Title: Method and device for evaluating quality of printing
Inventor: HANSU OTSUTO
IPC: B41F31/04
Filed: 1984-11-05
Abstract: Printed products and their respective corresponding printing plates are divided into a plurality of image elements. For each image element the surface coverage is determined by photoelectric measurements; a reference reflectance value is then calculated from these measurements, taking into consideration such parameters as the printing characteristic. These reference reflectance values are compared with the actual reflectance values measured on the printed products and the results of the comparison are evaluated to form a quality measure and to calculate control values for the ink feed devices of the printing machine. In this manner, the use of special color measuring strips may be eliminated.

Abstract: PURPOSE:To make thermal contacting property between a substrate and a semiconductor substrate excellent and to heat-treat the semiconductor substrate excellently in in-surface uniformity and reproducibility by bringing a substrate kept at a specific temperature into contact with a semiconductor substrate through a substance which is excellent in adhesion and conductivity. CONSTITUTION:A supporter 2 one part of the surface of which is covered with molten metal 3 being a substance which is excellent in adhesion and conductivity is heated to and kept at a specific temperature by a heating source 1. At this time, the molten metal 3 is rising to the temperature same as the supporter 2, and when a semiconductor 4 to do heat treatment is brought into contact with there, even if a pattern having a step is formed at the surface of the semiconductor substrate 4, since the molten metal 3 exists between the supporter 2 and the semiconductor substrate 4, substantially the same effect that the supporter 2 and the semiconductor 4 are in close contact with each other can be obtained. For this reason, ununiformity of temperature distribution inside the semiconductor substrate surface by partial contact between the supporter 2 and the semiconductor substrate 4 does not occur, and heat treatment effect excellent in uniformity and reproducibility can be obtained.

IPC: G11B19/06
Filed: 1987-09-18
Abstract: PURPOSE:To measure jitter while reading data by finding the value of the jitter as the position of a latch register by which a read pulse is latched by transferring the read pulse stored in each stage of a shift register to a corresponding latch register.

IPC: H04M7/00
Filed: 1991-09-12
Abstract: PURPOSE:To house various terminas without plural communication channels having the transmission capacity different from that of an existing communication channel. CONSTITUTION:When an incoming request to a second terminal 8 from a first terminal 2 is transferred to a first exchange 1, a first exchange 1 decides whether a terminal number of a second terminal 8 can be recognized or not. As result, in the case a first exchange 1 can recognize the terminal number of a second terminal 8, a first exchange 1 executes an incoming to a second terminal 8 through a second exchange 7, therefore, from the terminal number of a second terminal 8, terminal detailed information of a second terminal 8 is extracted from an internal memory in a first exchange 1, and also, a terminal classification of a second terminal 8 set in the extracted terminal detailed information is extracted. Subsequently, by the terminal number and the terminal classification of a second terminal 8, communication channel between a second exchange 7 and a first exchange 1, being in a first exchange is extracted, and whether the obtained communication channel information is information related to a communication channel group 3 or not is decided.

Abstract: PURPOSE:To restrain a profitable state for a player without spoiling the player's interest in pachinko game by a method wherein an advantageous condition for a player is halted by a signal from an outside detector besides a time limitation. CONSTITUTION:A detected signal of a particular condition is input to a set contact S of a flip flop 31, causing an output to be produced at an output contact Q. An and circuit 32 receives this output and an output from a frequency generator 33, and brings a converter 9 into operation through a driver 34, however, this operation state can be optionally set by the frequency generator 33.

The outside detector 29 is located facing the bottom of a prize ball introducing trough 35 that leads to an outlet of an upper tank 30. The outside detector 29 is turned off when it is pressed by prize balls and turned on when the prize balls become absent, that is released condition to the reset contact R.

IPC: H03H17/00
Filed: 1988-09-16
Abstract: PURPOSE:To perform a fast operation and to realize versatility easily to change tap length by providing N product sum circuits and a coefficient supply circuit to supply a tap coefficient string to each of the N product sum circuits, respectively. CONSTITUTION:The coefficient supply circuit supplies the tap coefficient string C to the N product sum circuits (311-31N), respectively, and each of the product sum circuits (311-31N) obtains a sum of product value SIGMA by accumulating the product of each coefficient c1 and an input signal xn in one cycle of coefficients (c1-cN). The sum of product value SIGMA of each of the product sum circuits (311-31N) goes to SIGMA=c1xn+c2xn-1+...+cNxn-N at a time when the coefficients (c1-cN) for the product sum circuits (311-31N) perform one circulation. Since it is the output signal of a digital filter, a filter output signal series Y can be generated by outputting the sum of product value sequentially from the product sum circuits (311-31N). In such a way, the fast operation can be performed, and also, the versatility in easily changing the tap length can be obtained.
