IPC: G11B5/09
Filed: 1987-04-15
Abstract: PURPOSE:To prevent the overshoot of a flyback voltage waveform and to speed up the direction switching of a current by setting the inverted timing of a complementary write data signal which is impressed on the base terminal of a transistor connected between read/write terminals in a driving terminal and a constant-current power through an n-staged gate delay circuit. CONSTITUTION:For bridge-driving a magnetic head at the time of write action, couples of first and second transistors Q1-Q4 connected with a couple of read/ write terminals and the n-staged (n>=1) gate delay circuit 20 connected with the base terminal of a couple of the second transistors Q3 and Q4 are given. The inversion of the complementary write data signal which is impressed on the transistors Q1 and Q2 connected between a supply voltage and the read/write terminals and that of the complementary write data signal which is impressed on the transistors Q3 and Q4 connected between the read/write terminals and the constant-current powers can be obtained in a constant timing difference, and the overshoot of the flyback voltage waveforms in both terminals of the magnetic head is prevented, whereby the direction switching of the current is speeded up.

Title: Production of flavored soup stock
Inventor: TEI HO
IPC: A23L27/21
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a flavored soup stock by which an essence rich in both fragrance and a tasty ingredient can be extracted in high yield with good operating efficiency. SOLUTION: A coarsely crushed fushi (smoked and dried fish meat) is filled in a column and water or an alcohol solution is passed therethrough to extract an essence. A proteolytic enzyme solution is further passed through the extraction residue using the same column to extract the essence. The essence good in flavor at a high concentration is obtained by extraction at the first time; however, the extracted essence obtained by the extraction at the second time can be mixed with the essence obtained at the first time to thereby improve the Umami and simultaneously raise the yield.

Title: Production of friction material
Inventor: YAMAMOTO YASUNOBU
IPC: F16D69/02
Filed: 1979-07-17
Abstract: PURPOSE:To obtain a pulp-based friction material having excellent durability, by carrying out the heat-treatment in at least three different heating atmospheres, in the production of a pulp-based friction material. CONSTITUTION:In the production of a pulp-based friction material using, as a binder, a thermosetting resin such as a phenol resin, the heat-treatment of the friction material is carried out in at least three heating atmospheres each having a different temperature range. As compared with the conventional heat-treatment processes in which heat-treatment is conducted each once (twice in total) before and after a pressure/heat molding step, the present process requires more heating steps. Use of too many heating steps markedly increases the treating time and equipment cost. This results in high cost of production. Accordingly, use of 3-7 steps is total, each having a different temperature range, before and after the pressure/heat molding step is preferred.
