Title: Hand cutter and chain saw using reduction device of planetary gear
Inventor: TANAKA HIROSHI
IPC: B27B17/00
Filed: 1990-01-26
Abstract: PURPOSE:To keep a balance which is capable of applying force to blade edge to be obtained, while the eccentric distance between a motion-transferring mechanism and a tool body-supporting point is shortened, and the device is made compact as a whole by providing the final output ring which receives the planetary motion of the planetary gear which constitutes a sun gear as reduced rotary motion at the position which surrounds an original driving shaft and in the inside of the sun gear. CONSTITUTION:Since the planetary gears 5 which constitute sun gears 4 achieve planetary motion, while they enclose the central parts of the sun gears 4, the final output ring 7 which surrounds an original driving shaft 1 may be reducibly rotated through the shaft 10 which supports the planetary gear 5. Since the final output ring 7 acts also as a pully 6, it transfers its rotary force to the side of a cutter-fixing shaft 2, while a belt 3 is used as an intermediate ring. Consequently, the reduction device may be intensively made light and compact, and the light and fatigueless tool may be obtained, though it has the reduction device.

Abstract: PURPOSE: To perform insulation-separation by the method wherein a non-single crystal layer is formed selectively on a semiconductor substrate and thereby a polycrystalline layer is formed, and oxidization is operated after diffusing an impurity.  
     CONSTITUTION: Si 3 N 4  film 23 is provided adjacent to n +  buried-in layer 22 on p - -type Si substrate 21, and n epitaxial layer 24 and poly-Si layer 25 are grown. When high-pressure oxidization is performed after diffusion of p on the entire surface, due to the differences in diffusion speed and oxidation speed, layer 25 is converted into SiO 2  layer 27, and since the oxidation speed is high, no unwanted diffusion occurs, so that high-density separation can be done; and at the same time, no large distortion occurs as in the case of Si single crystal oxidation, and a thick insulation-separation can be done. By opening SiO 2  film 28 on the upper surface, N-layer 30 is formed. Using SiO 2  film 31 as a mask, oxidization is operated; and layers 30 and 32 are connected and oxide layer 33 and p layer 35 are formed. Next, using SiO 2  film 36 and Si 3 N 4  film 37 as masks, SiO 2  film 38 n + -type layer 39 are formed in succession, and electrodes 39W41 are provided. By this structure, a high- density IC can be formed.

Title: Processor load decentralization system
Inventor: KUBOTA MASAFUMI
IPC: G06F15/177
Filed: 1991-02-08
Abstract: PURPOSE:To improve the throughput of a processor and to shorten the waiting time in a congestion state. CONSTITUTION:A processor control part 11 always monitors the congestion state of a processor 10 of a working system. A load decentralization rate of the substitute processing is previously set at a memory 12 of the part 11 against a processor 20 of a stand-by system. When the load of the processor 10 reaches a prescribed reference level set at the memory 12, the part 11 instructs a line switching part 30 via the processor 10 to perform the substitute processing for the processor 20 and at the same time asks the processor 20 for the substitute processing. Thus the processor 20 controls the part 30 and carries out the substitute processing.

Title: Communication device
Inventor: IKEDA NORIHIRO
IPC: H04M1/00
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a communication device which selects a transfer destination that has high possibility that the other party responds when plural transfer destinations are selected to execute trunk line-trunk line transfer service and obtains efficient transfer processing. SOLUTION: When a main device 101 of a communication device executes trunk line-trunk line transfer service, the device 101 partially or entirely changes a calling number to a 2nd transfer destination when a 1st transfer destination does not respond, and executes transfer processing. And it repeats the transfer operation until the other party responds and stores the opposite transfer destination number which finally responds. When the next trunk line-trunk line transfer service is executed, the device 101 preferentially uses the stored transfer destination number. Also, it restores the response count and failure count of the past transfer processing and they are used for decision conditions at the time of selecting a transfer destination number.

CONSTITUTION:The threshold value level and trigger condition of an input signal are set to an input signal comparator 1a and a trigger control circuit 1e from an operation panel 3 and the present date is set to a timer input control circuit 6b to start a timer 6a and, further, the trigger setting date is set. When the clocking of the timer 6a reaches the trigger setting date, the circuit 1e becomes an enable state to monitor the generation of a trigger condition on the basis of a predetermined input signal. When the trigger condition is generated, a trigger signal is outputted to a memory control circuit 1b. By this method, the signal state for a predetermined period before/after the generation data of the trigger condition is stored in a memory 1d and the generation date of the trigger condition is stored in a buffer 7. The stored signal state and the stored generation date of the trigger condition are synchronously read by the circuit 1b to be displayed on a display 4 through an output signal generator 1g.

IPC: G11B19/16
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk player which reduces the number of indication keys and eliminates misoperations.

Title: Heat accumulator
Inventor: UNO HIROSHI
IPC: F24H7/00
Filed: 1984-02-03
Abstract: PURPOSE:To prevent generation of a supercooling phenomenon, by making a difference in temperature distributions on the central part and a surrounding part of the external circumference of a container small. CONSTITUTION:The titled heat accumulator is constituted with a container 4 obtained by connecting a plurality of pieces of small bags 3 containing a latent heat accumulating material 1 and a supercooling-prevention material 2 in all directions with each other, a heater 5 fixed to the small bag and a heat insulating material 6. A blank small bag 12 which is not filled with the heat accumulating material 1 and, moreover, not fitted with even the heater 5 is provided on the central part of the container 4. As the blank small bag 12 is neither heated by the heater 5 nor used for containment of the latent heat accumulator 1, the bag 12 becomes a radiating surface, the temperature is not raised and a temperature distribution range is made small. With this construction, as the small bag whose temperature is at the highest is covered partly with the heat insulating material, the temperature of the small bag becomes less than that of heat resisting life of the supercooling-prevention material 2 even if the temperature is raised, and generation of a supercooling phenomenon is prevented without spoiling a function of the supercooling prevention material.

Title: Surface washing of sintered parts
Inventor: FUJIWARA KATSUYA
IPC: B08B3/08
Filed: 1995-02-07
Abstract: PURPOSE: To prevent the sticking by residual oil and to suppress the adhesion of shot balls and powder by washing and drying sintered parts after a sizing treatment at a specific temp. at the time of washing the sintered parts by using a hydrocarbon based detergent. CONSTITUTION: The sintered parts are subjected to immersion washing with the hydrocarbon based detergent kept at over 30 deg.C and below 70 deg.C and are then dried at temp. slightly lower than the detergent temp., i.e., over 30 deg.C and below 60 deg.C. The detergent temp. is set at 60±3 deg.C and the drying temp. at 55±3 deg.C if the lubricating oil for sizing is rapeseed oil. The oil impregnated in the inner circular opening parts of the sintered parts after sizing is oozed by thermal expansion when the parts are immersed into the detergent kept at about 60 deg.C and, therefore, the washing effect is enhanced. The oozing is stopped by a slight fall of the temp. and the effect of pulling back acts on the residual oil at the time of drying, by which the sticking after the drying is prevented.  The oozing continues even at the time of drying if the washing temp. is too high and, therefore, the upper limit temp. is confined to 70 deg.C.
