Patent JP-H0220907-A (JP)
Title: Light reception use amplifier circuit
Inventor: OSADA RYOICHI
IPC: H03F3/08
Filed: 1988-07-09
Abstract: PURPOSE:To prevent a drop of the maximum light reception level by detecting an ascent of a DC output voltage of amplifier caused by an increase of a light input level by a voltage comparator having a hysteresis, allowing a transistor to conduct in case the voltage is lower than a reference voltage, and bringing the transistor to nonconducting in case the voltage is higher. CONSTITUTION:An input light is converted to a current by a photodiode 1, and amplified by a field effect transistor 3 and an amplifier 9. An output DC voltage of the amplifier 9 is detected by a voltage comparator 14 having a hysteresis, a transistor 6 becomes conducting or nonconducting by an output of the voltage comparator 14, and an amplification factor of the field effect transistor 3 is controlled. That is, in case a light reception level is small, an output voltage from the amplifier 9 becomes smaller than a reference voltage and the output of the voltage comparator 14 becomes a high level, and the amplification factor of the field effect transistor 3 becomes high. On the other hand, in case a light input level is high, the output of the voltage comparator 14 becomes a low level. As a result, the amplification factor of the field effect transistor 3 becomes small. In such a way, a drop of the maximum light receiving level can be prevented.

Title: Data transmitter
Inventor: KAWAHARA KUNIHIKO
IPC: H04L29/08
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To improve throughput by allowing the transmitter to recognize erroneous data without processing by a CPU of a higher level, so as to relieve the load on the CPU. SOLUTION: Transmission data 51, sent from the transmitter are given to a transmitter side data control section 11, a transmitter side frame check sequence FCS calculation section 12 and a selection section 13. The transmitter side FCS calculation section 12 calculates as FCS 53, based on the transmission data 51. In the case that the transmitter side data control section 11 discriminates it that transmission data have an error, the control section 11 uses an inverted control signal 61 to control an inverter section 14 for providing an output of the inverted FCS. The selection section 13 selects the transmission data 51 or an inverter section output 62 (inverted or noninverted FCS) and transmits the selected data to network 3 as output data 52.  On the other hand, a receiver side FCS calculation section 22 extracts the FCS from received data 58 and outputs FCS confirmation data 56 to a receiver side data control section 21. The receiver side data control section 21 outputs an error signal 57 of the received data according to the confirmation data 56.

Title: Error correction device for read-in data
Inventor: NIIMURA YOSHITO
IPC: G11B20/18
Filed: 1990-06-29
Abstract: PURPOSE:To efficiently use a read-in data which did not generate an error by continuing a read-in when an error is generated during the data read-in while temporarily storing that store address, underacting the data of the stored store address after executing the data read-in again. CONSTITUTION:A data storing means 1 stores the data read from a tape recorder to be externally connected, and a detecting means detects the error in the read-in data. An address storing means 3 stores the store address of the data storing means 1 of the read-in data including the error detected by the detecting means 2, and a correcting means 4 corrects the data stored in the data storing means 1 to a re-read-in data following the address stored in the address storing means 3 when the reproduced data is read in. Thus, unless there is an error of the storage data itself where noise is generated continuously at the same address at the time of data read-in, the error of the read-in data by the noise, etc., at the time of data read-in can be corrected.

Title: Nonaqueous electrolyte battery
Inventor: ISHIBASHI CHIKANORI
IPC: H01M6/14
Filed: 1989-06-30
Abstract: PURPOSE:To retard increase in internal resistance and open circuit voltage and to increase storage performance by forming a mixed alloy layer with aluminium on the surface of a lithium alloy negative electrode comprising a specific metal element and lithium and by facing the mixed alloy layer toward a positive electrode. CONSTITUTION:A mixed alloy layer alloyed with aluminium is formed on the surface of a lithium alloy negative electrode and faced to a positive electrode. The surface area of the negative electrode is increased and internal resistance of a battery is decreased. The formation of a film on the surface of the negative electrode caused by moisture penetrated into the battery during storage is retarded by the mixed alloy layer. As a result, increase in internal resistance is prevented. Since the lithium alloy comprising lithium and at least one metal element selected from the group comprising In, Mg, Sn, Pd, Zn, Pb, Ni, Ag, and Ca is used, increase in open circuit voltage caused by making its potential noble can be retarded.

Title: Alarm circuit for deficient light receiving quantity
Inventor: OIMURA KATSUHIKO
IPC: H04B10/07
Filed: 1986-07-17
Abstract: PURPOSE:To offer a countermeasure such as checking of an optical connector by raising an alarm as the deficient light receiving quantity when a prescribed amount or over of pulse signal attended with a high frequency noise is outputted at an output of an optical receiver after a count means is reset. CONSTITUTION:If the luminous quantity of an optical signal inputted to the optical receiver 1 is deficient, an amplifier in the optical receiver 1 outputs a signal superimposed on the high frequency noise. When the level of the high frequency noise reaches nearly the same level as the reference level, lots of pulse signals are outputted in 1-bit time width in the output of the optical receiver 1 because of the high frequency noise. On the other hand, a counter 6 counts the pulse signal when the pulse signal attended with the high frequency noise is outputted from the optical receiver 1 while the clock pulse generated from a clock pulse generating circuit 4 is at an L level as shown in figure (c). When the counter 6 counts three pulse signals outputted from the optical receiver 1, an H level light receiving quantity deficiency detecting signal is outputted from its output terminal Y1.

Title: Charger for battery of vehicle
Inventor: TAKADA NAOYA
IPC: H02J7/16
Filed: 1990-06-27
Abstract: PURPOSE:To prevent the wasteful power consumption resulting from battery deterioration by judging it that the battery has deteriorated when the voltage difference between an alternator and the battery is over the set value for a certain period, and lowering the alternator voltage so as to approximate it to battery voltage. CONSTITUTION:A regulator 10 makes the alternator voltage follow the target value by feedback control when a battery is not deteriorated yet, and changes the target value over to high or low according to the signal form a control unit 30. And if the voltage difference between the alternator voltage Va and the battery voltage Vb, V=Va-Vb, is not less than a set value,  V>= set value, there is possibility of the battery 11 having deteriorated, so it follows that, if the difference between the reference voltage  Vo at some point of time and the voltage difference  V after ten seconds,  Vo- V, is positive on comparison, the battery voltage Vb is not restored even if charged, so it judges it that the battery 11 has deteriorated. And under the condition of high control operation, the target value of alternator voltage is set to the proper value a little higher than the battery voltage Vb, and the useless charge from the alternator 7 to the battery 11 is prevented.

Abstract: PURPOSE:To achieve muting for a sufficient time including the time when a circuit is stabilized by alternating recording and reproduction according to the sum of the time from the closure of a trigger switch to the muting of a detection switch and the time until the flip-flop circuit is reset. CONSTITUTION:With a recording button pushed, a switch 6 is closed in a short time to turn on a control transistor (TR) 20, and the output of the 1st comparing circuit 9 makes the output of a flip-flop circuit 8 go down to a level L to turn on a TR14, thereby starting muting operation. At the same time, a TR16 turns off to start the charging of a capacitor 18. Then, a detection switch 19 is short- circuited to charge the capacitor 18 to the earth potential, and the switch 19 is reset to start the charging of the capacitor 18 again. Then when the 2nd comparing circuit 10 generates an output H, a signal is applied to the reset terminal of the flip-flop circuit 8 to turn off the TR14, resetting the muting state.
