Title: Four-wheel drive vehicle equipped with automatic transmission
Inventor: KOBAYASHI TOSHIO
IPC: B60K17/346
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To increase the transmission efficiency of highest transmission stage by increasing by a center differential device a speed for a transmission stage having a highest transmission efficiency so as to obtain a highest transmission stage having a smallest transmission ratio. SOLUTION: In an automatic transmission 30, among transmission stages, a third speed for directly connecting an input shaft 14 with an output shaft 15 has a highest transmission efficiency. Thus, when a speed is further increased under the traveling condition of a fourth speed and a speed is shifted to a fifth speed as a highest transmission stage, the automatic transmission 30 is placed in the state of the third speed, the second sungear 53 of a center differential device 50 is simultaneously fixed by the engagement of a brake 63 for the fifth speed, and a carrier 55 is increasingly rotated. Then, the motive power of the third speed of the automatic transmission 30 is transmitted to front wheels after the carrier 55 by greatly increasing the speed of the center differential gear 50, and a speed is shifted to the fifth speed.  Thus, since the third speed having the highest transmission efficiency is increased, a transmission efficiency is increased when a highest transmission stage is obtained.

IPC: H03J7/28
Filed: 1994-03-14
Abstract: PURPOSE:To select a desired genre by an easy operation and to preset its frequency by providing a retrieval means that sequentially fetches broadcasting station data having type information from a storage section based on type selection information. CONSTITUTION:When a control section 15 detects it that a category key of an input section 17 is being depressed for a prescribed time, a file of a storage section 11 is sought and a record having a relevant genre code is read sequentially to write the category code and the broadcasting frequency to a storage section 12.

Title: Actuation timing controller of copying machine
Inventor: TABEI HITOSHI
IPC: G03G21/14
Filed: 1982-04-26
Abstract: PURPOSE:To enhance reliability, by generating a detection reference signal for detecting the stop position of a photoreceptor at the time of manual drive, and reducing the number of sensors, e.g., photosensors used to one. CONSTITUTION:An actuation timing is controlled with one photosensor 4. When a movable mark 7a attached to a disc 3 is allowed to coincide with a fixed signal 7b attached to a stationary system (e.g., a part of a housing in a copying machine), a notch 3 for the stop position of a disc 3 comes to a position detectable by a photosensor 4. When a pulse signal 4a is fed from the photosensor 4 to a microcomputer (not illustrated) installed in the copying machine, the stop position is checked by an on-check signal 8 and detected. When the mark 7a of a photosensitive drum 2 is allowed to coincide with the mark 7b in the manual operation at the time of maintenance, a reference signal is generated for example, by operation of a button, or a limit switch, or the like. Then, the disc 3 is manually driven, the first decay of the sensor signal 4a is detected after the output of the reference signal, and it is programmed that the (1) signal fed after that is processed as a clock signal, thus permitting according the start position of the drum 2 with the sequence at the time of maintenance.

However, a1=(a difference between a preadjustment dynamic injection amount and K2)Xtanalpha1, a2=(a difference between K1 and K1)X tanalpha2, alpha3=(a difference between K1 and a final target value)X tanalpha3, and according to this spring change amount, the spring force is changed, and in the case of not entering into the final target range, adjustment is made on and after a second time.

Abstract: PURPOSE:To contrive to protect the coil part of an AC adapter by fusing a temperature fuse surely at abnormal time by a method wherein pouring resin is filled up in the case of the AC adapter as to exclude the temperature fuse part. CONSTITUTION:Parts for rectification such as a transformer 14 formed by winding a coil 21 incorporated with a temperature fuse 13 around a core 20, diodes 15, 16, a capacitor 17, etc. are accommodated in the case 19 consisting of an insulator of an AC adapter.
