IPC: B21B23/00
Filed: 1983-11-25
Abstract: PURPOSE:To improve remarkably the advancing speed of a material to be rolled by applying a tensile stress, within a range of the yielding stress of the material, in reducing the wall thickness of tube end by rolling. CONSTITUTION:A mandrel 13 is inserted into the inner circumference of the end 6A of a pierced and elongated, hollow tube stock 6.

Title: Image input device
Inventor: TSUKAGOSHI EIJI
IPC: G03B27/54
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To obtain optimum luminous quantity by varying an incident angle of an illumination light depending on a kind of an original. SOLUTION: A position of a light source 22 is changed depending on the kind of an original 4. When the original whose surface is smooth is read, the light source 22 is moved to a 1st lighting position A remote from the original so as to decrease an incident angle of the light with respect to the original face. On the other hand, in the case of reading the original whose surface is rugged, the light source 22 is moved to a 2nd lighting position B close to the original so as to increase the incident angle of the light with respect to the original face thereby decreasing the effect by a regularly reflected light component. An original kind detection means 32 detects the kind of the original 4 and provides an output of its output signal to a CPU 31.  The CPU 31 drives a lighting position changeover means 28 based on the received signal to move the light source 22 to a position depending on the kind of the original 4.

Title: Communication control equipment
Inventor: KAMIYAMA TOSHIHIRO
IPC: H04L69/14
Filed: 1985-10-08
Abstract: PURPOSE:To switch from a line connection mechanism generating a fault to an available line connection mechanism without stopping the whole system with economical constitution by forming a line number converting means, a control means, and so on. CONSTITUTION:When a fault is generated in a line connection mechanism having line No.0, the conversion information of the line No.0 is updated from 0 to n by the line number converting means 5. Since the conversion information corresponding to the mechanism 2-0 out of the contents displayed on a display means 7 is changed from '0' to 'n', a communication line 1-n is removed from a line connection mechanism 2-n and a communication line 1-0 is connected to the mechanism 2-n instead of the line 1-n. If a communication request for the line 1-0 is outputted from a CPU 3, the line No.0 inputted in accordance with the communication request is converted into n by the means 5. A control means 6 controls communication between the CPU 3 and the line 1-0 by using the mechanism 2-n having the line No.0. Consequently, switching from the mechanism generating the fault to an available mechanism can be executed without stopping the whole system with the economical constitution.

Title: Storage device for vehicle
Inventor: KOMORI HIROKAZU
IPC: B60R25/04
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To refresh data of an EEPROM at proper intervals in the service life of a vehicle without using a timer. SOLUTION: In the case of cold starting (an engine cabling water temperature <=40 deg.C) and the completion of warming up (an engine cooling water temperature >=80 deg.C), a counter of a backup RAM is set by one increment (step 111 to 113). Therefore, when a count value of the counter of the backup RAM reaches a prescribed value (n), that is, when the number of operation times in which operation is continued up to the completion of warming up from cold starting reaches the prescribed number (n) of times, the counter is cleared to 0 (step 115), and data of the EEPROM is refreshed (step 116). In this case, refreshment of data is performed by directly writing its data on the same address of the EEPROM by reading out storage data of the EEPROM.
