Patent JP-H05242876-A (JP)
Title: Lead-acid battery
Inventor: SUZUI YASUHIKO
IPC: H01M10/08
Filed: 1992-02-26
Abstract: PURPOSE:To facilitate ocular management of an electrolyte surface by furnishing a film-form separator whose major component is polyethylene, including therein a surface active agent for allowing both ionic and anionic surface active agents to co-exist in the battery, and thereby preventing oil attachment to near the electrolyte surface. CONSTITUTION:A film-form separator contains polyethylene as major component, and both ionic and anionic surface active agents are allowed to co-exist in a battery. Use of such a separator as containing surface active agent for adding these two types of agents is favorable because it permits the omission of a particular surface active agent for reducing the electric resistance. Micell is formed because of this co-existence of the two types of agents, and the quantity of this micell containing the oil being put free from the separator is enhanced synergetically compared with the case where only one is used. This prevents the oil contained in the separator from being put free and attaching to the wall surface of a battery jar in the neighborhood of the electrolyte surface, and management of the electrolyte surface is facilitated.

Title: Waveguide type optical switch
Inventor: IMOTO KATSUYUKI
IPC: G02F1/313
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a waveguide type optical switch with superior crosstalk characteristics which generates no unbalanced light loss even when an optical path is switched. SOLUTION: Optical switching is performed by an X-shaped core pattern, so a small-sized waveguide type optical switch is realized and the propagation loss of core layers 5-1 to 5-4 are reduced. A refractive index control layer 6 which largely varies a refractive index for a small temperature range is used to permit fast optical switching with a low power consumption. An intersection part 12 of the X-shaped core pattern is surrounded with a polymer material having a low refractive index, so that deviations in the insertion loss at the ON/OFF switching time is reduced, and a large extinction ratio can be obtained. Further, optical switch matrices with N-input, M-output (N>=2, M>=4) or M-input, M-output can be formed by combining 2-input, 2-output optical switches.

Abstract: PROBLEM TO BE SOLVED: To enable a temperature sensor formed on a board to be easily corrected on characteristic variability and to accurately sense temperatures. SOLUTION: A temperature sensor 11 and a pull-up resistor 12 are formed together on a board through a thin film process. At this point, the pull-up resistor 12 is structured so as to be changeable in resistance. For instance, one or more fuses 13 connected in parallel with the pull-up resistor 12 are provided.

Title: Semiconductor memory integrated circuit
IPC: G11C29/12
Filed: 1992-02-27
Abstract: PURPOSE:To alleviate the number of general signal terminals and to shorten a testing time by providing a test address generator and a data compressor. CONSTITUTION:In a test mode, a multiplexer 2 inputs a test enable TE. A test address STA to be output from a test address generator 1 is switched to be input to a ROM 3 by a test clock TCK, and test output data STD corresponding to a test address signal is input to a data compressor 4.

Title: Tape cassette
Inventor: KOMIYAMA KOZO
IPC: G11B23/087
Filed: 1990-02-20
Abstract: PURPOSE:To prevent the performance of a tape from deteriorating due to deformation by providing a pawl in such a way that when this pawl of a reel lock is engaged with a ratchet of a tape reel, its tip should be orientated approximately toward the rotational center of the engaged tape reel. CONSTITUTION:The pawl 11 is disposed to be orientated approximately toward the rotational center (o) of the tape reel 2 when force that is enough to deform a tape 3 is given to a lock mechanism consisting of the ratchet 7 provided to the tape reel 2 and the pawl 11 of the reel lock 4. Consequently, the pawl 11 of the reel lock 4 is swung, and hence this force can be released. Therefore, when take-up force on the side of a VTR deck is extremely large, or even when large tension force is given to the tape 3 due to shrinkage of the tape 3, the tape reel 2 can be rotated to a certain extent in the direction of releasing the above force. By this method, the performance is prevented from deteriorating due to deformation caused either by abutting against a guide 8 or by the tape 3 itself.

Title: Reset circuit
Inventor: MATSUZAKI NOBUO
IPC: G06F11/22
Filed: 1991-03-06
Abstract: PURPOSE:To judge the runaway of a CPU that is not detected by a watchdog timer circuit and to initialize the CPU by initializing the CPU when the CPU is no responded within a prescribed time after the reception of an incoming signal. CONSTITUTION:The CPU 7 sends a circuit capturing requesting signal (h) before receiving an incoming signal (a) three times from a network 8 as long as the CPU 7 is normally working. The network 8 stops the transmission of the signal (a) and performs the transfer of data. When the CPU 7 has a runaway, i.e., the CPU 7 is unable to perform its operation despite the reception of the signal (a), a counter circuit 2 counts '3' or more and therefore a reset pulse is outputted to the CPU 7 from an OR circuit 5. Thus the CPU 7 is initialized and works normally again.
