Title: Automatic ticket examination machine
Inventor: ARAYAMA KIYOSHI
IPC: G07B15/00
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To improve entrance processing performance by providing an entrance permission control means for permitting entrance with the insertion of a train ticket satisfying an entrance condition among the plural tickets where boarding sections continue as a condition. SOLUTION: It is assumed that a user who is to enter from a station A and to leave from a station C possesses the two commuter tickets (1) and (2). When the commuter ticket (1) satisfies the entrance condition, entrance data is recorded and a door is opened. When the commuter tickets (1) and (2) are collectively inserted, only the commuter ticket (1) is processed and the commuter ticket (2) is not processed. Since the user can enter only by inserting the commuter ticket (1) satisfying the entrance condition, processing performance can be improved. In the station C, the user can leave when the commuter ticket (2) satisfies the leaving condition, entrance data exists in the commuter ticket (1) on an entrance-side and the boarding sections of both commuter tickets (1) and (2) continue are set to be the conditions, and therefore the illegal boarding can be prevented.

Title: Solid-state image pickup element
Inventor: IDOUJI TAKASHI
IPC: H01L29/762
Filed: 1996-04-17
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state image pickup element which has dissolved the shortage of the dynamic range of signal output accompanying the lowering of amplitude of a reset gate. SOLUTION: A CCD solid-stage image pickup element is composed of an FD (1) 7 at the first stage of floating diffusion constituted in n stages, a reset gate RG (1) 8 where RGϕ1 pulse is applied, a floating diffusion FD (n) 10 at the nth staged and a reset gate RG (n) 11 where RGϕn is applied. Then, even in the case where the amplitude of the reset gate to reset floating diffusion is lowered, the signal charge having overflown at the nth stage can be caught at the n+1th stage, so the shortage of the dynamic range of the signal output in the solid-state image pickup element can be dissolved.

Title: Separation of liquid by semipermeable composite membrane consisting of furufryl alcohol polymer
Inventor: UEMURA TADAHIRO
IPC: B01D65/06
Filed: 1979-07-27
Abstract: PURPOSE: To prevent the lowering of the separating capacity of the composite semipermeable membrane by adding a sulfite, etc., to the liqiud to be treated and performing its separating treatment within 5 minutes in the separation of inclusions from the liquid by a reverse osmosis method using the specific semipermeable composite membrane.  
     CONSTITUTION: By using the composite membrane as a barrier layer, consisting of a thin membrane formed by coating a solution containing furfuryl alcohol, a multivalent organic acid reactive to furfuryl alcohol, a polyhydric alcohol, and an acid catalyst, e.g., sulfuric acid, on a porous supporting membrane consisting of a homopolymer or a blended polymer, followed by cross-linking polymerization, industrial water, sea water, etc., is treated to separate valuables present from the water. In this case, 5W100ppm of a sulfite, a bisulfite, or sulfurous acid gas is added to the liquid to be treated and the liquid is treated by the reverse osmosis method within 5min. Because active oxygen derived from dissolved oxygen in the liquid during the treatment is soon inactivated by a sulfite, etc., the oxidation of the composite membrane by the active oxygen can be prevented and thereby its own separating capability can be protected from deterioration. Thus, the durability of the composite membrane can be raised.

Abstract: PURPOSE:To generate a character pattern of high quality by correcting the position of an inflection point where the quality of similar conversion is considered to decrease among inflection points extracted from a contour and performing the similar conversion by using line width control information generated according to the corrected inflection point. CONSTITUTION:Information on the inflection points extracted from the contour of a character pattern is supplied to a correcting means 11 and when the specific inflection point where the quality of the character pattern after the conversion is considered to decrease is detected, a correction part 111 corrects the position to a position where the character pattern quality is improved. Then an adding means 12 adds the line width control information to an inflection point which is significant for line width control and a line width control value generating means 13 generates a line width control value according to the corrected inflection point and line width control information. The line width control information and the line width control value are referred to by a line width control means 14 and used to control the line width, thereby enlarging or reducing the character pattern. Consequently, the enlarged and reduced character pattern of high quality are obtained from one original character pattern.
