Patent JP-S6116647-A (JP)
Title: Fault recognition system
Inventor: ITOU KIYOHIKO
Filed: 1984-07-02
Abstract: PURPOSE:To prevent an error in the recognition of a fault due to an extending fault by sending an extending fault removal signal out of a center station as to the fault recognition system of an optical communication network. CONSTITUTION:If a fault occurs, the light instantaneous fault of a system 1 is latched in an extending fault factor register (ALMREG1)12 and an extending fault factor is latched in (ALMREG3)14. Then, when said extending fault removal signal (CTL)18 is received by a 0-system terminal device control part (TDS2, 0)7, it is checked whether the bit of an initial head ALM is set or not and when so, the extending fault factor register (ALMREG2)13 is reset to remove the factor. The terminal device control part (TDS3, 0)9 of the system 0 is operated similarly. Namely, an extending fault removal signal (CTL)18 is sent out of the central device by setting the initial head LAM bit to ''0'', and the bit is set when an initial fault occurs, thereby removing the extending fault factor by using the signal.

Abstract: PURPOSE:To enable to contain a condenser of large capacity by covering the back surface of a pellet with an insulating film, and sealing the pellet in a case in this state, thereby increasing thermal strain and electric stability. CONSTITUTION:A silicon nitrided film (Si3N4)102 is formed on a silicon substrate 101, selectively etched, and boron is doped by ion implantation. Then, it is oxidized to form a field oxidized film 103 and a channel stopper 104 under the film. A gate oxidized film 106 and then source 107 and drain 108 are formed on the silicon exposed surface, from which the film 102 is removed, and metal wirings 109 are formed on the respective regions. The oxidized film on the back surface is removed, an oxidized film 110 is formed by vapor growth in the desired thickness, and a semiconductor element in which the back surface of the pellet is covered with the insulating film is obtained. Then, metal is adhered to the entire back surface to form electrodes, and a thick metal 113 is formed thereon, thereby obtaining a semiconductor element in which a condenser is formed on the back surface of the pellet.

Abstract: PURPOSE:To reduce a manufacturing cost, prevent a case from dropping and display recorded contents of an information recording medium by closing a pair of file frames with receiving frames facing each other on internal faces and joining them so that they can be opened/closed with respect to each other with an adhesive tape adhered to an external face on one of their sides. CONSTITUTION:A pair of file frames 2a, 2b are closed with their internal faces of the frames facing each other. Since the file frames 2a, 2b making the pair are of an equal shape, a peripheral wall 7a of the file frame 2a and a peripheral wall 6b of the file frame 2b are butted in this closed state. The file frames 2a, 2b are coupled to each other by an adhesive tape 12 along external faces of the peripheral walls 7a, 6b in this state. Since the adhesive tape 12 is flexible, the pair of files frames 2a, 2b are coupled so that they can be freely opened/ closed. The adhesive tape 12 has a pocket, and recorded contents of a compact disk to be stored are displayed on the pocket.

Title: Semiconductor device
Inventor: KATAGIRI MASARU
IPC: H03F1/42
Filed: 1981-09-01
Abstract: PURPOSE:To obtain a semiconductor device capable of stably protecting input and output against overvoltage such as external surge by forming a P-N junction made of high density impurity region supplied with input and output signals in a high dielectric structure. CONSTITUTION:When an input signal IN is supplied to a metallic film 18, the signal is supplied through a hole 34 to a polysilicon film 33-1, then to an N<+> type layer 14-2, and when an external surge such as overvoltage is supplied to the metallic film, most of the surge current produced at that time is flowed through P-N junctions 35-1, 35-2 to ground side of a power line connected to P<+> type layers 12-1, 12-2. At this time, P type impurity regions 31-1, 31-2 forming the P-N junction are low density, and since the polysilicon film is connected to the metallic film, the film becomes equal potential to the N<+> type layer. Accordingly, the P-N junction and the thin insulating films 32-1, 32-2 are formed in high withstand voltage structure. Consequently, the damage of the junction of the P-N junction produced due to the supply of the concentrated surge current can be prevented.

Further, it is provided with a computer 9d which stores a relation between a deviation between the numbers of revolutions and an ignition timing correction amount by means of a map, and inputs the deviation between the numbers of revolutions to output an ignition timing correction amount. In this constitution, the relation between the deviation between the numbers of revolutions and the ignition timing correction amount, stored in the computer 9d by means of a map, is set in a non-linear manner. Thus, even when the deviation between the numbers of revolutions is low, a high ignition timing correction amount is provided. This constitution enables rapid stabilization of the number of revolutions of an engine available especially during constant speed low load running.
