Title: Improvement of pcr
Inventor: UIRU BUROTSUKU
IPC: C12Q1/68
Filed: 1992-07-23
Abstract: PURPOSE: To improve the accuracy and specificity of in situ PCR by withdrawing a subset of PCR reagents from a cellular preparation until the cellular preparation is heated up to the temperature region of immddiately before the start of the thermal cycling.  
     CONSTITUTION: The present invention is achieved by withdrawing a subset of PCR reagents from a fixed cellular preparation until the cellular preparation is heated up to 50-80°C, immediately before the start of the thermal cycling. In stead of the withdrawal of the subset of PCR reagents, a single stranded DNA binding protein, which blocks the reaction, may be added to the PCR reagents while the temperature is ≤50°C.

A hysteresis is given to the reaction voltage at the time of boosting the depression signal from the key matrix 3 to a prescribed voltage, and a RAM 9 is used to change this hysteresis, and then, the key depression signal is outputted to the host computer after being sampled twice. Consequently, chattering is prevented, and reaction is possible only in the transmission time of each circuit. Thus, the processing time is shortened.

It is desirable that the mean molecular weight of the vinyl chloride group copolymer is brought to approximately ten or one hundred thousands, the physical properties of the ink layer are deteriorated and the dye cannot be held firmly when the mean molecular weight is lower than said values, and the viscosity of paints for forming the ink layer is too high when the mean molecular weight is larger than said values.

Abstract: PURPOSE:To present distance measuring capacity from being influenced by temperature by changing a voltage ratio at which APD bias voltage is decreased from breakdown voltage in accordance with ambient temperature. CONSTITUTION:An APD 15 converts a laser beam reflected from an object into pulselike electric signals. When bias voltage is high and a breakdown phenomenon of the APD 15 occurs, a timing signal, of a breakdown detecting circuit 17 and charging of a charging capacitor 20 from a FET 12 and a diode 14 are stopped so that the ADP bias voltage is held lower than the breakdown voltage. On the other hand the lower the temperature is, the larger an optimum fall voltage ratio is. The optimum bias setting suitable for the ambient temperature can be performed by matching the voltage fall ratio with the characteristics and performing control to decrease the voltage from the breakdown voltage. A FET 13, a temperature control pulse generating circuit 18 and discharging resistance 19 perform the voltage fall operation.

IPC: G06F15/173
Filed: 1989-09-18
Abstract: PURPOSE:To perform the highly efficient broadcast communication to the node that designated a range by deciding the distance between nodes based on the address information, deciding the data transmission direction based on the distance information, and transmitting the data whose addresses are decided in each direction. CONSTITUTION:The data received from other nodes are received by the -X direction reception processing parts 11 - 1N and 21 - 2N in each direction. The address information designated by an address detecting part 3 is detected, and an inter-node distance processing part 4 obtains an inter-node distance based on the address information. An address deciding part 5 decides whether the data should be fetched to its own node or not to fetch the data and at the same time decides the direction where the data is sent next based on a fact whether the inter-node distance is equal to zero or not. Then the data are transferred to the +X direction transmission processing parts 61 - 6N and 71 - 7N in each direction. These transmission processing parts transmit the data received from the part 5 via the nodes. Thus it is possible to perform the broadcast communication with high efficiency in a designated range.
