Title: Famos semiconductor device
Inventor: MARUYAMA AKIRA
IPC: H01L27/115
Filed: 1990-07-20
Abstract: PURPOSE:To prevent the deterioration of write characteristics even in the case where a threshold voltage of a FAMOS is lowered by forming a region having a higher impurity density than a substrate in a part of a junction of a drain section and a channel section. CONSTITUTION:First, ion having conductivity the same as the conductivity with a substrate and an impurity density that is higher than that of the substrate is implanted into a region 10 on the substrate 1. Then, a floating gate 4 and a control gate 5 are formed. Next, ion having such an impurity with conductivity opposite to that of the substrate is implanted into a drain section 3 and a source section 2. In this case, an impurity density of the drain section 3 is two or three digits higher than that of the region 10. Therefore, an overlapped area of the region 10 and the drain section is an impurity region of the drain section since an impurity of a region 9 is negated by that of the drain section. Therefore, a region having conductivity the same conductivity with the substrate and an impurity density higher than that of the substrate is the region 9. When the region 9 such as this exists, the width of a depletion layer near the drain section can be made narrow at the time of writing for placing hot electrons in the higher field even in the case that the density of the substrate is decreased for lowering a threshold voltage of a FAMOS.

Filed: 1990-07-19
Abstract: PURPOSE:To miniaturize a test signal generating section and a test signal detection section and to reduce power consumption by using a DC voltage in place of a PN pattern as a test signal. CONSTITUTION:The system consists of a test signal generating section 2, a sending end switching section 3, a standby transmission logic section 4, a standby reception logic section 5, a reception switching section 6 and a test signal detection section 7. Then the standby transmission logic section 4 inserts relevant detection information to a designated time slot in a prescribed frame format signal when a 1st DC voltage detection section 41 detects a DC voltage from a DC voltage superimposing section and sends the result to a reception side and the standby reception logic section 5 sends a relevant DC voltage to the test signal detection section 7 when the information detection section detects the detection information from the reception signal, the test signal detection section 7 uses the DC voltage detected by a 2nd DC voltage detection section 71 to monitor the connection state of the standby system. That is, the DC voltage is used in place of a PN pattern as a test signal. Thus, the test signal generating section and the test signal detection section are miniaturized and the power consumption is reduced.

Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To greatly improve the productivity by forming a surface, to which another magnetic head chip is to be stuck, as a base of shape provided with a slight inclination relative to a surface to which magnetic head chip is to be stuck. SOLUTION: A change in distance a2 ' by 1.8μm is resulted by changing the size of a distance C by 10μm when the angle θof the flat surface 2 and slope 3 of the base 1 is 10 deg.. Then, the control to keep this distance at an allowance of about ±5μm of a difference DA in level between tracks is easily executed. A change in the inter-gap distance GL between the first magnetic head chip 8 and the second magnetic head chip 9 is eventually resulted if the size of the distance C is changed, but the allowance of about ±5μm of the inter-gap distance GL is maintained by moving the first magnetic head chip 8 by the same distance as the distance at which the magnetic head chip is moved for the purpose of adjusting the position of the second magnetic head chip 9.

Title: Converter blowing method
Inventor: NITTA MASAKI
IPC: C21C5/30
Filed: 1987-07-31
Abstract: PURPOSE:To reduce recovery loss of exhaust gas especially at early blowing stage by specifying operational condition in a converter at the time of executing converter blowing by using the pretreated molten iron. CONSTITUTION:Oxygen gas supplying velocity at the early blowing stage from start of blowing to start of the recovery of exhaust gas is adjusted to 0.015-0.035Nm<3>/ ton.sec. By restraining the above oxygen supplying velocity to less than the upper limit, the decarburizing reaction during the stage from the start of blowing to the start of recovery of the exhaust gas is suitably restrained, and CO gas generating quantity during this stage is remarkably reduced. However, as the early blowing stage is executed in order to raise the exhaust gas composition to effective concn. for recovery so that the exhaust gas composition does not passes through the explosion range, if the condition, in which the suitable decarburizing reaction can progress, is not set, the important part of the early blowing stage is not played. Under this viewpoint, the oxygen supplying velocity is necessary to be more than the lower limit. Therefore, this method raises CO gas concn. in the exhaust gas while suitably restraining the decarburizing reaction by setting the oxygen supplying velocity as the above-mentioned and the recovery of the exhaust gas is started at the time of reaching effective CO gas concn. to the recovery of the exhaust gas.
