Inventor: SENDA JUN
IPC: H02M3/28
Filed: 1987-07-15
Abstract: PURPOSE:To lower reverse voltage to a switch element, by applying input voltage and voltage corresponding to a duty factor, to a capacitor, with a control voltage generating means. CONSTITUTION:So far as a DC-DC converter is concerned, the primary winding n1 of a series-connected transformer T, a transistor(Tr) Q3, and a capacitor C3 in a control voltage generating means 3 are connected to a DC power source 4, and the secondary winding n2 of the transformer T is connected to a load RL via a rectifying and smoothing section 2. Besides, when the Tr Q3 is ON/ OFF-worked according to control signal, then by said control voltage generating means 3, a Tr Q2 is used and voltage according to input voltage Vin and a duty factor is applied to the capacitor C3. Then, the voltage applied to the primary winding n1 serves as a difference component between the input voltage Vin and the voltage of the capacitor C3, and voltage applied to a Tr Q1 and a diode turns constant regardless of the duty factor, to reduce applied voltage.

Title: Ship with off center shaft
Inventor: MATSUMOTO NORIHIRO
IPC: B63H20/00
Filed: 1986-07-30
Abstract: PURPOSE:To increase the propelling efficiency of a propeller by slightly offsetting a propeller shaft from a hull center line while maintaining the hull form of nearly right-left symmetrical ship form and contrarily utilizing the water flow of a longitudinal eddy. CONSTITUTION:The form of ship is a right-left symmetrical ship form which is symmetrically formed with a hull center line 2 as a reference, and a propeller shaft 3 is slightly offset from the hull center line 2 and only the part projecting out of the hull is unsymmetrical. A propeller always receives the flow of water in the opposite direction to its rotating direction, thereby, obtaining the same effect as that the rotating speed of the propeller is increased. Thus, by slightly offsetting the propeller shaft 3 from the hull center line 2 while maintaining the hull form of nearly right-left symmetrical ship form, the propelling efficiency of the propeller can be greatly increased by contrarily utilizing a longitudinal eddy which used to be the cause of lowering the propelling efficiency.

Title: Anti-inflammatory analgesic ointment
Inventor: KOBAYASHI SHINKICHI
IPC: A61K31/40
Filed: 1985-08-13
Abstract: PURPOSE:To obtain an anti-inflammatory analgesic ointment having low stimulation to the skin compared with conventional ointment and high absorbability, by compounding indomethacin with a basic amino acid as a dissolution agent, a lactic acid ester as an absorbefacient, and further a gelling agent and a thickener. CONSTITUTION:The objective agent can be produced by compounding (A) 0.5-1.5wt% indomethacin, (B) a medium composed of 0.3-10wt% basic amino acid (e.g. lysine, arginine, etc.), 10-60wt% lower alcohol and 20-70wt% water, (C) 0.2-5wt% gelling agent and/or thickener (e.g. carrageenan, CMC, etc.) and (D) 0.2-10wt% lactic acid ester. The carbon number of the alcohol component of the lactic acid ester is preferably 12-18. Since the agent contains a basic amino acid in place of glycol as a dissolution agent, it has weak stimulation to the skin and is free from stickiness. The use of a lactic acid ester as an absorbefacient improves the absorbability of the agent. It can be stored stably for a long period.

Patent JP-H0924432-A (JP)
Title: Composite part and production therefor
Inventor: YAMAZAKI MASAAKI
IPC: B21D53/00
Filed: 1995-07-14
Abstract: PROBLEM TO BE SOLVED: To generate no deformation and to machine in a short time by fixing with pressing another member onto a member having a hole in a sheet being less than a specific thickness. SOLUTION: A hole except a circular shape is formed on a plate like member 1 being less than 1.5mm thickness. After another member 2 is fixed with pressing on the hole, the plate like member 1 is machined in a prescribed shape, and it is made as a camera shutter part. The camera shutter part that the weight is lightened and the strength of requiring part is kept surely is obtained. Because an attaching hole of a reinforcing member 2 is made in an ellipse shape or a square shape except the circular shape, after fixing, the rotating displacement of the plate like member 1 and the reinforcing member 2 is not generated. After the reinforcing member 2 is fixed on the plate like member 1, because the shaft hole can be punched together with the relative other part, the positional precision of the relative holes can be obtained easily.
