Title: Information processor
Inventor: KARASAKI SADAJI
IPC: G06F13/00
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To effectively demarcate a fault and perform effective maintenance without providing any dedicated service processor by storing respective programs which control the fault demarcation, maintenance, and normal operation of the processor in the same address space dividing with memory banks. SOLUTION: A start program stored in a nonvolatile memory 103 is executed after the power source is turned on and while respective memories and an I/O device 108 are in normal operation, a control program is executed by switching to the memory bank of an electrically erasable and writable nonvolatile memory 104 where the control program is stored. In the case of abnormality, a program which demarcates a fault and performs maintenance is executed by switching to the memory bank where the diagnostic maintenance program is stored. Therefore, the program execution space can effectively be used, so even if the program execution space is small like an information processor which has no service processor, the fault demarcation and maintenance can effectively be performed.

Title: Active matrix type liquid crystal display panel
Inventor: ONOZUKA YUTAKA
IPC: G02F1/136
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To provide an active matrix liquid crystal display panel having good characteristics which can be formed in a small number of processes. SOLUTION: An ITO layer 16 and a metal layer 10 are patterned at one time to form signal wire electrodes and pixel electrodes. Since an oxide layer 11 is etched to expose the metal layer 10 on the signal metal layer 10, the ITO layer 16 is in contact with the metal layer 10. However, since the ITO layer 16 is shielded by an oxide film layer 15 from the light-shielding layer 2, the ITO layer 16 is not in contact with the layer 2. Thus, a leakage current between the pixel electrodes and signal electrodes can be suppressed.

Title: Automatic level control circuit
Inventor: ODA TOSHIAKI
IPC: H03H19/00
Filed: 1987-09-08
Abstract: PURPOSE:To realize an automatic level control circuit with a MOS integrated circuit by converting the variance of an input level to the change of the sampling frequency of a first switched capacitor and moving the frequency characteristic curve of a filter in parallel to compensate the variance of the input level. CONSTITUTION:All of used operational amplifiers consist of MOSFETs. An input level vi, an output vRE of a rectifier 1, an oscillation frequency fs of a voltage controlled oscillator(VCO) 2, and an output v4 of a switched capacitor filter(SCF) 4 in the reference state are vio, vREO, fso, and v40 respectively, and the output vRE of the rectifier 1 is changed to aVREO when the input level vi is changed to avio. As the result, the oscillation frequency fs of the VCO 2 is changed to afso. That is, when the sampling frequency is raised by (a)-number of times in SCFs 4 and 5, the frequency characteristic is moved in parallel in the direction of the frequency base because the cut-off frequency is raised by (a)-number of times also. Thus, the automatic level control circuit is realized with the MOS integrated circuit.
