Patent JP-S6249719-A (JP)
Title: Phase comparator
Inventor: MAEDA TETSUO
IPC: H03L7/093
Filed: 1985-08-29
Abstract: PURPOSE:To improve the symmetrical property of the circuit configuration of a phase comparator and constitute the circuit of the same kind of transistors and, at the same time, to suppress an offset smaller even at a high operating frequency, by providing two current sources of the same current value, two sets of differential switches which switch the currents to each other by means of the two sets of outputs of the phase comparator, two load resistances, and a time constant circuit. CONSTITUTION:A phase comparator 101 inputs a reference signal Vr and input signal Vi and outputs differential outputs A, the inverse of A having a fixed time width and differential outputs B, the inverse of B whose time width is the phase difference between the signals Vr and Vi. Differential switches 121 and 122 use current sources 104 and 110 of the same current value and the above-mentioned output as a differential base input and switch the currents of the above-mentioned current sources 104 and 110. Since load resistances 105 and 106 and a time constant circuit 107 convert the phase difference between the signals Vr and Vi into the differential voltage across the output terminals of differential switches 121 and 122 after smoothing, a symmetrical circuit configuration can be realized and, at the same time, the circuit can be constituted of the same kind of transistors. Moreover, since a differential form is adopted, the phase difference-voltage converting offset can be suppressed smaller even if the operating frequency is high.

Abstract: PURPOSE:To manufacture the titled light-weight device easily at low cost by making the distance of extension of the side surface section of an ultraviolet-ray permeable window material surrounded with a synthetic resin on a chip larger than a vertical extension distance to the upper surface section of the window material. CONSTITUTION:In an ultraviolet-ray erasable type programmable read-only-memory (EPROM) device 20, an EPROM chip 22 loaded on an element loading section 21a for a metallic lead frame 21 and an ultraviolet-ray permeable window material 25 fast stuck to an ultraviolet-ray irradiation surface through an ultraviolet-ray permeable resin 24.

Title: Method for processing time synchronization
Inventor: TSURUTA TAKESHI
IPC: G06F1/14
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for processing time synchronization by which the occurrence of errors at the level of milliseconds in a slave device can be eliminated even when time synchronization is made by using time data of the level of seconds. SOLUTION: At the time of executing time synchronization processing, an FEP(front-end processor) reads the time of its built-in clock (S1) and, when the milliseconds of the built-in clock deviates from a tolerance, enters a waiting process until the next correct second comes (S2 and S3). When the correct second comes when the tolerance is met at the next time reading time, the FEP makes time correction by incrementing the seconds of the time by one second (S4 and S5), sets time data (S6), and transmits a time correcting requests to a slave device (S7).

IPC: B67D7/32
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent an oil mixing and to suppress an increase in the wt. of an unloading hose to enhance the managing workability thereof by allowing a hatch to communicate with an oil tank only when the kind of the oil of the selected one among hatches coincides with that of the oil of the oil tank connected by the unloading hose. SOLUTION: When the kind of unloading oil is designated, a control unit 17 permits the opening of the bottom valves 14a-14g of hatches 12a-12g when the kind of the designated oil coincides with the oil kind data held by the oil kind data holding parts 35A, 35B wherein connection discrimination parts 108A, 108B are in an engaged state and allows the oil to flow to oil tanks 27A, 27B through unloading hoses 24A, 24B to permit unloading. When the kind of the designated oil does not coincide with the oil kind data of the oil kind data holding parts 35A, 35B wherein the connection discrimination parts 108A, 108B are in the engaged state, the bottom valves 14a-14g of the hatches 12a-12g are closed to prevent the hatches 12a-12g from communicating with the hoses 24A, 24B.

Title: Loading system for microprogram
Inventor: OZAWA HIDEKIYO
IPC: G06F9/24
Filed: 1986-08-14
Abstract: PURPOSE:To perform the collation and check of contents of control storage parts of all processors just with a single reading operation regardless of the number of processors, by providing a comparator which compares the data on the control storage part and the data on a bus, a driver circuit, etc. CONSTITUTION:A comparator 108 compares the data DATA1 read out of a control storage part CS102 with the DATA2 on a data bus 33 in correspondence of bits. If no coincidence is obtained between both data, a driver DV116 is driven by a signal CTL received from a control circuit 101 for output of an error signal Error. In this case, the comparator 108 of each CPU10 produces a coincidence output as long as the program has no error in the CS102 of each CPU10 in a multi-processor system. Thus the signal Error outputted from each CPU is set at a normal level (0). However the signal Error is not equal to 0 if the program of the CS102 of either one of those CPU10 has an error. Thus an error is decided. In such a way, it is possible to give the collation and check to the CS contents of all processors in a short period just with a single reading operation.

Filed: 1981-11-27
Abstract: PURPOSE:To decrease the diffusion of impurities from an N type layer into an epitaxial layer thereby to increase VCBO and the switching speed, by a method wherein an isolating oxide film is formed all over the silicon surface before epitaxial growth and selectively etched, and then a selective epitaxial growth is effected. CONSTITUTION:An oxide film 6 to be an isolating region is formed on a P type silicon substrate 1 of about 10-20OMEGA<->cm. Next, the oxide film in an active region is removed by photoetching method. Subsequently, through the opening an N type layer 2 to be a low-resistance collector region is formed by ion implantation or diffusion using the remaining oxide film 6 as a mask. Then, an N type epitaxial layer 3 to be a low-resistance collector region is formed. By selecting proper growth conditions, a single crystal silicon epitaxial layer 3 is selectively formed only on the opened N type layer, so that it is possible to obtain such a configuration that the epitaxial layer 3 is buried between the isolating oxide films previously formed.

Title: Liquid crystal display device
Inventor: MISHIMA YASUYUKI
IPC: G02F1/1368
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device with a good visual angle characteristic and uniform display by connecting both terminal parts of common electrode signal lines to common electrode wirings and also reducing resistance value of the common electrode wirings to smaller than that of the common electrode signal lines. SOLUTION: A common electrode signal line 5 connected with a common electrode in a picture element 12 is arranged in parallel with a gate signal line 7, and is further connected to a common voltage generation driving circuit 3 at the both terminal parts of the common electrode signal line 5 via a common electrode wiring 4. At this time, since the common electrode 4 is formed in a non-display area of a matrix board 8 and this makes it possible to widen a wiring width of the common electrode wiring 4, the resistance value of the common electrode wiring 4 can be reduced to smaller than that of the common electrode signal line 5. This reduces driving distortion of the driving voltage supplied to the common electrode from a common voltage driving circuit in the common voltage generation driving circuit 3.  Thus, an electric field intensity between the picture element electrode in each picture element 12 and the common electrode becomes almost uniform and non uniformity in brightness can be reduced.
