IPC: B65H18/14
Filed: 1988-10-19
Abstract: PURPOSE:To detect a state of roll paper without fail by repeating the rewinding and winding of the roll paper at a time when a tip of the roll paper is not detected in a paper feed port till the specified time has elapsed. CONSTITUTION:A specified time by a time-counting means 20 is counted in advance since the winding of roll paper 4 loaded in a hopper 1 has started, and a tip of the roll paper 4 is detected with a feed detector 7 in a paper feed port 8 till the specified time has elapsed, and when this detection fails to be done, the rewinding and winding of the roll paper are repeated by a drive mechanism part 50 through a command out of a control part 6A. When a detection signal is outputted out of a residual quantity detector 15 while another detection signal out of the feed detector 7 is outputted, a residual winding quantity of the roll paper 4 is regarded as being completed. Thus, state detection of the roll paper in the hopper becomes secured, and thereby each case that paper feeding is not performed in a state of the roll paper in the hopper being set, and that supply of the roll paper is required for the hopper by no residual quantity is knowable with certainty.

IPC: G03F7/207
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a best focus measuring method for an exposing machine which is not changed by the operator. SOLUTION: A mask pattern has, on one side of a light-intercepting film 10, a transmitting section 14 and a shifter section 12 arranged sequentially from the side of a light-intercepting film 10, and generates a phase difference αin a range of 0 deg.<α<180 deg. between a light transmitted through the shifter section 12 and a light transmitted through the transmitting section 14. This mask pattern is transferred onto a resist film provided on an image forming plane, thus forming a first resist pattern 20a due to a shifter edge 16 and a second resist pattern 20b due to the light-intercepting film 10.  Then, the focus in the case where the distance between a center position 24 of the first resist pattern 20a and a linearly symmetrical center position 26 of the second resist pattern 20b is equal to the distance between the position of the shifter edge 16 and a linearly symmetrical center position 18 of the light-intercepting film 10 on the image forming plane is determined as the best focus.

Title: Time-series pattern recognition device
Inventor: OGAWA HIROAKI
IPC: G10L15/12
Filed: 1994-10-28
Abstract: PURPOSE: To obtain flexibility to variation of an input pattern and to easily add a standard pattern. CONSTITUTION: The speech signal inputted from an input device 1 is analyzed by an analysis part 2 and a feature parameter conversion part 3 extracts a feature parameter. This feature parameter is processed by the GGM conversion of a GGM conversion part 4. This GGM conversion is performed by using mapping having a function fm (X), represented as the linear sum of the products of Lm functions g1m (X) and coefficients c1m , as a function of an (m)th component. A category score arithmetic part 5 converts the output of the GGM conversion part 4 into a score and outputs it to a DP score arithmetic part 6. The DP score arithmetic part 6 compares a pattern stored in a recognition pattern storage part 7 with the output of the category score arithmetic part 5 and calculates the distance between the both. Then the recognition pattern having the shortest distance is outputted.

Title: Production of bottled mineral water
Inventor: NAGANO MANABU
IPC: A23L2/00
Filed: 1998-09-18
Abstract: PROBLEM TO BE SOLVED: To fill sterilized mineral water into a PET bottle without deforming the bottle by rinsing the PET bottle with hot water, then overflow-filling mineral water kept at a specific temperature into the bottle without suddenly changing a filling pressure, and thereafter capping. SOLUTION: When beverage containing mineral water is to be filled, first, a PET bottle 1 is rinsed with hot water. The rinsing is done by injecting the hot water from a bottle mouth into the bottle evenly while falling down the bottle 1. Then mineral water kept at 75 to 77 deg.C is overflow-filled into the bottle 1 without suddenly changing a filling pressure. That is, if the filling pressure is suddenly changed, the bottle 1 tends to swell and deform since it has been softened under a high temperature. Therefore, while a level of the mineral water in a supply tank is being controlled at 1/2 to 1/3 of a full capacity, the mineral water is overflow-filled so that the bottle mouth may not come into contact with a sleeve of a nozzle 3.
