Title: Gas meter with output pulse monitor of watch dog timer
Inventor: NUKUI KAZUMITSU
IPC: G01F3/22
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the impossibility of the shut-off of a shut-off valve from a microcomputer by providing a WDT pulse monitoring circuit for detecting that the output pulse of a WDT circuit is not output for a predetermined period to supply a forcible shut-off signal for closing the valve to the valve. SOLUTION: A circuit 24 for monitoring the WDT pulse to be output from the WDT circuit of a microcomputer is externally attached. If the WDT pulse is abnormal, the circuit 24 outputs a forcible shut-off signal O5 to forcibly close a shut-off valve 22 and supplies a WDT pulse abnormal signal O6 to a controller 20. The controller 20 stores the history of the abnormality in a memory. Since the memory value of the internal RAM is cleared if the microcomputer is recovered by resetting, the reuse of a gas meter itself is inhibited. Thus, even if the valve 22 is opened manually to intend to recover the meter, the valve 22 is again closed by the recover inhibiting function of the microcomputer 20.

Title: Lsi package
Inventor: OE SHUICHI
IPC: H01L23/50
Filed: 1990-10-25
Abstract: PURPOSE:To reduce radiation of unnecessary electric waves emitted from a signal line on a printed board connected to an LSI, to stop the entrace of external noise, and to prevent failure of the LSI, by incorporating a ferrite core through which lead wires pass outside. CONSTITUTION:A package of an LSI with lead wires is designed to incorporate a ferrite core through which lead wires pass. For example, an LSI chip 1 is connected to a lead terminal 4 in the wire bonding portion 2, and a led terminal 4 passes through a ferrite 3.5. An upper ferrite 6 has a hollow square shape, so that a lead terminal 9 can be surrounded by an upper ferrite 8 and a lower ferrite 10. In this way, the LSI is connected by incorporating a noise filter in the LSI package. On the signal line between LSIs, only low frequency remains because high frequency components of parasitic oscillation is eliminated when the noise filter is not inserted. Therefore, circuit operation is stabilized. In addition, trouble due to unnecessary radio waves can be reduced.

Title: Program loading system
Inventor: SAKAMOTO HIROYUKI
IPC: G06F9/445
Filed: 1989-11-08
Abstract: PURPOSE:To shorten starting time by mounting a ROM storing a loader, a RAM to store temporarily a load program, and a non-volatile memory to store semipermanently the loaded program, and storing the revision of the program of terminal equipment on an external storing medium. CONSTITUTION:Since an EEPROM 6 can be rewritten electrically, and in addition, it is the non-volatile memory, the program of the terminal equipment loaded in a definite way and stored never disappears. Before the program of the terminal equipment is loaded from the external storing medium 8, the revision of the program of the terminal equipment is loaded from the external storing medium 8, and since only when the revision is updated, the program of the terminal equipment is loaded, it is unnecessary to load the program of the terminal equipment every time. Thus, since the update of the revision is detected automatically, the operation of a keyboard is not required for loading. Thus, the time from the switching-on of the power of a video data terminal to the start of the operation of the operator can be shortened.

Filed: 1995-11-08
Abstract: PROBLEM TO BE SOLVED: To improve a long period of semiconductor device by growing a compound semiconductor layer while diffusing the interlattice atoms produced by couples of Frenkels generated in the compound semiconductor layer, into the surface. SOLUTION: In an HBT, an n<+> -type GaAs layer 32a, a nondoped GaAs layer 32b, a GaAs base layer 33 being made p-type by adding C, and an AlGaAs emitter layer 34 being made n type are made in order. Usually, in epitaxial growth, the addition of C into the base layer 33 is performed at a low temperature of about 500 deg.C. On the other hand, the growth of the emitter layer 34 is performed at a high temperature of about 650 deg.C, so the occurrence of couples of Frenkels arises most fiercely during growth of the emitter layer, and defects are developed in the emitter layer 34. Therefore, putting the growth temperature of the base layer 33 to 620 deg.C will increase the growth speed of the couples of Frenkels, and accelerate the diffusion into the surface of the interlattice atoms, and the deterioration of the element will be suppressed.
