 to take the videos and audio into the body 1. The video and audio signals are subjected to compression processing and are then stored in a memory device 4. Since the information is commonly possessed between the respective library devices by the communication (LAN) signal line 8, the commonly possessed information (the compressed information of the videos and sounds stored in the memory device 4 and the attribute information, etc., associated therewith) appears one from the respective library devices.  The similar operation is possible with the second unit as well while the first unit of the device operates on the video and audio input mode in this state and, therefore, the parallel operation is possible. The size and cost of the devices are reduced by connecting plural units of the library devices by using the LAN.
