Title: Photo detector
Inventor: ICHIHARA FUMIO
IPC: H04N17/04
Filed: 1978-06-07
Abstract: PURPOSE:To improve the resolution of position detection by providing a gate circuit by providing a gate circuit which samples the detection signal of a detecting circuit by the sampling pulses of a width smaller than the time intervals of scanning between luminescence spots. CONSTITUTION:In the apparatus of detecting the luminescence spots of, e.g., a braun tube, and obtaining the signal of its detection position, a gate circuit 3 is provided between a detecting circuit 1 and the terminal 8 of the output circuit of the detecting signal and the sampling pulses coinciding with the point to be detected and of a pulse width smaller than the time intervals of scanning between the detection points are applied to this gate circuit 3. The detection signals are sampled by these sampling pulses. For example, the photo detecting signal having been inputted to the gate circuit 3 is outputted as the position detecting signal from the output terminals 8 only when the vertical and horizontal pulse signals PV, PH are applied, and therefore even if the detection range I overlaps the adjoining luminescence points A, the outputs of both positions cannot be obtained unless it is across the detecting regions encircled by the broken lines of a width l.

Title: Method for controlling inclusion in steel for electronic material
Inventor: HITOMI YASUO
IPC: C21C7/00
Filed: 1986-03-27
Abstract: PURPOSE:To manufacture a steel for an electronic material having satisfactory workability and suitability to plating by regulating the temp. of a molten steel during refining and casting and by using a refractory contg. no MgO as the refractory of each of refining and casting vessels so as to reduce the amount of hardly workable inclusions. CONSTITUTION:When a steel for an electronic material is manufactured, the maximum temp. of a molten steel in a refining vessel during refining is regulated to <=1,700 deg.C to inhibit the enrichment of inclusions by the erosion of the lining refractory of the vessel. The superheating temp. of the molten steel in a tundish for casting including continuous casting is kept at such a high temp. as >=40 deg.C to accelerate the floating and separation of coarse inclusions. A refractory contg. no MgO such as an SiO2- or ZrO2-base refractory is used as the refractory of each of the refining and casting vessels so as to reduce the amount of hardly workable MgO-base inclusions.

Title: Lock system
Inventor: BENGUTO UURENFUARUKU
IPC: E05B49/00
Filed: 1984-04-06
Abstract: The invention relates to a lock system for rooms which are to be made exclusively accessible to different uses over different periods of time, for example hotel rooms. The keys of the system comprise magnetic cards which are provided with magnetically registered data, which for each card includes lock-identification data valid for a given lock or a given group of locks, a validity time expressed in real time and a randomly selected legitimacy code. Each lock includes an electrically actuable lock mechanism (4), a magnetic-card reader (3), a memory (6) for the storage of data, a real-time clock (7), a programming unit (10), a legitimacy comparator (8), and a time comparator (9). The memory (6) has stored therein the lock-identification data valid for the lock. When a magnetic card is introduced for the first time into the card reader (3) of a lock, the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory (6), and the time comparator (9) compares the validity time registered on the card with the real time given by the real-time clock (7). If these comparisons show agreement, the lock opens and the programming unit (10) is instructed to store into the memory the validity time and the legitimacy code registered on the card. When a magnetic card is later introduced to the card reader (3) the time comparator compares the real time given by the real-time clock (7) with the validity time in the card data stored in the memory and the legitimacy comparator (8) compares the data registered on the card with the data stored in the memory (6) of the lock, and the lock is opened when agreement is found between the data compared. If the comparison made by the time comparator (9) show disagreement, the time comparator compares the validity time registered on the card with the real time given by the real-time clock (7) and the legitimacy comparator (8) compares the lock-identification data registered on the card with the lock-identification data stored in the memory and, if these comparisons show agreement, the lock is opened and the programming unit (10) is used to replace the card data already stored in the memory (6) with the data registered on the card.
