Patent JP-H11270450-A (JP)
Title: Control device of internal combustion engine
Inventor: KOKUBO NAOKI
IPC: F02D45/00
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To optimize the knocking control when an ion current sensing circuit goes in failure. SOLUTION: When an ion current sensing circuit goes in failure or a wire severance occurs in the secondary circuit of an ignition coil, a judgment of misfiring can be passed from a drop of the output of the sensing circuit, and at such a time, judgement of the knocking is prohibited, and the ignition timing is delayed to the max. angle to suppress the knocking (Steps 101, 105, 106). Thereby misjudgement as non-knocking can be prevented in advance when the ion current sensing circuit goes in failure or wire severance has occurred in the secondary circuit of the ignition coil, so that erroneous advance of the ignition timing (knocking occurrence) due to misjudgement of knocking can be prevented.  Further, because the ignition timing is delayed to the max. angle when knocking judgement is prohibited, eventually generated knocking can be suppressed certainly, and it is possible to preclude damages of a plug electrode or piston by the knocking.

Title: Production of magnetic head
Inventor: MURAOKA SHUNSAKU
IPC: G11B5/127
Filed: 1985-04-06
Abstract: PURPOSE:To prevent the generation of air bubbles by forming a proper level difference having the prescribed width or larger between a gap surface and a molded glass surface. CONSTITUTION:A proper level difference d' is formed between a gap surface and a molded glass surface by a chemical etching process, a mechanical processing, etc. The glass of a low melting point is melted by heating. In this case, the glass upper end does not reach the gap surface of a core half 1 despite the waving of the glass surface since a sufficient space is secured between the molded glass surface 4'' and the gap surface 6. When the heating temperature is increased more, the glass flows to the side face 5' of a breathing groove 5. Thus the glass enclose no air and therefore a glass stuck layer contains no air bubbles. This improves the head yield.

Title: Thermal roller type fixing device
Inventor: ITOU TAKASHI
IPC: G03G15/20
Filed: 1981-05-18
Abstract: PURPOSE:To reduce the thermal effect on a bearing of a roller and to maintain the durabillity, by increasing the surface temperature of a heating roller only at fixing and keeping the surface temperature lower in other periods. CONSTITUTION:In a fixing device when a heating roller 1 and a pressing roller 2 rotate in synchronizing with a recording operation, a gear 9 geared with a drive gear 11 of the roller 1 is turned. As a result, a temperature sensor senses that the surface temperature of the roller 1 is low and a current fed from a control circuit 4 to a heater 1a is increased. Thus, the heat of the heater 1a is increased and the surface temperature of the heating roller is increased. Thus, the surface temperature of the roller 1 reaches a temperature satisfying the fixing only at the fixing operation and the temperature is kept lower for other periods, allowing to reduce the thermal effect on the bearing of the roller.

Abstract: PURPOSE: To provide a switching device for a LAN which is reduced in packet loss. CONSTITUTION: When a packet is received by a port reception part 1, a receiving buffer storage part 2 informs an address filter part 6 of the storage address of the packet acquired from a receiving buffer 3 and the port number of the reception of the packet, and stores this packet in the said storage address of a data buffer 32. The address filter part 6 knows a port from which transmission is performed, informs a transmitting buffer storage part 4 of the storage address of this packet and information on the said port for the transmission, and transfers the packet to the port transmission part 5 of the port, thereby sending it to Ethernet. The transmitting buffer storage part 4 receives and sends the storage address back to the receiving buffer 3.  A receiving buffer capacity decision part 7 decides the rest capacity of the receiving buffer 7 by monitoring the acquiring and resending operation of the storage address in the receiving buffer 3 and sends a jam signal out of the port transmission part 5 when the rest capacity becomes less than a specific value.
