Title: Transmission and reception module for array antenna and array antenna device using the same
Inventor: KAJIWARA KOJI
IPC: H04B1/40
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a transmission and reception module of an array antenna and an array antenna device using the same, which dispenses with transmission and reception of high frequency transmission and reception signal regarding a transmission and reception module, and can simplify a structure up to the transmission and reception module. SOLUTION: This device is equipped with memories 8a to 8n for outputting digital data which become original oscillation of a local signal, data converters 9a to 9n for offsetting the digital data, D/A converters 10a to 10n for converting the digital data into analog signals, frequency converters 11a to 11n for converting into required local signal frequencies, and mixers 7a to 7n for having the local signal converted between a high frequency signal and an intermediate frequency signal.  For this device, since this local signal is generated inside a transmission and reception module, supply of the high frequency signal for the local signal becomes unnecessary from the outside, and at the same time, it becomes possible to have the high frequency signal of a transmission and reception signal converted into the intermediate frequency signal by the mixers 7a to 7n and to have the intermediate frequency signal converted into the high frequency signals by the mixers 7a to 7n. Thus, effects can be obtained such that the power feeding of the transmission and reception signal to the transmission and reception module can be performed through an interface by the intermediate frequency signal.

Title: Semiconductor memory device
Inventor: AKIBA TAKESADA
IPC: G11C11/41
Filed: 1988-03-23
Abstract: PURPOSE:To reduce the increase in chip dimension and delay in memory operation of the tile device so as to constitute the device in a highly integrated state by dividing data output amplifier groups provided at every divided sub-input/output line into two sets and arranging them on both sides of a memory array closely to the memory array as if the memory array is put between the amplifier groups. CONSTITUTION:A very small potential difference is produced in a data line depending upon the information accumulated in memory cells MC. After the potential difference is amplified by means of a sense amplifier, the output line of a decoder YD becomes high in level and the information of the data line is read out to a data output amplifier AMP through a sub-input/output line. When, for example, the Y-decoder output line in the lower section of a sub-array is selected by the decoder YD, the information of the data line is read out to the data output amplifier AMP in the lower section of this chip through a sub-input/output line IPb. Since the data output amplifiers are arranged above and beneath the memory array in such way, lengths of the wirings connecting the sub-input/output lines with the data output amplifiers become shorter. Therefore, the parasitic capacities and resistances can be reduced and the operating speed of this memory can be improved.

Title: Spectrophotometer
Inventor: HIROSE HIROSHI
IPC: G01J3/443
Filed: 1978-06-07
Abstract: PURPOSE:To record spectra always at an optimum gain with high accuracy by automatically changing over the gain of a photelectric signal amplifier according to the intensity of photoelectric signal. CONSTITUTION:Light signal out from a spectroscope 1 is converted to a photoelectric signal by a photo detector 2. After this signal is amplified with a multistage gain amplifier 3, it is converted to a digital signal by an AD converter 4. This signal enters a bus line 11. A CPU 6 compares the signal from the AD converter 4 with the reference value H of a memory 7 and emits the control signal to an amplifier gain controller 5 through the bus line 11 so as to lower the amplifier gain when the signal is larger than H. If the signal is not larger than H, the CPU compares the same with another reference value L and when it is smaller than L, the CPU emits the control signal to the gain controller 5 so as to increase the gain. If the signal is between H and L, the CPU multiplies the signal by a coefficient inversely proportional to the amplifier gain to let the magnitude of the signal be proportional approximately to the mecha photoelectric signal. This signal is outputted to a DA converter 9 and is recorded in a recorder 10.
