Title: Intermittent rotary device
Inventor: KATO FUMIO
IPC: F16H35/00
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To convert a rotating motion of a motor into an intermittent rotating motion through a mechanical structure by a method wherein there are provided a first gear and a second gear cooperatively related to an input shaft of a motor, a third gear rotated in the same direction as that of the first gear through a cooperating means, a fourth gear engaged with the second gear and a one-way clutch. SOLUTION: As an input shaft 4 is rotated in a direction A by a driving shaft 2 of a motor 1, a rotation of a first gear 7 in the same direction through a one-way clutch 5 causes a third gear 25 to be rotated in a direction B through an idle gear 19 and also a rotation of a second gear 14 causes a fourth gear 37 engaged with the second gear to be rotated in a direction C. As the fourth gear 37 is rotated in a reverse direction, the second gear 14 is rotated in a reverse direction opposite to the direction A. Opposite rotation of the third gear 25 causes the first gear 7 to be rotated also in a reverse direction and further causes the input shaft 4 and the driving shaft 2 to be rotated in a reverse direction through the one-way clutch 5.  In this case, since the second gear 14 is rotated in a reverse direction at a high speed, a winding fastening force is generated at a first coil spring 11 to cause the input shaft 4 and the driving shaft 2 to be rotted in a reverse direction at a further high speed.

Title: Method and device for buffer memory access
Inventor: MATSUNO SUMIKAZU
IPC: G06F3/153
Filed: 1989-03-07
Abstract: PURPOSE:To shorten the cycle time of a memory access by allocating in advance plural pieces of memory devices for constituting a buffer memory to plural lines being different from each other, respectively, and executing an access to the memory device by a specific method. CONSTITUTION:Plural pieces of memory devices for constituting a buffer memory are allocated in advance to plural lines being different from each other, respectively. In this state, in the case of executing continuously an access to the memory device allocated to the same line, the access is executed, based on a line address which is set once and a column address which is varied successively, and after the line address is set, only the column address is varied. Also, in the case of executing the access to the memory device in the direction vertical to this access direction, the access to the memory device allocated to the line concerned is executed, based on a line address which is set as a difference value successively and a desired column address. In such a way, the cycle time of a memory access can be shortened.

Abstract: PURPOSE:To certainly decide and confirm the sticking location of the title sheet by covering the applying location of a pressure-sensitive bonding agent with a colorless, transparent silicone release film. CONSTITUTION:After applying and drying a colorless, transparent pressure- sensitive bonding agent liquid on the releasing surface, namely, on the bonding surface of a piece of film or printing paper, the silicone-film forming surface of a piece of silicone releasing film, which is formed by forming a silicone film on one surface of a polyester resin base, is put on and joined to the bonding agent applying surface. Then the sheet thus formed is placed on the sticking location of a map, etc., and the top section of the sheet is fixed to the map, etc., after confirming the location by looking through the sheet. Then, after the location is again confirmed by again inverting the map in such state, the sheet is strongly rubbed after the silicone releasing film of a cut section is removed. Therefore, the sticking part can be decided accurately and no rumple occurs in the map, etc.

Title: Three phase on-load tap changing transformer
Inventor: SOKAI KATSUJI
IPC: H01F29/04
Filed: 1985-03-20
Abstract: PURPOSE:To double changing capacity by forming each single phase coil with two parallelly diverted shunt coils to obtain a total of six shunt coils, and practicing tap change of three coils with one of two OLTCs and that of the remaining three coils with another OLTC. CONSTITUTION:The first OLTC 21 uses the tap coils, 7a, 9a, 9b, which correspond to those for three phases, with the first terminal 1 corresponding to a neutral point, similarly to the second OLTC 22. That is to say, the first and the second OLTCs 21, 22 use completely the function of OLTC constituted as used at the neutral point of each ordinary three-phase star rectifier connection. Thus letting the changing capacity for single phase equal to one unit, one OLTC has three units of changing capacity for three phases and two OLTCs have six units.

Filed: 1980-04-25
Abstract: PURPOSE:To prevent the leave of a signal charge and to improve transfer efficiency and the resolving power of picture quality by expanding the channel width at the location changing the transfer direction of the signal charge along the transfer direction. CONSTITUTION:In a charge transfer device arranged a read out register 19, a bottom gate 20, and gate electrodes 21a, 21b, channels 22a, 22b are formed on the surface of a semiconductor substrate or around the surface to transfer a signal charge from storage sections 21a, 21b to the read out section 19. The channels 22a, 22b are formed to expand the channel width along the transfer direction of the signal charge at the last stage of the transfer electrode section 20. In this way, the electric potential inclines to the transfer direction even when the length of the electrode at the  final stage is long. Therefore, the leave of transfer will not exist and transfer efficiency will be improved.
