Title: Multi-channel thin film magnetic head
Inventor: KATO YOSHIAKI
IPC: G11B5/31
Filed: 1987-10-05
Abstract: PURPOSE:To obtain a thin film magnetic head with excellent production yield without deterioration in the S/N by etching simultaneously insulation layers existing in the region with an upper magnetic substance arranged thereupon through a gap layer and the region between the upper magnetic substances forming a multi-channel. CONSTITUTION:The region arranged with the upper magnetic substance 8 in the region forming a front gap 5a and insulation layers 2, 4 existing between the regions arranged with the upper magnetic substance 8 and with other upper magnetic substance are etched simultaneously. Since the insulation layer is etched over the entire face, a curved gap between the upper and lower magnetic layers or an effective reduction in the track width is avoided. Thus, the magnetic head without azimuth loss with excellent S/N is manufactured with good yield.

Title: Electrode for battery and its manufacture
Inventor: FUJII TOSHISHIGE
IPC: H01M4/13
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To provide an electrode for a battery with high adhesion between a current collector and an active material layer and low electrical resistance. SOLUTION: An adhesive layer 2a having a dot-like, stripe-like, or grid-like coating pattern is formed between a current collector 1 and an active material layer by spray or printing. While the coating area ratio of the adhesive layer 2a to the area of the active material holding surface of the current collector 1 is specified to be 30-80% to keep sufficient adhesion, electron exchange between the current collector 1 and the active material layer is conducted smoothly in the non-coated part, and the electrical resistance is kept low. By selecting a lithium ion absorbing/releasing material as the constituting material of the active material layer, a lithium secondary battery with high performance can be obtained.

Title: Manufacture of semiconductor device
Inventor: MATSUMOTO NAOYA
IPC: H01L21/306
Filed: 1990-09-20
Abstract: PURPOSE:To easily detect the end point of etching by forming a polysilicon film under a BPSG film. CONSTITUTION:A polysilicon film 4 is deposited on a silicon oxide film 3 that includes a trench 2. Further, a BPSG film 5 is deposited by low-pressure CVD to fill up the trench 2, and it is heated to reflow until a flat surface is obtained. The BPSG film 5 is etched, and then the polysilicon film 4 is etched. In this phase, the polysilicon film and the silicon oxide film are largely different in reflectivity, so a significant change of color is observed. As a result, it is easily recognized that the polysilicon film 3 has been removed and the underlying silicon oxide film has been exposed. Therefore, it is possible to automatically detect the end point of etching by using a laser reflection detector.
