Title: Method of controlling transition of head
Inventor: KUSUMOTO TATSUHARU
IPC: G11B21/08
Filed: 1994-07-14
Abstract: PURPOSE:To equalize a seek time of a head to a target cylinder regardless of the moving direction of the head. CONSTITUTION:A target value filter 21 in a microprocessor 2 selects an optimum lamp value corresponding to the direction where the head 8 approaches to the target cylinder among the lamp values corresponding to the number of cylinders from a present cylinder where the head 8 is placed to the target cylinder to output it to a position error detection device 23. Thus, since a control variable outputted from a stabilization compensator 22 becomes one using the lamp value different according to the moving direction of the head, the control variable so that the influence by external force different according to the moving direction of the head is equalized is obtained. Since a driver 5 drives a VCM 6 so that the control variable becomes zero, and places the head 8 to the target cylinder, the influence by external force different according to the moving direction of the head is equalized, and the seek time is equalized.

Title: Engine control device
Inventor: IMATAKE NOBUO
IPC: F02D41/02
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To quickly elevate a catalyst temperature while eliminating the complication of an engine structure. SOLUTION: A fuel is injected into a combustion chamber CC even in an expansion stroke when the temperature of the combustion chamber CC is a prescribed value or less. Since a fuel is injected again after explosion of a fuel injected before the expansion strokee-during a suction stroke or a compression stroke), combustion is maintained for a long time. Since an exhaust gas of high temperature is discharged toward a catalyst 16, the temperature of the catalyst 16 is quickly elevated.

IPC: F24J2/40
Filed: 1979-12-14
Abstract: PURPOSE: To prevent damage, etc. due to freezing during the coldest season by automatically recovering all hot water into a hot water storage tank simultaneous with the stopping of a line pump by means of a temperature differential temperature adjustment device and emptying equipment of a heat collector panel system.  
     CONSTITUTION: If the temperature of water inside heat collector panels 1, 1 showed a significant decrease, compared to the temperature of water inside a hot water storage tank, following a temperature drop during night, etc. a line pump 2 stops. At that time, all water in the heat collector panels 1, 1, supply duct 3 and intake duct 4 falls into and is collected by the hot water storage tank 5 by a spontaneous water head between the heat collector panel and the hot water storage tank 5, as an air vent 6 is exposed to the atmosphere. The discharge end of a water intake  pipe 4 is open into the upper space of the hot water storage tank 5, so that it always maintains an atmospheric pressure and sucks an air from a suction vent valve 10 following a drop of the hot water level in the heat collector panels 1, 1. Thus the interior of the heat collector panel is equal to an atmospheric pressure, discharging an extra air in the hot water storage tank 5 through an air vent and also dropping/ recovering a hot water located upward.

IPC: A61M25/00
Filed: 1990-06-21
Abstract: PURPOSE: To prevent the humor safely and effectively from flowing back into a set catheter by leaking out an aqueous solution to absorb moisture via hydrophilic polyetherurethane(HPEU) to discharge out antithrombogen agent and simultaneously to increase the diameter to seal the internal wall of the catheter. CONSTITUTION: This covered embolus including a rod coated with HPEU, upon a contact with an aqueous solution, absorb moisture to increase its diameter. Inserting this embolus into a catheter left in a human body expands the hydrophilic polymer coat to get a contact with the inner cavity wall of the catheter to form a seal. Simultaneously, a complete of sodium heparin and heparin which is bulk-spread into the HPEU, is discharged out during a period of using the embolus to bring an antithrombogen action. Although the seal is adhered well enough to prevent the humor from flowing back into the catheter, the embolus is easily released from the catheter. This can prevent the blood and any other humor safety and effectively from flowing back.
