Title: Dielectric resonance type band stopping filter
Inventor: MIZUMURA MOTOO
IPC: H01P7/10
Filed: 1985-03-25
Abstract: PURPOSE:To use a metallic chassis and metallic cover which are relatively small in dimension and the same in a certain wavelength zone, by making a conductor pattern formed on a dielectric substrate to make a detour between dielectric resonators. CONSTITUTION:It can be said from a filter theory that, when the electric length, namely, conductor pattern (l) between dielectric resonators is l=l1+l2+l3+l4+l5=(2n-1)X(lambdag/4), the characteristic of a filter becomes the optimum. Therefore, the length L1 can be made smaller as compared with conventional ones at the same frequency and, as a result, the length L of a metallic chassis can be made smaller as compared with conventional ones. Moreover, if the l2 and l4 are appropriately selected when a frequency is fixed, the length L1 can be selected with a considerable degree of freedom. In addition, when this constitution is used, the length L1 can be made constant by selecting suitable values for the detouring widths l2a-l2c of the detouring path of a conductor pattern in a range of l2b>l2a>l2c, so that the electric length between dielectric resonators can become (2n-1)X(lambdag/4) against each of frequencies f2, f1, and f3. Accordingly, the distance L between dielectric resonators also becomes constant and the outer shape of the metallic chassis becomes a fixedly designed one.

Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of electrode terminal part, to suppress the occurrence of electrical defect, to improve the adhesion property between a TFT substrate and a CF substrate, to improve the yield of production, and to decrease the number of production stages by forming the electrode terminal at the electrode terminal as a single layer. SOLUTION: An auxiliary electrode 26 consisting of CR is formed on the CF substrate 24 side. A gate electrode 22 consisting of AL and gate terminal 23 consisting of ITO are connected by a connector 28 consisting of Ag paste with the auxiliary electrode 26 as a joiner. The electrode terminal part of the TFT substrate 21 side is composed of the signal layer of the gate terminal 23 along in this constitution and therefore, the possibility that the electric defect arises is low. The adhesion property of the case the TFT substrate 21 and the CF substrate 24 are such to each other by using a sealing material 29 is good. Both of the gate electrode 22 and the gate terminal 23 are the single layers but the conductive connection is executed without direct contact with each other and, therefore, the problem of insufficient adhesion property does not occur.

IPC: G01R27/14
Filed: 1983-04-07
Abstract: PURPOSE:To obtain results of the measurement at a high accuracy for a short time by measuring an electric constant of a circuit to be measured from a value in a specified phase of a reference voltage or current to be applied to the circuit being measured. CONSTITUTION:When a reference voltage is fed into a circuit 1 to be measured from a oscillator 4, a sine wave current advanced by phi in the phase flows through the circuit 1. This current is converted into a voltage advanced by phi with an I/V conversion circuit 5. At the points where the phase of the reference voltage is 0 deg. and 180 deg., this voltage shows a voltage ECM corresponding to the peak value of current flowing through a capacitor and a voltage ERM corresponding to the peak value of current flowing through a resistance at the points, 90 deg. and 270 deg.. Then, based on the sum of zero-crossing pulses of ZC detection circuits 12 and 13, a sampling pulse is generated to sample and hold these voltages which are converted into a digital data with an A/D conversion circuit 8. The digital data is processed to calculate the resistance value and the capacity value of the circuit 1.

CONSTITUTION:In case that a mode changing-over switch SW1 and a changing-over switch SW2 are turned on, a switch SW is turned on, resulting in that a relay MC is excited. Each of a relay contact (a1), a time limit contact stored in a timer means T, and a relay contact point (a2) is turned on and then an electrical facility A is turned on. A normal-closed relay contact point (b) is turned off. However, since the changing-over switch SW2 is turned on, an electrical facility B is also turned on. When the switch SW is turned off, the relay MC is deenergized and the relay contact point (a) is turned off, so that the electrical facility A is turned off. Although the relay contact point (a1) is also turned off, the timer means T starts to perform a delaying operation. Its time limit contact point continues its ON-state and if it exceeds a predetermined time, the time limit contact point of the timer means T is also turned off, so that the electrical facility B keeps its ON state. As a time exceeds a predetermined time, the time limit contact point of the timer means T is turned off and then the electrical facility B is also turned off.

Title: Photosemiconductor element
Inventor: UJI TOSHIO
IPC: H01S5/042
Filed: 1983-04-08
Abstract: PURPOSE:To perform the function of controlling a light output in response to a light input by one photosemiconductor element by sequentially forming semiconductor layers having band gap energies Eg1-Eg5 (Eg6, Eg4, Eg3>Eg2<Eg1), the layer of Eg2 is used as a main light emitting layer, and using the layer of Eg4 as a main light absorbing layer. CONSTITUTION:When a current is flowed forwardly to a photosemiconductor element and a light of approx. 1.3mum of wavelength is inputted, the incident light intensity increases, the hole density of the second P type InGaAsP layer 23 increases, a pole femini level approaches to valence element band, and the barrier to the electron of the fourth P type InGaAsP layer 25 increases in height by approx. 100-200meV. As a result, the leakage current gradually decreases, and the light emitting output of the layer 25 increases. This further increases the band-deep level transition in the layer 23 as a positive feedback. Consequently, the light output of 1.3mum abruptly increases to the light input. Then, even if the light input level is gradually reduced, the light output does not immediately decreases, but hysteresis characteristic is exhibited as shown.

Abstract: PURPOSE:To contrive abbreviated dialing with a simple constitution by providing a control section controlling an external dial sending section and sending an external dial signal corresponding to the abbreviated dial from an abbreviation dial memory via the external dial sending section when an extension dials the abbreviated dial number. CONSTITUTION:In dialing from a single telephone set 8, its DTMF signal is detected by an extension dial detection section 9 and an abbreviated dial discrimination section 10 decides whether it is an extension dial, external line acquisition or abbreviated dialing. For example, the external line acquisition is '0' and the abbreviated dial is '*NN' (NN is an abbreviated dial number). When the dial number is '*11', the abbreviated dial deciding section decides it as the abbreviated dialing, a control section 11 turns on a talking link switch 12 and a dial number stored in the abbreviated number '11' is stocked from the abbreviated dial memory 13 to a transmission buffer 14. After a prescribed time from the external line acquisition, the dial number is sent from the external line dial sending section 15 to an external line 16. Thus, dialing is attained by using the abbreviated dial memory from a conventional key signal telephone set 8.

Title: Memory dump collecting system
Inventor: SANO TETSUO
IPC: G06F11/34
Filed: 1989-03-16
Abstract: PURPOSE:To shorten collection time and to compress the size of a collection file by using a partial dump collection means and a total dump collection means by switching corresponding to the type of the abnormal completion of a system. CONSTITUTION:A process execution time registering means 2 registers the final execution time of a process at a process execution time registration table 1. The partial dump collection means 3 collects a memory dump for only a process in which difference between the abnormal completion occurrence time and the final execution time is set within constant time by referring to the table 1. Also, the total dump collection means 4 collects the memory dumps for all the processes. Therefore, for example, in the abnormal completion of the system due to the detection of abnormality by an operating system, the memory dump of only a partial process is collected, thereby, the quantity of memory dump can be reduced. In such a way, the collection time of the memory dump can be shortened, and also, the size of a memory dump collection file can be compressed.
