Patent JP-H05176600-A (JP)
Title: Controller for alternator
Inventor: KAKIZAKI SHIGEAKI
IPC: H02J7/16
Filed: 1991-12-25
Abstract: PURPOSE:To prevent the excess power generation of an alternator while obviat ing the sudden change of driving torque at a time when the load of the alterna tor suddenly changes when the alternator is controlled and battery voltage is controlled at target voltage. CONSTITUTION:The generated current of an alternator is feedback-controlled by using a proportional control gain iap and an integral control gain iai in response to a deviation DELTAV(Vreg-Vs) between the terminal voltage Vs of a car battery and target voltage Vreg. The integral control gain iai is set at a small value when a voltage deviation DELTAV takes a positive value and set at a large value when the deviation DELTAV takes a negative value in a step S5. Accordingly, when alternator load is increased, generated current is augmented gradually, thus preventing the sudden change of driving torque. When alternator load is diminished, generated currents are reduced quickly, and the excess power generation of the alternator can be inhibited, thus improving the reliability of the car battery.

Title: Document feeder
Inventor: KAMEYAMA TOSHIAKI
IPC: G03G15/00
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To eliminate convergence of a document due to conveying resistance in a document feeder with a conveyor belt for conveying the document upon holding it in a gap with a flat surface. SOLUTION: A conveyor belt 30 is made up of a rubber belt whose surface is not coated. Many crimps 31 and grooves 32 due to these crimps are formed on a surface at the side in contact with a document. A pattern 33 consisting of these crimps and grooves 31 and 32 is formed into symmetrical patterns being chevroned as bent once at the center after being angled in bordering a nearly central part in the traveling direction of the conveyor belt 30. Since it is made up of central symmetrical patterns, such individual component forces as trying to converge the conveyor belt 30 are offset with one another, so that convergence is not produced in the document being conveyed.

Title: Miniaturization of single-phase three-wire type auto-transformer
Inventor: MIZUNO TAKEHIRO
IPC: H01F29/02
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To miniaturize and lighten a single-phase three-wire system auto-transformer by a method wherein in the connection of the auto-transformer, the 0-phase terminal of a circuit is not connected with the auto-transformer. SOLUTION: In the case where an auto-transformer is installed on a single-phase three-wire type line, a change in the load balances in the auto-transformer must be taken into consideration. In the case where the R-phase and T-phase load balances are equal with each other, a current, which is made to flow in a shunt winding of the auto-transformer, may be through to be equivalent to that, which is made to flow in a shunt winding of an auto-transformer in the case of a single-phase two-wire type line. But, also in the case where the load balances are lost and are turned into a single load, it does not happen that a current, which is made to flow in the shunt wiring, may increase when this method is utilized.  That is a method for connecting a power supply, the auto-transformer and a load with each other by making the connection of (r) and (f) terminals of the power supply with R and T terminals of the auto-transformer, the connection of S and U terminals of the auto-transformer with (s) and (u) terminals of the load and the connection of a (n) terminal of the power supply with a 0-phase (o) terminal of the load. Moreover, an N terminal, which is a 0-phase terminal of the auto-transformer, is not connected even with where. By constituting the auto-transformer in such the method, it does not happy that an excessive current is made to flow through the auto-transformer, and the auto-transformer can be manufactured into a small size.

Title: Error correcting method for storage
Inventor: MIYATA MANABU
IPC: G06F11/10
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To effectively utilize a stand-by area and prolong the life of a storage itself by outputting data after correction as it is on condition that the number of defective bits included in read data is less than a set value when a correctable error is found in the read data or performing a substituting process using the stand-by area when the number of defective bits is larger than the set value. SOLUTION: Data is read out of a storage medium and stored in a buffer memory, and it is checked whether or not there is an error (S1-S3). For a correctable error, the data is corrected (S5) and then the number of defective bits is detected (S6). Then, the number of defective bits is compared with a previously set value (S7). An error occurring owing to external noise consists of nearly one bit and an error due to operation unstableness or a defect of the storage medium consists of >=2 bits in general. Therefore, when the number of defective bits is 1, the data is sent to a host as it is after correction (S9), but when >=2, the data is stored in the stand-by area and the substituting process for inhibiting the area so far from being used is performed.
