Title: Electronic exchange
Inventor: YASUDA SUSUMU
IPC: H04Q3/545
Filed: 1991-10-01
Abstract: PURPOSE:To prevent disturbance and confusion caused by being connected suddenly to a calling side by considering incoming side off-hook in a delay time corresponding to calling to be a calling operation, and executing preferentially a calling processing. CONSTITUTION:When an electronic exchange 1 detects the calling of a telephone set 2a of a containing extension, a dial tone is sent out thereto. Thus, a calling party dials the telephone number of a called party side. At this time point, a central control unit 6 sets a ring-back tone sending-out delay time T to a telephone set 2a, based on the set value of a calling party level set in advance to a storage device 7. In such a state, in the case the off-hook of the telephone set of the called party side is detected before the delay time T becomes time- out, the controller 6 considers it to be the calling of the called party side, a dial tone is sent from a signal device 5, and subsequently, a busy tone is sent out.

Title: Nonvolatile semiconductor memory device
Inventor: HARA HIDEKI
IPC: H01L27/115
Filed: 1992-08-28
Abstract: PURPOSE:To provide an element structure which facilitates a very fine structure, level the surface and improve the reliability of the contact by lowering the aspect ratio of the contact hole. CONSTITUTION:A substrate insulating film 102 is formed on a p-type silicon substrate 101. Control gates 103, gate insulating films 104, floating gates 105 and tunnel gate insulating films 106 are built up on the insulating film 102. The spaces between respective laminated units composed of the layers 103-106 are filled with a insulating film 107. A semiconductor layer 108 of which channels, sources and drains are composed and whose some parts are converted into n-type impurity layers 108a is formed on the insulating film 107. An interlayer insulating film 109 and a metal wiring layer 111 are formed on the semiconductor layer 108. With this constitution, as element isolation can be achieved without forming field insulating films, a dimension along a word line direction can be reduced and it is not necessary to take a margin between the gate and the contact into consideration, so that a dimension along a digit line direction can be reduced.

Title: Output circuit for semiconductor storage device
Inventor: FUKIAGE TAKAHIKO
IPC: H03K19/0175
Filed: 1992-08-26
Abstract: PURPOSE:To obtain a level of a power supply voltage itself as an output level and to reduce an output noise by providing plural bootstrap capacitors and selecting a capacitor with a laser blow. CONSTITUTION:Capacitors 4a, 4b for bootstrap are connected to a gate of an N-channel MOS transistor (TR) 1 through laser blow use wires 4c, 4d and have almost the same capacitance. Furthermore, the other terminal of the capacitors 4a, 4b is connected to an input node for a control signal phi1 via a delay circuit 5. In order to optimize the bootstrap capacitance, the capacitance of the two bootstrap capacitors 4a, 4b depends on an on-resistance of the NMOS TR 1 and an impedance of an output load. Thus, overshoot due to the mismatching of the output impedance is suppressed by cutting off either one of the layer blow use wires 4c, 4d to select either one of the capacitors 4a, 4b.

Title: Electrophotographic photoreceptor
Inventor: HIRAMOTO HIROYUKI
IPC: G03G5/14
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To suppress the internal temp. rise of a photosensitive drum and to prevent lowering of the image quality such as unevenness in image due to deterioration of characteristics of a photoreceptor and the head of a printer during long-time continuous use in an electrophotographic photoreceptor used in an electrophotographic device adopting a rear exposure system. SOLUTION: Since the photosensitive drum has a transparent heat conductive layer 5 having satisfactory heat conductivity on the rear side of the cylindrical transparent substrate 2, heat generated from a light source 15 for exposure and a light source 19 for de-electrification arranged in the photosensitive drum is diffused to the entire inside of the drum through the heat conductive layer 5 and it is radiated from both open ends of the drum. The temp. rise of a photosensitive layer 4 due to the heat is prevented and the deterioration of characteristics of the photoreceptor such as reduction in the quantity of electric charges is prevented.

Title: Injection molding machine
Inventor: KAWADA AKIRA
IPC: B29C45/26
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To improve reliability on restriction of movement of a mold at the time when a door is opened by providing a link mechanism which separates a stopper from a stop bar against an energizing force by being pressed by the door when the door is under closed condition and is released from pressing caused by the door when the door is under opened condition. SOLUTION: When a door 14 is under closed condition, an actuating arm 28 of a link mechanism 22 is pressed by the door 14 and a stopper 21 is separated from a stop bar 17 against an urging force of a spring 25. Therefore, the stop bar 17, namely, a movable mold 13 does not receive any restriction of the stopper 21 and the movable mold 13 can freely move to a fixed mold and injection molding can be smoothly performed. In addition, when the door 14 is under opened condition caused by maintenance, as the actuation arm 28 of the link mechanism 22 is released from pressing caused by the door 14 and becomes free condition, the stopper 21 is hooked in a channel 18 of the stop bar 17 by the spring 25 and the movement of the movable mold 13 is restricted in the direction of the fixed mold.  As this movement of restriction is mechanically performed, there exists no error motion and reliability can be obtd.

Title: Tip part of side-looking endoscope
Inventor: MIYANAGA HIROBUMI
IPC: A61B1/06
Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To construct an endoscope without increase in an outer diameter of a tip part even in the case of an side-looking endoscope provided with plural light-emitting diodes on the outer periphery of an object optical system. SOLUTION: A substrate 21 provided with plural light-emitting diodes 19 assembled in one piece is in a plane containing the endoscope center axis 25. Similarly, a part of an object 1st surface lens is also in the plane containing the endoscope center axis 25. For a same outer diameter, the largest area is available in the plane containing the endoscope center axis 25, therefore, it is possible to reduce the outer diameter of the tip part 3 of the endoscope as small as possible by arranging the light-emitting diode 19 part group on this plane.

Title: Image forming device
Inventor: INOUE AKIRA
IPC: G03G15/08
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of positive ghost by constituting a contact member of a material by which toner is electrified to the polarity opposite to a normal polarity. SOLUTION: The acrylic fiber of a fixed brush 6 used as the contact member imparts a positive charge to the toner having a polyester surface layer for instance by triboelectrification. In other words, the fixed brush 6 used as the contact member is made of the material by which the toner is electrified to the polarity (positive) opposite to the normal polarity (in this case, a negative) by a troboelectrification series. Further, for instance, a DC bias voltage of +200 V having the polarity (positive) opposite to the normal polarity (negative) of the toner is applied to the fixed brush 6 as the contact member from a bias applying power source S4. Thus, the charge quantity of the toner remaining after a transfer is uniformed and the temporary recovery rate of the toner in an electrifying part 2a is increased to reduce the occurrence of the positive ghost.

Filed: 1985-11-15
Abstract: PURPOSE:To prevent a peeling on the interface on an adhesive surface between a resin and a tab for a lead frame, and to obviate the generation of a resin crack by executing dimple working to a peripheral section while executing proper dimple working into an internal space for a semiconductor device. CONSTITUTION:The inside of an area 7 in proper size containing the center of a tab 2 forms a space, and a large number of dimples 9 are shaped to the peripheral section 8 of the area 7. The transverse center line 10, longitudinal center line 11 and diagonals 12, 13 of the tab 2 are assumed. An intersection 14 where these lines cross shapes the center of the tab. In the area 7, the dimple 9 is formed at the intersection 14 while a proper number of the dimples 9 are shaped onto the center lines 10, 11 and/or the diagonals 12, 13. Accordingly, the concentration of stress only to each corner section or the concentration of stress only toward the center is prevented, thus balancing stress.
