Filed: 1992-03-19
Abstract: PURPOSE:To increase the reliability and the degree of integration in a manufacture of a semiconductor integrated circuit device. CONSTITUTION:In the principal surface of the inactive region of a substrate, with an oxidation-resistant mask 5 as a mask, a groove 6 is formed, a PSG film 8 is formed, the surface of the groove 6 is oxidized, an insulation film for isolating elements is formed, and the oxidation-resistant mask 5 and the PSG film 8 are removed respectively.

IPC: E02D17/20
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To secure a topsoil-holding panel or the like without damaging the structure of a sloping frame and to prevent the temperature of the topsoil inside the sloping frame from rising.

Title: Magnetic disc device
Inventor: YOSHIZAWA TADASHI
IPC: G11B23/00
Filed: 1981-04-27
Abstract: PURPOSE:To prevent the vibration of a magnetic head and to block flowing of dust, etc. between discs, with such a simple means as a spacer is made of a sintered metal. CONSTITUTION:As a spacer chip between magnetic discs 10, a ring member 14 made of a sintered metal, rejecting dusts and passing through air is used. Since the sintered metal is porous, air can be passed through, but dusts and crack pieces which are greater than air particles, i.e., oxygen and nitrogen molecules can not pass through. Even with the presence of air flow between magnetic discs, since the air flow passes through a filter twice, a failure due to dust and crack pieces moving to the discs can not take place. The spacer is different from conventional spacers having no hole or notch but porosity. The rigidity of this sintered metal ring is sufficient and the distance between the discs 10 can be kept with high accuracy.

Title: Grinding of semiconductor substrate and semiconductor device and its manufacture
Inventor: WAI SHINICHI
IPC: H01L21/683
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To increase the throughput of a thickness reducing process, prevent the breakage, reduce the cost, and increase the accuracy of the finished thickness only by a grinding process by using a grinding stone whose grain diameter is within a specified range and processing at a specified rotating speed. SOLUTION: A grinding stone 32 supported by a finish grinding spindle 20 is a resin bonded grinding stone whose grain diameter is about 2-4 μm (about #4000). When N1 is a rotating speed of the grinding stone 32 and N2 is a rotating speed of a wafer 90, a grinding work is executed under the conditions that N2/N1 <= about 0.025-0.006. Under these conditions, a thickness reducing process of the wafer 90 can be done only by a grinding process, and with a high throughput. The breakage of the wafer 90 caused by the grinding process can be prevented, too. Since no chemical is used, there is no need of the disposal of a waste liquid and anti-chemical measures, thereby reducing the cost. The accuracy of the finished thickness can be increased.

Title: Fuel feed controller for internal combustion engine
Inventor: FURANKU AARUBOORUN
IPC: F02D41/14
Filed: 1989-03-17
Abstract: PURPOSE: To prevent control vibration having a frequency dependent on a resonance frequency of a control system by stopping fuel supply control when a period of time determined corresponding to operation state of an engine has elapsed. CONSTITUTION: A counter 32 starts clocking from a point of time when a primary differential value of a rotation speed exceeds a threshold value of the rotation speed and a solenoid of a control element 30 is turned on in response to a signal from a comparator 22. On the other hand, a threshold vale 36 is determined by a multi-dimensional map data generator 34 for generating data corresponding to each kind of operation parameters of an engine. When an enumerated value of the counter 32 reaches the threshold value 36, comparator 38 inputs a signal into an input terminal of an OR-gate 40. Only when the primary differential value of the rotation speed remains greater than the threshold value of the rotation speed, the OR-gate sends the signal to an reset terminal R of a SR flip flop 24 so as to shut off the solenoid of the control element 30, thus stably suppressing abnormal vibration.
