Title: Driving force distributing device
Inventor: ASANO HIROAKI
IPC: F16H48/38
Filed: 1990-07-20
Abstract: PURPOSE:To eliminate the tight corner braking phenomenon at the time of turning traveling by generating a normal directional differential between an outer wheel side output shaft, of which turning locus is large, and a rotary housing and a reverse directional differential between an inner wheel side output shaft, of which turning locus is small, and the rotary housing. CONSTITUTION:A rotary housing 21 of a driving force distributing device 16 is rotated by the torque from an engine through a driving shaft 14, a driving gear 26 and a ring gear 25. At the time of turning traveling, since a difference is generated in the rotating speed of a pair of output shafts 23, 24 with a difference of the turning locus of a right and a left wheels, a differential is generated between the rotary housing 21 and the output shafts 23, 24. Namely, for example, the pressure generated in one space 33 of a left wheel side is lower than the pressure generated in the other space 34 because of forms of each blade 35, 36. The pressure working to a piston 27 is therefore low, and the pushing force never becomes larger than the elastic force of a compression spring 32, and a clutch means 29 is not displaced. As a result, the transfer torque against the differential rotation is reduced to prevent the tight corner braking phenomenon.

Title: Fluid injection valve
Inventor: NAKAO YORITO
IPC: F16K31/70
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To improve the responsiveness of a fluid injection valve without enlarging it. SOLUTION: A fluid injection valve is provided with a valve element 3 and an actuator 4, and when the actuator 4 drives the valve element 3 to open an injection port 2, supplied fluids are injected.

Abstract: PURPOSE:To manage the quantity of copies to be used for each user without use of a physical management tool by storing in advance plural passwords and a count upper limit for each password and collating the password with an inputted password. CONSTITUTION:Upon the key entry of a user password, an operation panel 303 transmits it to a system controller 253. The controller 253 collates the entered password with a password stored in advance and returns the permission of the use by the user to the panel 303 when there is any coincident password in the memory. The panel 303 indicates the copying machine mode and the copying enable state is reached. When copying is executed, the controller 253 counts up a counter in response to the password and compares the upper limit stored corresponding to the password with the count and when the upper limit is reached, the copying is stopped and the result is displayed on the panel 303. Thus, the quantity of copies to be used by each user is managed and the management efficiency is improved.
