Title: Cooling apparatus for wall of reactor vessel
Inventor: HIRAYAMA HIROSHI
IPC: G21C15/12
Filed: 1989-11-30
Abstract: PURPOSE:To obtain high cooling effect and to make a heat insulating material thin by providing a heat radiation accelerating mechanism for accelerating the heat radiation from a safety vessel to the inner surface of a heat insulating material cover. CONSTITUTION:Since a large number of fins 19 are integrally provided to the inner surface of a heat insulating material cover 18, the heat insulating material cover 18 is rapidly and well cooled by the air streams due to air conditioning ducts 16, 17 and the temp. thereof falls. Since the heat radiation from a safe vessel 10 to the heat insulating material cover 18 increases in direct proportion to the fourth power of the temp. difference between the safety vessel 10 and the heat insulating material cover 18, the heat transfer due to radiation increases to a large extent when the temp. of the heat insulating material cover 18 falls and the removal of heat from the safety vessel 10 is accelerated. Therefore, high cooling effect is obtained in the same air flow rate. Further, since the temp. of the heat insulating material cover 18 is lowered, a heat insulating material can be made thin without being accompanied by the temp. rise of the cavity wall 11 of a nuclear reactor.

IPC: G11B7/135
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To solve a reflection problem of incident light by offsetting a light receiving element by a prescribed distance in a plane vertical to a normal at point of incidence with respect to the normal of the light to be detected prescribed in a refraction layer, refracting the light to be detected made incident on the refraction layer in the refraction layer with respect to its offset amount and receiving the light on the light receiving surface of the light receiving element. SOLUTION: The offset amount of a photodiode 14 against the normal X at point of incidence is made so that the main light made incident on the refraction layers 18, 20 is refracted by the refraction layers 18, 20 and received on the light receiving surface of the photodiode 14. This offset amount ΔS is defined by the equation: ΔS=t.tan(θ') [θ'=sin<-1> (n/n.sin(θ))] wherein (θ is the incident angle of the main light, (n) is the refractive index of the refraction layers 18, 20, (t) is the distance from the incident point of the main light to the refraction layers 18, 20 to the surface containing the light receiving surface of the photodiode 14 along the incident normal X). Thus, the reflection light isn't returned to a main light direction, and a stray light problem doesn't occur without adding a cost.

Patent JP-H04182834-A (JP)
Title: Information processor
Inventor: FUKUOKA KATSUTO
IPC: G06F9/48
Filed: 1990-11-19
Abstract: PURPOSE:To prevent the function of a main processor from being wasted in the processing of an external interruption handler by performing simple interruption processing by a subordinate processor independently and executing an interruption task on a main processor for complicate interruption processing. CONSTITUTION:In the information processor COM1, the main processor MPU executes a normal task MTSK unless an external interruption signal INT is inputted, but the subordinate processor SPU stops its execution. When the signal INT is inputted, the processor SPU starts the execution of the external interruption handler ISR and stops again when the execution of the handler ISR ends. The processor SPU operates independently of the processor MPU, which continues to operate while the processor SPU operates. Therefore, the handler ISR operates on the independent processor SPU, so registers used by the handler ISR hold their contents at the head of the handler ISR and the contents of the registers need not be reset at the end.

Title: Light detection
Inventor: ITO YUICHIRO
IPC: H01L31/0264
Filed: 1988-12-08
Abstract: PURPOSE:To obtain a light detection method without crosstalk generated between pixel areas by performing a photoelectric conversion utilizing a Schottkey junction and an avalanche effect by a large reverse bias. CONSTITUTION:A reverse bias is applied to a Schottkey junction with a p-type or n-type semiconductor layer 2 and a metal film 1. Then, an electric charge injected into a semiconductor layer 2 bulk from the metal film 1 undergoes an avalanche multiplication with the incidence of light. This keeps an electric charge generated in one pixel area from flowing to the other pixel area thereby checking the generation of a crosstalk.

Title: Balance adjusting circuit
Inventor: YAMADA SUSUMU
IPC: H04S7/00
Filed: 1990-11-16
Abstract: PURPOSE:To cancel balance adjustment immediately after a non-adjustment period continues for more than a prescribed period by forming a count circuit as an up/down type and discriminating a count direction and an initial value with the initial value as the intermediate value of a count range. CONSTITUTION:An up/down type count circuit 19 is provided to execute counting and to set the initial value at the intermediate value of the count range with the output signal of an oscillation circuit 16 as a clock. Since it can be discriminated whether the count direction is up or down to the initial value only by observing whether the most-significant bit of the count value of this count circuit 19 is '0' or '1', the count value of the count circuit 19 is gradually changed toward the initial value. When it is detected that the count value returns to the initial value, the count operation of the count circuit 19 is stopped. Thus, when the non-adjustment period continues for more than the prescribed value, the balance adjustment can be immediately canceled.

SOLUTION: A hollow pile main body 2 is connected to a bottom surface of an upper structure 1, and the lower end of a rod-shaped axial tension transmitting body 3 whose upper end is connected to the upper structure 1, is fixed to a partition wall 4 arranged inside the pile main body 2. A vertical load P from the upper structure 1 is distributed according to the vertical rigidity ratio of the pile main body 2 to the axial tension transmitting body 3, and a vertical load of P is transmitted to the pile main body 2, and P is transmitted to the axial tension transmitting body 3. A distributed load P from the axial tension transmitting body 3 merges in an arranging position of the partition wall 4, but reduces by a quantity of resultant force F of peripheral frictional force in a lower end fixing place of the axial tension transmitting body 3.  Therefore, maximum compressive force generated in the pile main body 2 becomes P in a pile head or (P+P-F) in a lower end fixing place of the axial tension transmitting body 3.
