Title: Motor-driven power steering device of shock absorption type
Inventor: IMAGAKI SUSUMU
IPC: B60R21/05
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a motor-driven power steering device of shock absorption type capable of being assembled easily and assuring good economy. SOLUTION: A torque sensor 20 to sense the transmitted torque through a steering shaft 5 in a position farther from a steering wheel than a column 2 is covered with a sensor housing 21 provided separately from the column 2, and a motor 32 is installed at the sensor housing 21 for generating a steering auxiliary force in compliance with the sensed torque. At least part of a member supported on the column side of the steering shaft 5 is displaced by the action of a shock. A coupling member 51 to couple the sensor housing 21 to the column 2 is plastically deformed by the displacement of the column 2 due to the action of the shock.  It is arranged so that the coupling works of member 5b supported on the column side of the steering shaft 5 with a member 5c supported on the sensor housing side can be conducted externally in the radial direction of the steering shaft 5, and therefore, part of the surrounding region of the coupling part is left open.

Title: Special electrode for machining inner surface deformed hole
Inventor: TAKAGIWA KOICHI
IPC: B23H3/04
Filed: 1992-12-16
Abstract: PURPOSE:To enable machining of larger height difference in the inner wall of a deformed hole to be drilled by a special electrode which is used for electro-chemically machining various inner surface deformed holes such as grooved holes for tube expanding in heat exchanger tube plate, cooling holes in gas turbine blade, etc. CONSTITUTION:In an electrode for electro-chemical machining 1, the form and cross-section dimensions of its top end 1' are swelled and exposed so that they are identical to those of a coating section 2. A high-pressure machining fluid 4 passes through the inner center section of the electrode 1, flows from the top end 1' of the electrode in the outward arrow direction, and rises through a clearance between the hole wall of a work base metal and the electrode to be exhausted to the outside of the hole while the electro-chemical machining is made by electric discharge between the top end of the electrode and the work base metal 3. Also, because the top end of the electrode is exposed out of the coated section 2, and the form and cross-section dimensions of the top end 1' are made identical to those of the coating section 2 to form a special electrode, a distance L between the work base metal 3 and the top end 1' of the electrode is reduced to increase the electro-chemical performance due to discharge from the electrode.

Title: Tape cassette
Inventor: OTA TAKASHI
IPC: G11B23/087
Filed: 1991-12-26
Abstract: PURPOSE:To protect from damage by making the gap between an upper reel flange and the peripheral rib of the frange narrower than the gap of a lower reel and prevent the upper reel coming into contact with the peripheral rib at the time of shock. CONSTITUTION:A reel housing part 4a surrounded with a rib 3a having a center (a) is formed on the upper half 1 and the upper reel flange 6a at the one side of a hub is housed. The rib 3a, a reel housing part 4b and a lower reel flange 6b are housed in a lower half 2. A comb-shaped part for reel lock 7 is formed on the outer peripheracy of the flange 6b. At this time, the gap between the frange 6b and the rib 3a is made narrower than the gap between the flange 6b and the rib 3b. Thus, since a reel bearing supports mobably in a radial direction when the shock due to falling is applied, the flange 6a abuts on the rib 3a and stops, then the flange 6b with the wider gap is not in contact with the rub 3b. Consequently, the shock is not applied compeletely.

IPC: H02P23/07
Filed: 1992-12-25
Abstract: PURPOSE:To prevent the occurrence of hunting, etc., by storing the time until a set frequency is reached after acceleration or deceleration starting time and the frequency difference between a set frequency and the frequency at the acceleration or deceleration starting time. CONSTITUTION:The inclination S1 of an output frequency is calculated based on the output frequency difference of an inverter 2 at the preceding accelerating or decelerating time and the time required for the acceleration or deceleration and the current acceleration or deceleration is performed in accordance with the inclination S1. When the output T of a torque computing element 7 exceeds a preset limit value (on the driving side) during the acceleration, the acceleration is stopped and, when the torque T becomes equal to or smaller than the limit value, the acceleration is again started in accordance with the inclination S1. Thus a step-like acceleration curve shown by the solid line in the Figure is obtained and the time tA, actually required for the acceleration and an output frequency difference (against a set frequency fs) are stored in an appropriate storing element so as to find the inclination S1 of the next time.
