Title: Rectifier for open showcase
Inventor: NEGISHI KOUSABUROU
IPC: A47F3/04
Filed: 1977-10-14
Abstract: PURPOSE: To improve the performance of an open showcase, by providing a rectifier which is located at an air blow-off port of the showcase and has adjacent air  passages and by non-rectilinearly varying the length of the air passages in the front- to-rear direction of the showcase.  
     CONSTITUTION: An air passage 2 is defined on the inside surface of a heat-insulating casing 1. A cooler 3 and a blower 4 are provided in the air passage 2. Air sucked through a suction port 5 located in the lower part of the showcase is blown off through a blow-off port 6 of the upper part of the showcase and the rectifier 7 while the air is cooled. Thereby, an air curtain 8 is made between the inside and outside of the showcase. The rectifier 7 has numerous adjacent slender air passages of hexagonal cross section like a honey-comb. The upstream end face of the rectifier is so curved that the length of the air passages is non-rectilinearly varied in the front-to-rear direction of the showcase. As a result, the initial velocity v o  of the blown-off air is non-rectilinearly varied in the front-to-rear direction of the showcase. Thereby, the performance of the showcase is improved.

Title: Magnetic head
Inventor: HAMANA JIYUNJI
IPC: G11B5/105
Filed: 1982-07-16
Abstract: PURPOSE:To obtain a magnetic head prevented from tape squeaking, by incorporating a titanate type coupling agent in inorg. fine powder, mixing them with resin, and then, fixing a magnetic head core in a shield case core using a fixing agent obtd. by adding an org. lubricant to said mixture. CONSTITUTION:The titanate type coupling agent is attached to the surface of fine inorg. powder, such as SiO2 or Al2O3 by 0.1-7.0wt% of said powder by directly scattering the agent over said powder, or immersing said powder into a volatile solvent dissolving the agent, followed by evaporating the solvent or the like. This coated powder is mixed with a binder resin, and further, an org. lubricant is added to these mixture to prepare a fixing agent 3. When the half bodies 1, 1' of a magnetic head core have laminated structures, eatch layer is stuck to each other using this fixing agent 3, and the magnetic head element 1 is fixed in the shield case 2 using it, too. Accordingly, the org. lubricant has not been adsorbed to the inorg. fine powder, so saving an amt. of it to be added, and since the resin of the fixing agent is not softened, it is prevented that the surface in contact with a magnetic tape raised in friction resistance causes tape squeaking, and unsmooth tape traveling.

IPC: B01D53/77
Filed: 1981-08-07
Abstract: PURPOSE:To carry out deodorizing inexpensively in high efficiency, by a method wherein water is introduced into the packing bed of a particulate medium to which microorganism is adhered and a malodorous gas is diffused throughout said packing bed to dissolve and absorb malodorous components by water, besides carrying out oxidizing or reducing treatment by microorganism. CONSTITUTION:Replenishing water 15 such as waste water is introduced into an aeration tank 21 having a packing bed 14 comprising a particulate medium 13 such as sand or coke to which aerobic microorganism is adhered and a malodorous gas 11 is injected from a gas diffusing pipe 12. The gas raised through the packing bed 14 is exhausted from an exhaust port 17. A part of replenishing water 15 is discharged out of the tank as effluent water 19 and the remainder thereof is again flowed into the packing bed through a recirculation flow passage 20 and contacted with the malodorous gas 11 to remove malodorous components. When oxygen in the malodorous gas 11 is defficient to oxidative decomposing action of microorganism, an oxygen containing gas 18 is replenished. When anaerobic microorganism is used, a hermetically closed anaerobic biological treating tank blocked from the atmosphere is used in place of the aeration tank and a malodorous gas from which oxygen is removed beforehand is diffused.
