Title: Lathe-turning tool
Inventor: SHIMANO TAKAMASA
IPC: B23B27/22
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To prevent a cutting blade and a worked surface, etc., from being flawed by applying guidance and control to chips. SOLUTION: A front guide plate 20 is installed on the front cutting blade 17 of a throw-away tip 15 installed on the point angle part of a cutting tool head part 12, and; a transverse guide plate 24 is installed on a transverse cutting blade 18. Each guide plate retreats on the top surface 16 of the tip side rather than the cutting blade to provide a space between the cutting blade and the top surface of the tip. Chips are guided to the top surface 16 of the tip side partitioned by both the guide plates 20, 24 or are collided with both the guide plates 20, 24. Thus, disconnection, and direct collision with the cutting blade and a worked surface are prevented.

Title: Step motor drive circuit
Inventor: HIRATA RYOICHI
IPC: H02P8/30
Filed: 1989-03-17
Abstract: PURPOSE:To produce high rotary torque stably and efficiently by turning an exciting coil OFF through a switching means at a time point when a current comparing means detects that the current flowing through the exciting coil has exceeding over a preset current level. CONSTITUTION:Control signals 27, 28 are fed to D/A converting circuits 7, 11 which then output two types of voltage according to whether these signals are High or Low. If a phase switching signal 20 goes to High level at time (t1), output voltage 26 of an AND gate 12 goes to V2 level and a MOSFET 3 is turned ON thus starting power conduction to an exciting coil 1. Consequently, the negative input voltage 21 of a current setting comparator 6 increases and when it exceeds over a positive input voltage 22 at time (t2), output voltage 23 of the comparator 6 goes to GND level. Consequently, output voltage of a non-conduction time setting comparator 10 goes to GND level while output voltage 26 of the AND gate 12 also goes to GND level thus turning the MOSFET 3 OFF and bringing the exciting coil 1 into non-conducting state.

Abstract: PURPOSE:To eliminate the time and labor required for making the repeat of copying operations and even allocation by making calculation of the maximum number of displayable pieces and even allocation possible when only a document size and displaying area are instructed. CONSTITUTION:A document designating means 3 designates a document to be copied from a document preparing picture and a displaying area designating means 4 selectively designates a displaying area to be used for display. The document, document size, and displaying area designated in the course of the above-mentioned processes are stored in a document storing means 5. The storing means 5 outputs the document designated for copying, document size, and displaying area and discriminates whether or not the designated document can be copied in the designated displaying area. When the document is copyable, a calculating means 6 finds the maximum numbers of displayable pieces in both longitudinal and lateral directions of the designated area, and when the document can be allocated to the area, calculates and stores in a displaying position storing means 10 the displaying positions of each leading part of the document to be copied. When the document cannot be allocated, an internal process is performed so that the excessive lines can be inserted evenly into the designated area.

Title: Method of erasing after-image of accumulation type fluorescent material sheet
Inventor: SAITO YUJI
IPC: G03B42/02
Filed: 1988-03-18
Abstract: PURPOSE:To reduce the size of an erasing mechanism which has a light source for erasing and is shorter in size than an accumulation type fluorescent material sheet by intermittently introducing the accumulation type fluorescent material sheet into the above-mentioned erasing mechanism and projecting erasing light successively to the accumulation type fluorescent material sheet in the erasing mechanism, thereby erasing the radiation images remaining thereon. CONSTITUTION:The accumulation type fluorescent material sheet S is stopped when the arrival of the accumulation type fluorescent material sheet S at the erasing mechanism 47 is detected by a 1st optical sensor 48 and further after the sheet is carried for the prescribed time at a relatively high speed. The light source 64 which constitutes the erasing mechanism 47 is then lighted to erase the picture information remaining in this position. The accumulation type fluorescent material sheet S is carried again at a relatively high speed and is stopped where the other part of the accumulation type fluorescent material sheet S is opposed to the light source 64 for erasing. The accumulation type fluorescent material sheet S is stopped upon lapse of the prescribed time after the arrival of said sheet at a 2nd optical sensor 68 is detected. The image remaining on the accumulation type fluorescent material sheet S is then erased. The size of the erasing mechanism is thereby reduced.
