Patent JP-H03210940-A (JP)
Title: Core
Inventor: GOIE MASATO
IPC: B22C9/10
Filed: 1990-01-16
Abstract: PURPOSE:To eliminate gap between a core print and a core print hole in upper and lower ends of a core and to prevent entering of molten metal by forming the core print at upper end as the separate body from the main body and also this core print as restrictively movable in vertical direction and as shiftable in horizontal direction. CONSTITUTION:The core 3 is fixed in a drag 2 through the core print 5 and the core print hole 7 and successively, the core print 4 is laid on the upper end of core 3 and jointed with a cope 1. The core print 4 and the core print hole 6 are engaged without any interference. That is, as the space is formed between the core print 4 and the core print hole 6, the shift of core print in horizontal direction is possible. On the other hand, as outside dimension of the core print 4 is formed to the same dimention as inside dimension of the core print hole 6, the core print 4 is fitted in the core print hole 6 at the time of completing joint with the cope 1 and the shift in vertical direction is restricted. Therefore, the core 3 is inserted and fixed with the cope 1 and the draft 2, and the entering of molten metal into between the core print 5 and the core print hole 7 and into between the core print 4 and the core print hole 6, is prevented.

Title: Toner recovery device in electrophotographic copier
Inventor: ODA GOROU
IPC: G03G21/10
Filed: 1980-01-25
Abstract: PURPOSE:To make possible the reuse of the recovered toner by providing a number of rudder wheels supporting a rudder chain and disposing a toner sealing material for the prevention of the entry of the toner between the wheels and a shaft. CONSTITUTION:The 1st rudder wheel 20 of the toner recovery device is secured to the shaft 8 of an auger 7, in the front part of a toner discharge port 16c, and the 2nd toner conveying path 25 of which the section assumes a square shape rises diagonally upward from this part and extends in a transverse direction after rising for a predetermined distance. A rudder chain 18 is extended between the 1st and 2nd rudder wheels 20, 17, and since the wire sizes of the links constituting this are small, the toner remained after the transfer easily goes therethrough even if it is held between the rudder wheels 20, 17 and the chain 18, thus no excessive load is applied upon the toner. Therefore, the toner does not lump, and the reuse of the toner is made possible.

Title: Liquid crystal display device
Inventor: SHIN YASUHIRO
IPC: G09G3/18
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To provide the liquid crystal display device which obtain nearly the same contrast for pattern display and matrix display. SOLUTION: To select an electrode X0 as an object of pattern display, a control signal CONT is held at level 'L' for (N-1) clock cycles. Consequently, shift pulses SP outputted from an AND 51 are thinned out by as many as (N-1) and the electrode X0 is driven continuously for N clock cycles. To select electrodes X1 to X4 as objects of matrix display, the control signal CONT is held at level 'H'. Consequently, the electrodes X1 to X7 are selected and driven in order in every clock cycle. The value N is properly set and then the pattern display and matrix display are nearly equalized in contrast.
