Title: Automatic document feeder
Inventor: HASHIMOTO KENJI
IPC: G03G15/04
Filed: 1990-06-08
Abstract: PURPOSE:To precisely detect the size of a document by storing the value of a pulse counter every time the document is not detected by a document existence detection part which detects that the document is passed as the length of the document and deciding the size of the document based on the value. CONSTITUTION:A pulse signal generation part 34 which outputs a pulse signal corresponding to a carrying distance when the document is carried, the document existence detection part 15 which is provided on the carrying path of the document and which detects the existence of the document and a storage part 32 which stores the length of the document corresponding to the number of the pulse signals from a time when the document is detected by the detection part 15 are provided. Then, when the number of the pulse signals outputted from the generation part 34 becomes a prescribed number, the size of the document is decided by a size decision part 32 based on the length of the document stored in the storage part 32. Thus, the size of the document is precisely detected even in the case that the document is punched or the like.

Title: Communication control system for cashless restaurant system
Inventor: KOBAYASHI KATSUYA
IPC: G06Q30/06
Filed: 1987-06-19
Abstract: PURPOSE:To improve a processing speed, for example, to omit the time-out time at a communication abnormality time or a re-sending procedure, etc., by putting information that whether the data sent at a previous time are effective (OK), ineffective (NG) or a receiving error (ER) into a polling command. CONSTITUTION:To the host computer of a master station, the numerous slave stations of a magnetic card reader is connected by a communicating line. The master station calls the slave station with an address and transmits a polling command (POL). The slave station returns the card data of a customer and questions propriety. The customer knows the propriety of an eating by a lamp display according to the propriety. When the slave station misses the response of the master station, the master station ignores it once, successively moves to the next slave station, after a turning around of all the slave stations, is back to the starting slave station and together with POL transmission, transmits effective (OK) information to the slave station. Thus, a procedure that the slave station waits for a time-out time and data are re-sent is omitted and a processing speed is improved.

IPC: G03F7/26
Filed: 1989-06-14
Abstract: PURPOSE:To obtain a high density and accurate resist pattern having satisfactory adhesive properties with the surface of a substrate and satisfactory followability to an uneven part of the surface by employing a composite photosensitive layer made of a photosensitive layer formed by electrodepositing and a photosensitive layer laminated with a photosensitive film thereon. CONSTITUTION:A positive or negative type photosensitive layer (I) is formed by dipping a conductive substrate in an electrodepositing coating bath, and conducting it to electrodeposit it, and further a filmlike photosensitive layer (II) containing positive type photosensitive resin composition if the layer (I) ls positive or negative type photosensitive resin composition if the layer (I) is negative is laminated thereon. Thus, a uniform film having satisfactory followability of the surface of the substrate to the uneven part and satisfactory adhesive properties without pinhole can be formed, and the reliability of the resist can be largely improved that much. In addition, a land having large opening can be ramarkably reduced, thereby obtaining the substrate having high density and high accuracy resist pattern.

Filed: 1982-09-01
Abstract: PURPOSE:To detect a runaway of a CPU system in a short time on the basis of the output of a counter which counts the output of a pulse generator, by presetting the counter periodically by a microcomputer system. CONSTITUTION:Pulses P1 from the pulse generator 2 are inputted to the counter 3 and an AND gate 4, and the counter 3 counts it on quad basis, is reset by a pulse signal P2 from the CPU system 1, and outputs a signal S1 synchronously with the signal P1 when its count value changes from 3 to 0. A CPU1 outputs a set signal S2 when a program is started to raise the level of an FF5, which outputs an S3 with a level 1 to open the AND gate 4 synchronously with the signal P1; and a relay driving circuit 9 is driven through a one-shot multivibrator OS6 to close a contact 11. The CPU1 outputs the pulse P2 while the program is executed normally, but the P2 is ceased once a runaway occurs and the counter is driven to output the signal S1 in the 3-to-0 transition; and the FF5 is reset to invert the signal S3 to 0 and the contact 11 of the relay driving circuit 9 is opened to detect the runaway in a short time.

Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To easily separate and replace a W/P seal slip by preparing a write decision part having a seal sticking surface including a recess part. SOLUTION: A write decision part 32 having a seal sticking surface of a circular recess shape, for example, is formed on the surface of a base card 22. The part 32 is located between a contact terminal 28 and a label 30. A separating recess part 32a of a slit shape is formed on the seal sticking surface. The part 32a is tilted so that the seal sticking surface of the part 32 reduces its depth from the outer circumference toward the center of the seal sticking surface in the depth with which a W/P seal slip 3 having a write inhibiting function can surely secure a sticking enable area. Thus, it's possible to easily separate the slip 3 by putting the tip of a separating tool such as a pincette, etc., into the back of the slip 3 from the edge of the part 32a and then moving the tool tip along the bottom surface of the part 32a.
