Title: Defroster in refrigeration apparatus
Inventor: DOMYO NOBUO
IPC: F24F11/02
Filed: 1989-05-18
Abstract: PURPOSE:To start and stop the defrosting opportunely so as to improve the defrosting performance by controlling the number of revolutions of the motor of a blower for an evaporator through control of the phase at which a voltage is impressed and by direct detection of the frost formed on the evaporator according to the relation between the phase angle and the number of revolutions. CONSTITUTION:The number of revolutions N of the motor M of a blower 4a is maintained at a set number of revolutions. Whereas, when an evaporator 4 is free of frost, the phase angle phi at which a voltage is impressed is a set phase angle phi1, the phase angle phi decreases with formation of frost on the evaporator 4 and below the lowest standard phi2 when the formation of frost reaches a specified amount; timed opportunely to this condition, a defrosting means 17 is actuated and starts defrosting the evaporator 4, the phase angle phithen recovers the normal value phi1. By stopping the defrosting immediately after the frost has been completely cleared, the defrosting can be ended opportunely.

Title: Laser oscillation tube
Inventor: KOTANI KOICHI
IPC: H01S3/03
Filed: 1985-06-14
Abstract: PURPOSE:To increase the output of a laser or to reduce the size of a laser oscillation tube by mounting, containing or connecting a heat pipe partly at, in or with the oscillation tube to cool a discharge electrode by the pipe. CONSTITUTION:A heat pipe 4 is buried in a discharge electrode 2 in an oscillation tube vessel 1. The electrode 2 becomes high temperature by a pulse-shaped high voltage discharge in the tube 1. The high temperature heat is externally removed by fins 3, and the mounting portion of the fins 3 also becomes a high voltage connector. The heat applied to the surface of the electrode 2 is uniformly transported axially by the pipe 4, and then transmitted by the fins to the exterior of the vessel 1. Thus, it can prevent the electrode 2 from thermally deforming to efficiently remove the heat and to reduce the size of the tube.

Title: Cataplasm for medical use
Inventor: OKA TAKAYUKI
IPC: A61K9/70
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To prepare a cataplasm for medical use free from a crosslinking agent, extremely improved in cohesive force of the adhesive layer and causing no skin irritation attributable to the absorption of a remaining part of the crosslinking site of an organic peroxide from the skin even in the case where the part remains in an unreacted state. SOLUTION: An adhesive layer mainly consisting of a (meth)acrylic acid alkyl ester (co)polymer is formed on one side of a supporting body, and the coated supporting body is heated at 90-120 deg.C. The (meth)acrylic acid alkyl ester (co)polymer is produced by (co)polymerizing in the presence of an organic peroxide [e.g. 1,1-bis(t-butylperoxy)-2methylcyclohexanel containing two or more peroxide sites (00-bond) each having a different decomposition temperature in a molecule as a polymerization initiator. The peroxide sites decompose very slowly near room temperature, and accordingly, the thickening of the viscosity of a coating solution, the variation with age regarding the adhesivity properties of the product, etc., hardly occur. Further, the cohesive force can be efficiently increased after application even in the system in which a liquid component is compounded.  Thus, the objective product having low irritation can be produced.
