Title: Preparation of positive electrode material for lithium battery
Inventor: HANABUSA KIYOSHI
IPC: H01M4/08
Filed: 1990-09-05
Abstract: PURPOSE:Not to be affected by the content of contamination components in raw materials by using atmospheric gas dampened by steam at the time of firing a mixture of manganese dioxide and at least one of LiOH, LiOH.H2O, and Li2O3. CONSTITUTION:MnO2 and at least one of LiOH, LiOH.H2O, and Li2CO3 are mixed in a mole ratio of Mn to Li of (8/2)-(5/5). Then, the mixture is fired in atmospheric gas dampened by steam. At that time, the steam converts contamination components (Li2CO3) in the LiOH.H2O raw material into hydroxide and cancels them. Consequently, without affected by the contamination components, a positive electrode material with stable quality is prepared by a simple apparatus.

Abstract: PURPOSE:To improve joining strength and reliability of the joining part of silicon carbide material by chemically treating the face to be joined of silicon carbide material and forming open pores a bonding agent to penetrate in and thereafter joining material to be joined. CONSTITUTION:The face to be joined of silicon carbide material obtained by a reaction sintering method is chemically treated by strong alkaline chemicals or strong acidic chemicals.

In such a way, the open pores having prescribed depth are formed on the face to be joined of silicon carbide material and a joining agent holdable in a fluidized state is allowed to penetrate into the open pores and thereafter material to be joined is joined to this joining face. The open pores having a complex shape are formed on the surface layer part of silicon carbide material by performing joining in the above method. The bonding agent or the material to be joined is introduced into the open pores and thereby both silicon carbide material and the material to be joined can be tightly joined by so-called anchoring action.

IPC: G11B7/24047
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To obtain an optical information recording medium of low noise, sufficiently high S/N and large capacity by forming a reflection layer having a region where the concn. of at least one among oxygen and nitrogen is high. SOLUTION: This optical information medium is produced by directly forming the Al reflection layer 2 on a substrate 1, sticking a protective plate 4 thereto and forming an adhesive layer 3. In such a case, the Al reflection layer 2 is formed by using gas formed by incorporating oxygen or nitrogen into gaseous argon or gaseous mixture composed of oxygen and nitrogen by a sputtering method using a high-frequency magnetron sputtering device. The optical information medium produced in such a manner is low in the noise and is high in the S/N. In addition, the line recording density thereof is made sufficiently high. The optical information recording medium having the large capacity is thus obtd. The reflection layer 2 consists of at least two layers of metallic layers.  The noise characteristic is further improved by forming an intermediate layer contg. the oxide or nitride between the respective metallic layers.

Title: Method and device for sealing semiconductor device with resin
Inventor: IWASE YOSHIHIRO
IPC: H01L21/56
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To prevent defectives due to the generation of voids through the fluid states of resins at the time of resin-sealing by the difference of the melting viscosity of the resins and defectives, due to the positional change of an element- loading section. SOLUTION: Cavities 2, 9 are formed in parallel in a direction along which gravity works, and a gate 4 for filling a resin is formed at the lowermost ends of the cavities 2, 9. Air vents 3, 10 for discharging air in the cavity 4 are formed at the uppermost ends of the cavities facing opposite to the gate 4. The position of a runner 5 is placed at a section lower than that the gate 4, and a pot 6 is installed at a place lower than the runner 5. As a result since the resin is fluidized in a opposite direction to the direction along which gravity works at all times by mounting components filled with the resin at an earlier rate at lower places in gravity, the resin can be filled uniformly by the left-right cavities, because the resin is fludized between the left-right cavities when fine filling difference is generated by the structure of a package by the left-right cavities.

Abstract: PURPOSE:To make a distal end as short as possible for preventing it from damages even if it is subjected to tensile variation due to bending by bending fixedly a printed substrate at the rear face of an optical system and disposing electric parts on the rear face side of the optical system. CONSTITUTION:A flexible substrate 9 is bent by a right angle at the operating side end of an image pickup element module 8 and the rear faces 8a, 7a of the module 8 and a jig 7 are bonded to each other through an adhesive agent 13. Electric parts 11 such as a path control and amplifier are attached on the bent part of the flexible substrate 9 and a signal line 10 for transmitting an electric signal to the operating side is connected to the flexible substrate 9 at a right angle thereto. Thus, the total length of the distal end 1 can be shortened and the radius of rotation can be shortened when the bent part is operatively bent so that photography in a narrow space becomes possible and a pain given to a patient can be reduced. Also, since the whole flexible substrate 9 is bonded to the image pickup element module 8 or jig 7, fatigue strength in bending is remarkably improved.

Filed: 1987-09-25
Abstract: PURPOSE:To aim at improvement or the like in reliability by comparing each integrated value of a cylinder internal pressure increment just before or after a compressive top dead point with each threshold value corresponding to the former, and stopping such control that sets the detected value of a cylinder internal pressure maximum crank angle position down to a feedback signal at the required time. CONSTITUTION:A means 3 detects a maximum crank angle position in engine cylinder internal pressure. And, a means 4 calculates a feedback value on the basis of a deviation between the detected value of the maximum crank angle position and the specified desired value. And a means 6 compensates fundamental ignition timing on the basis of the feedback value, and calculates output ignition timing. In these means, each cylinder internal pressure increment ranging from the specified crank angle position to a compressive top dead point as well as from this compressive top dead point to the specified crank angle position is integrated by each of means 7, 8. In addition, each integrated value is compared with each threshold value corresponding to these valves. When these integrated values all are smaller than these threshold valves, the compensation is stopped by a means 11.
