Patent JP-H0460560-A (JP)
Title: Image forming device
Inventor: MATSUDA ITARU
IPC: G03G15/043
Filed: 1990-06-29
Abstract: PURPOSE:To cancel offset quantity without calibrating a potential sensor by adjusting the quantity of exposed light so that difference between electrostatic charged potential before exposure and surface potential after the exposure is made constant. CONSTITUTION:The electrostatic charged potential VO on the surface of a photosensitive body before the exposure and the potential VL of a bright part after the exposure are respectively read by the potential sensor and the difference VA between them is made constant. Since offset, that means, the deviation of a true value caused by the attachment of toner actually exists, the difference between them considering the offset becomes VB. However, since the offset quantity of VO and VL are the same, VB = VA is attained. Therefore, it is good that VB is made constant. In such a way, the electrostatic charged potential before the exposure and the surface potential after the exposure are measured by the potential sensor and the quantity of the exposed light is controlled so that the value of the difference between them becomes a prescribed value which is previously fixed. Thus, the offset quantity is cancelled without calibrating the potential sensor.

Title: Cap for wide mouthed container
Inventor: HIDAKA TOMOYUKI
IPC: B65D47/08
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent elastic pieces of a hinge mechanism from twisting, and disperse the distribution of the generated stress by a method wherein the hinge mechanism is constituted of a hinge main body and a pair of elastic pieces being arranged on both sides of the hinge main body, and the elastic piece is formed into a structure wherein the elastic piece becomes an approx. arc shape under a lid open state at 180 deg., and the elastic piece may have an equal thickness extending to the total length. SOLUTION: Respective elastic pieces 34 of a hinge mechanism 16 are bonded along the outer peripheral surfaces of a cap skirt 12 and an overcap 14. The thickness of the elastic piece is made equal, extending to the total length. Since the stress of the elastic piece becomes a minimum under a state wherein a lid is opened at 180 deg., and when passing a change point from the lid open state, and the overcap 14 is rocked further, a tensile force is applied to the direction becoming a lid close state. On the contrary, in the case starting from the lid close state, the overcap 14 is rocked to the lid open state and is stabilized under that state. Thus, the end part of the elastic piece 34 moves in parallel with a reference plane which passes an intermediate point of a hinge main body 32, and for this reason, almost no twist is generated on the elastic pieces 34. Also, since the thickness of the elastic piece 34 is equal, extending to the total length, a stress concentration to the bonded end part, is dispersed.

Title: Decompression device for engine
Inventor: HIRATA MAKIZOU
IPC: F01L13/08
Filed: 1982-09-28
Abstract: PURPOSE:To facilitate the starting of an engine by operating a diaphragm value by a pump pressure at a fixed number of revolutions of an engine for controlling a cylinder pressure. CONSTITUTION:Over a fixed number of revolutions of an engine, a water pump 22 is rotated at a high speed, and a high pressure is introduced into a pressure chamber 20 through a pipe 21 to push a diaphragm 16. Consequently, a valve 2 is seated on a valve seat 11 against the elasticity of a spring 15 and the compressed gas in a combustion chamber 6, and a decompression hole 3 is closed. During the stoppage of the engine, or under a fixed number of revolutions, the pressure in the pressure chamber 20 is low, and the valve 2 is separated from the valve seat 11 by the elasticity of the spring 15 to open the decompression hole 3. While the decompression hole 3 is kept opened, a part of gas during the rise of a piston is leaked to an exhaust port 5 through a decompression hole 3 to lower the pressure of the compressed gas, and the engine can be started by a small torque. This construction permits to start engine easily, and stabilize the driving state during idling.
