Title: Preparation of n6,9-disubstituted adenine derivative
Inventor: NAGATSU YOSHIROU
IPC: C07B61/00
Filed: 1981-09-30
Abstract: PURPOSE:To prepare the titled compound useful as a coccidiostatic agent, selectively, in high yield, by reacting a metallic salt of N<6>-substituted adenine with benzyl halide. CONSTITUTION:The N<6>-substituted adenine metal salt of formulaI(R is H, 1-4C lower alkyl or 5-7C aralkyl; R' is 1-4C lower alkyl or 5-7C aralkyl; M is alikali metal or alkaline earth metal; n>=1) is made to react with the benzyl halide of formula II (X is Cl or Br; Y and Z are H, Cl, Br, or F) in the presence of a phase transfer catalyst[e.g. the quaternary ammonium salt of formula III (R1-R3 are 1-18C alkyl; R4 is 1-10C alkyl, etc.; X is OH, etc.), etc.]to obtain the objective 9-substituted compound. By the use of the metallic salt of formulaIas a starting raw material, the production of the 3-substituted compound of formula V can be suppressed, and the selectivity of the 9-substituted compound can be increased. The presence of the phase transfer catalyst increases the rate of the main reaction, and prevents the side reactions.

Abstract: PROBLEM TO BE SOLVED: To widen the acquisition width of a light phase locked loop (light PLL) by synchronizing the light phase of laser light (output light) outputted by a laser light source with the light phase of the carrier component of signal light (input light) inputted from outside. SOLUTION: The semiconductor laser light source 21 has a nonlinear optical medium 22 and a semiconductor optical amplification part 23 integrated and power sources 24-1 and 24-2 are connected thereto respectively. The output light of the semiconductor laser light source 21 is partially demultiplexed for feedback through an optical demultiplexer 25.

Title: Measuring method for deformation
Inventor: TAKEMORI TAMIKI
IPC: G01B11/16
Filed: 1988-06-22
Abstract: PURPOSE:To eliminate the need to align the moving direction of a speckle pattern and the axis of a photodetecting element array by employing a stripe type as the respective elements in the photodetecting element array which performs photoelectric conversion. CONSTITUTION:The speckle pattern obtained by irradiating the measurement area O of a body 10 with a laser beam 13 is photodetected by the photodetecting element array 20 which constitutes a linear image sensor arranged on an observation surface 30 and converted photoelectrically. In this case, the respective photodetecting elements (22n-1, 22n, 22n+1...) of the element array 20 are formed in a stripe shape which has, for example, a 13mum short side and a 2.5mm long side. Consequently, the majority of the outputs of the elements after moving in the (y)-axial direction of the element array 20 are outputs which are proportional to the element area of the light intensity of the speckle pattern before the movement. Therefore, when the element array 20 is formed in the stripe shape to increase the photodetection area, the quantity of light outside the photodetection range of the elements and the quantity of light which is newly entered are equal in the uniformity of the outputs and even when the movement quantity is large, output variation is reduced.

Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To provide a new circuit by which a 1st read cycle is started at the time point when a power has been firstly applied to a memory device. SOLUTION: A circuit compares the rise of a word line voltage signal with a stable reference voltage by using a comparator. When the work line voltage reaches a predetermined level but before the voltage reaches a maximum value, the comparator is operated. The transition of the comparator output is detected by address transition detection circuits 12 and 14 which trigger the read cycle of a memory after that and a dummy read access is produced while it is not necessary at all to transit an input address actually. After one memory access time, the effective data in the output of a memory array can be utilized. In order to divide the word line voltage into a level suitable for the input to the comparator, a voldage divider is used.

Title: Hot water room heater
Inventor: ITO TERUAKI
IPC: F24D3/00
Filed: 1989-06-16
Abstract: PURPOSE:To reduce a running cost and to increase the lifetime of a hot water circulation pump by providing a controller for intermittently operating the pump CONSTITUTION:A Combustion controller 16 and a pump controller 17 start operating upon closing of an operation switch 11. The controller 16 turns a burner 2 'ON' 2a and 'OFF' 2b in response to the detection temperature 10a of a hot water temperature thermostat 10. The controller 17 repeats to forcibly turn a circulation pump 4 'ON' 4a for predetermined time t1 and to then forcibly turn it 'OFF' 4b up to time t2, thereby intermittently operating it. The periods and conducting times of the 'ON', 'OFF' can be switched by a manual switch 15. Thus, the conducting time of the pump is reduced to conserve the power and to increase its lifetime. Particularly in a large-sized system having many chambers to be heated and many branches, power can be largely conserved when low load operation of one or two chambers (by closing the other chambers) is executed.
