Abstract: PROBLEM TO BE SOLVED: To prevent a deformation such as the warp of a bar state work generated during the production process of the work from occurring and to realize a magnetic head, which is highly precise and is of a low cost, by conducting a PH machining against the last tip section work train of a waffer shaped work by a grinding, conducting a ROW cutting machining against the train, that has completed the PH machining, and obtaining a PH machined bar sate work. SOLUTION: A waffer 10, which is to be machined, is fixed to a work table 9 by hot melt adhesive and the table 9 is fixed to a rotary table 8 with a vacuum chuck. The table 9 is one of the consumption members to be machined with the waffer 10. Then, a PH grinding is conducted for the waffer 10 by a cup grindstone 4 which is mounted on a PH grinding spindle 5. After the grinding, the waffer 10 is ROW cut machined into a bar state work by a cutting grindstone 6 mounted on a cutting spindle 7. Thus, the deterioration in precision caused by a deformation such as the warp of the bar state work during the PH machining is prevented and the quality and the yield of the products are improved by the highly precise machining.

Inventor: WYSER JOHANN
IPC: A41C3/14
Filed: 1994-02-02
Abstract: PURPOSE: To initialize the closure action of a venting valve by transmitting the impact force applied to a power pick up means by a liquid casting material to an axially displaceable valve closing means of a venting valve means, thereby absorbing and decreasing kinetic energy by the power pick up member.

Title: Coloring agent and aromatizing agent comprising extract derived from leaf of eucommia ulmoides
Inventor: YAMADAKI MOTOZUMI
IPC: A23L1/275
Filed: 1990-01-19
Abstract: PURPOSE:To obtain a pitch-black coloring agent or an aromatizing agent having a mellow aroma comprising an extract derived from the leaves of Eucommia ulmoides by treating a liquid prepared by extracting dry leaves of Eucommia ulmoides with hot water. CONSTITUTION:The leaves of Eucommia ulmoides picked before being shed are dried in air and water is added thereto to conduct extraction for, e.g. about 20min at 100 deg.C. The extraction residue is removed and washed with water several times in order to completely extract the ingredient. The extract is combined with the washings and passed through an adsorption column to allow the adsorbent to adsorb the ingredient contained in the solution, and a desorption solvent is passed through the column to desorb the ingredients from the adsorbent. An ion exchange resin can be used as the adsorbent. A dilute acid solution or a dilute alkali solution is used as the desorption solvent; a dilute alkali solution is desirable for obtaining a pitch-black extract, and a dilute acid solution is desirable for obtaining an aromatic extract. The eluate is concentrated. The extract thus obtained from the leaves of Eucommia ulmoides contains an ingredient having a mellow aroma and a pitch-black color characteristic of Eucommia ulmoides.
