Title: Bending method for aluminum material
Inventor: YOKOYAMA MASAO
IPC: B21D7/08
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a die from being seized and gnawed by adjusting the surface roughness, the surface oxide layer of a work made of Al below a fixed value to execute bending. CONSTITUTION:When bending is executed to the work made of a long sized Al material, the surface of the work 10 is adjusted to a <=20mum surface roughness, Ra and the thickness of the surface oxide layer is adjusted below 30Angstrom . The work 10 is bent when the work 10 is advanced under the supply of lubricant as it is forced into a work communicating hole 9 of a movable gyro die 3 through a work communicating hole 4 of a fixed die 2, and a two-dimensional or three-dimensional bend is given by changing the direction and position of a gyro die 3. The surface roughness of the work 10 affects lubricating action by reducing the frictional force and also the thickness of the oxide film improves the lubricating function by improved retention of working oil to prevent the lubricant from being short.

Title: Anti skid control device
Inventor: ENOMOTO NAOYASU
IPC: B60T8/58
Filed: 1993-12-03
Abstract: PURPOSE:To perform optimum braking force control within a range in which the braked operation of a wheel can follow it by determining the relative changes of braking torque and tire torque. CONSTITUTION:Braking torque imparted to a wheel WL is detected using a braking torque detection means BS and tire torque generated by the friction force of the wheel WL against a road surface is detected using a tire torque detection means TS. These detection outputs are compared with each other using a relative change determining means RD so as to determine change in the braking torque relative to the tire torque. A hydraulic pressure controller AC is driven according to the determination result of the relative change determining means RD and change in the tire torque, to control brake fluid pressure that is supplied to a wheel cylinder WC. The difference or ratio of the braking torque to the tire torque is computed, for example, and the brake fluid pressure is controlled so that the difference decreases or that the ratio approximates 1.

Title: Image recording device
Inventor: KAMIMURA NORIFUMI
IPC: H04N5/225
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent the possibility that a photo opportunity is missed by making a time from a normal power consumption mode to a low power consumption mode different between when an liquid crystal finder is off and when it is on. SOLUTION: When a liquid crystal on-off switch 14 is set to liquid crystal finder-on, an MPU 11 starts time measurement after various operations are completed and starts a low power consumption mode when a 1st time passes. When the switch 14 is set to liquid crystal finder-off, it similarly starts a low power consumption mode when a 2nd time passes. That is, when the liquid crystal finder 6 is off, it takes a longer time to start the low power consumption mode, which reduces the possibility that time lag occurs in switching from a low power consumption mode to a normal power consumption mode and prevents a photo opportunity from missing.
