Title: Rotary head device
Inventor: KITAKATA MASAHIKO
IPC: G11B5/52
Filed: 1989-03-31
Abstract: PURPOSE:To eliminate the adverse influence to a rotary upper drum attached with a magnetic head in a compact, light-weight and simple constitution by using a rotary shaft connected directly to the rotary upper drum, a fixing member which attaches the rotor of a motor to the rotary shaft, and a tacky member which is put between the rotor and the fixing member. CONSTITUTION:A rotary shaft 13 is connected directly to a rotary upper drum 11 attached with a magnetic head. A fixing member 15 is used to attach a rotor 14 to the shaft 13 and a tacky member 16 is put between the member 15 and the rotor 14. The is, the member 16 is used to prevent such an inconvenient case where the shaft 13 connecting directly the drum 11 and the rotor 14 produces the twist resonance and gives the adverse influence to the drum 11. In this case, the elasticity and the cohesive power of the member 16 prevent effectively the twist resonance and surely attenuate the twist resonance in a short time. As a result, the attachment of a flywheel, etc., is omitted to attain a compact, light-weight and simple constitution of a rotary head device together with an inexpensive price.

Title: Fermented butter and production thereof
Inventor: KANEKO TSUTOMU
IPC: A23C9/12
Filed: 1986-04-14
Abstract: PURPOSE:To produce delicious fermented buffer suiting the taste of Japanese, by adding fermented milk and salt to granular butter produced by churning cream and kneading the mixture under pressure. CONSTITUTION:Fermented milk is prepared by using several kinds of lactobacilli such as Streptococcus diacetilactis, etc., which is a lactic coccus capable of producing flavor substance in addition to a lactobacillus such as Lactobacillus bulgaricus for imparting flavor to the product. The use of the above bacterial strains is essential in the present process. The strains are used separately or as a mixture and cultured in a general lactobacillus medium to obtain fermented milk corresponding to each strain. Both milks are adjusted so as to give a product having an acetaldehyde content of 0.5-2.5ppm and a diacetyl content of 0.05-0.5ppm and are mixed with each other. The amount of fermented milk to be added to the granular butter after the completion of churning is smaller the better in view of preservability of the product and its upper limit is about 1-5%. Since unsterilized fermented milk is used as a raw material, it is preferable to add about 10-20% salt based on the fermented milk to suppress the activity of lipase and proteinase.
