Title: Semiconductor light detector
Inventor: YAMAMOTO AKINAGA
IPC: H01L31/10
Filed: 1988-01-28
Abstract: PURPOSE:To make it possible to read out a signal charge rapidly and stably without unread charge even in the case of a sudden change of the amount of incidence of light exposure, by making an optical signal reader by the use of a junctiongate-type FET. CONSTITUTION:When an address signal S is applied to an n-type semiconductor layer 23, a gate of a junction gate-type FET 26, at the level of H, a p-n junction made of the layer 23 and p-type semiconductor layers 21, 22 and 24 is biased in the reverse direction and a depletion layer spreads out in the layer 24. Therefore, a signal charge photoelectrically converted by a photo diode 25 is temporarily stored in a photo diode junction capacitance 27. When the signal S sent via a signal line 9 is applied to the gate (layer 23) of the FET 26 under this condition, a signal charge channel is formed since the reverse bias applied to the p-n junction is reduced and the depletion layer spread out in the layer 24 gets smaller. Because of this, the signal charge which has been stored in the capacitance 27 is sent forth into the layer 21 and starts flowing into a load resistance 12. Therefore, a rapid read-out of an optical signal is available.

Title: Lithium secondary battery
Inventor: HORIIE HIROSHI
IPC: H01M10/052
Filed: 1989-01-27
Abstract: PURPOSE:To suppress self-charge and obtain a satisfactory battery performance by forming a positive electrode by a conductive polymer, and forming at least the whole surface made in contact with the positive electrode of a positive electrode collecting plate by metal titanium. CONSTITUTION:A positive electrode 4 is formed of a conductive polymer, and at least the whole surface made in contact with the positive electrode 4 of a positive electrode collecting plate 1 is formed of metal titanium. Thus, even if the potential difference between both electrodes 4, 5 is reached to a high voltage of 3.5V or more at the time of charging, the conductive polymer maintains the oxidized state. Hence, a self-charge caused by the conversion of the conductive polymer into the reduction state under high voltage is significantly suppressed, and a lithium secondary battery having excellent battery characteristics such as discharge capacity and open-circuit voltage can be obtained.

IPC: H04J3/14
Filed: 1987-01-28
Abstract: PURPOSE:To multiplex a digital signal including data strings having different bit rate speed as much as possible, by varying the delay word length of a delay means which decides the leading position of the digital signal to be multiplexed based on the word length information of the leading position to be multiplexed. CONSTITUTION:The input terminals 1-4 of the signals to be multiplexed, that are the digital signals to be multiplexed, are connected to a first and a fourth variable word length shift registers 6-9, respectively, and each of the variable word length shift registers 6-9 is connected to an AND gate 15, and is connected to an output terminal 5. A control circuit 10 is connected sequentially to a fourth serial-parallel conversion circuit 14, a third serial-parallel conversion circuit 13, a second serial-parallel conversion circuit 12, and a first serial-parallel conversion circuit 11. Thus, since the delay word length of the delay means which decides the leading position of the signal to be multiplexed is varied based on the word length information at the leading position of the signal to be multiplexed, it is possible to designate the leading position of a data signal to be multiplexed at any position. Therefore, it is possible to multiplex the digital signal including the data strings having different bit rate speed as much as possible.
