Title: Frequency synthesizer
Inventor: ADACHI HISASHI
IPC: H03L7/183
Filed: 1994-06-15
Abstract: PURPOSE:To reduce spurious at a point near the center frequency of an output signal for a frequency synthesizer which controls the frequency of the output signal at an interval smaller than that of the frequency of a reference signal. CONSTITUTION:A dividing ratio control circuit 5 consists of the accumulators 6-9 which are connected to each other in multiple stages, and a mantissa part calculation circuit 10 which changes the dividing rate by the carry signals received from the accumulators 6-9. Thus the dividing ratio of a variable divider 2 of a phase locked loop varies approximately for each clock. Then '1' is added to the lowest order bit of the accumulator 7 for each clock so that the changing cycle of the dividing rate is varied. Thus the spurious can drastically be reduced at a point near the center frequency of an output signal.

Title: Heat exchanger for recovering heat of blow water
Inventor: SHIRAISHI HITOSHI
IPC: F28D1/06
Filed: 1981-08-25
Abstract: PURPOSE:To provide a heat exchanger with a lightweight, compact and highly efficient construction without inducing any problems on pressure resistance, by a method wherein a heat exchanger is constructed by disposing a star-shaped heat-exchanging body made of a sheet in a container. CONSTITUTION:The heat exchanger 1 is constructed by placing the heat-exchanging body 8 in the container, wherein the container is composed of an outer drum provided with an inlet pipe 14 and an outlet pipe 15 for feed water and end plates 13, and the heat-exchanging body 8 comprises an inlet pipe 10 and an outlet pipe 11 for blow water provided respectively at header plates 9, 9 at both ends thereof. The body 8 is produced by bending a sheet into a star shape. In using the heat exchanger 1, for example, the blow water from a boiler is passed through the interior of the body 8, while feed water is passed on the outside of the body 8. Accordingly, little pressure difference is generated between the inside and the outside of the body 8, so that no problem arises as to the pressure resistance even when the body 8 is made from a thin sheet. In addition, since a sufficiently large heat-transmitting area can be provided by bending the sheet into the star shape, a compact and highly efficient heat exchanger can be obtained.

Filed: 1989-05-26
Abstract: PURPOSE:To make the flow speed distribution at a detecting part steady and to make it possible to perform highly accurate measurement by arranging a member for disturbing a flow at the end part of a fluid inlet port in the axial direction of a measuring tube, and imparting the flow speed distribution of forcibly disturbed flow to a detecting part all the time. CONSTITUTION:The inner diameter of a grounding ring 1A on the side of a fluid inlet port is made smaller than the inner diameter of a lining 3 of a measuring tube 5 by about 5 - 10%, and a member for disturbing a flow is provided. The flow speed distribution of a fluid flowing through the inside of the lining 3 is forcibly disturbed by the action of the grounding ring 1A. The inherent flow speed distribution is always maintained, and the effect of the state of a mate pipe 6 is not imparted to the detecting part of a detector main body 4. Therefore, stable, highly accurate characteristics can be maintained. In this way, the effect of the disturbance in flow speed distribution generated by the deviation of the mate pipe 6 can be blocked even for a detector whose surface is made short. The highly accurate measurement can be performed. Furthermore, the length of the straight pipe of the object pipe 6 can be made short.
