Title: Semiconductor integrated circuit device
Inventor: NAKAI TADASHI
IPC: H01L27/08
Filed: 1986-12-05
Abstract: PURPOSE:To increase latch-up strength by forming a high-concentration impurity region having the same conductivity type as a low-concentration impurity region while being brought into contact with the base of at least one conductivity type low-concentration impurity region in low-concentration impurity regions having different conductivity types. CONSTITUTION:A low-concentration N-type impurity region 2 and a low- concentration P-type impurity region 3 are formed onto a low-concentration N-type semiconductor substrate 1, and a high-concentration N-type impurity region 24 is shaped brought into contact with the base of the low-concentration N-type impurity region 2 while a high-concentration P-type impurity region 25 is formed brought into contact with the base of the low-concentration P-type impurity region 3. Since the high-concentration N-type impurity region 24 and the high-concentration P-type impurity region 25 are shaped through a diffusion or other methods, low resistance by the high-concentration N-type impurity region 24 is added while low resistance by the high-concentration P-type impurity region 25 is added. Accordingly, currents required for turning a parasitic transistor ON are increased, thus improving latch-up strength.

Title: Exhaust emission control device for internal combustion engine
Inventor: HIROTA SHINYA
IPC: F01N3/24
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To raise the temperature of a catalyst for controlling exhaust emission rapidly. SOLUTION: A honeycomb structured thermal storage material 4 made of silicon carbide is provided in an exhaust pipe 1 upstream of an exhaust emission controlling catalyst 2, and a nozzle 11 and a glow plug 12 of a burner 10 are provided in an exhaust pipe 1 upstream of the thermal storage material 4. Air-fuel mixture is injected from the nozzle 11 before cranking in starting an engine. With the air-fuel mixture ignited by the glow plug 12 and the burner 10 operated, the thermal storage material 4 is heated by blowing the flame F of the burner 10 to the thermal storage material 4 to store the heat of the flame F in the thermal storage material 4. After storing the heat of the flame F in the thermal storage material 4, the operation of the burner 10 is stopped, and cranking is performed immediately to start the engine.  When the low temperature exhaust emission exhausted when the engine is started passes through the thermal storage material 4, the temperature of the exhaust mission is raised due to the heat of the thermal storage material 4. The exhaust emission whose temperature having been raised raises the temperature of the catalyst 2 when passing through the catalyst 2 to activate the catalyst 2.

Filed: 1989-11-09
Abstract: PURPOSE:To enable the automatic mounting of a thin-type work to core iron by a robot by bringing the work and a core iron protruding part into mutual contact dislocating their axes slightly, and performing relative sliding to fit the work axial hole at the core iron protruding part while guiding the inner peripheral surface of the work axial hole by the outer peripheral surface of the core iron protruding part. CONSTITUTION:In case of mounting a thin-type upper blade 3, with an axial hole provided at its center part, at a core iron protruding part 1 automatically by a robot, the upper blade 3 is brought into contact with the core iron protruding part 1 in the state of the axes of the upper blade 3 and core iron protruding part 1 being slightly dislocated to each other. When the upper blade 3 is slided in the direction of an arrow mark A in this state, the axial hole inner peripheral surface of the upper blade 3 is guided by the outer peripheral surface of the core iron protruding part 1, and the axes of the upper blade 3 and core iron protruding part 1 come to coincide with each other, thus enabling the fitting of the upper blade 3 at the core iron protruding part 1. In this case, it is better to slide the upper blade 3 in the direction of the arrow mark A while pushing two points C on the upper blade 3. The upper blade 3 can be thus mounted at the core iron protruding part 1 positively and easily.

Title: Mos field-effect transistor
Inventor: MURAO YUKINOBU
IPC: H01L29/43
Filed: 1988-11-18
Abstract: PURPOSE:To prevent deterioration of characteristics obtained by making a MOS transistor fine by a method wherein a gate electrode is formed of two kinds of materials whose work function is different. CONSTITUTION:A work function of molybdenum silicide 13 is by about 0.5V larger than that of polycrystalline silicon 12. On the other hand, in a state that a drain voltage has been applied, a threshold voltage Vr of a transistor is decided by the threshold voltage Vr decided by the work function of the polycrystalline silicon. Since the work function of the molybdenum silicide is large, a decrease in the threshold voltage Vr by a short channel effect at a short channel length can be suppressed by a polycrystalline silicon gate MOS transistor of an identical channel length. Thereby, it is possible to prevent characteristics from being deteriorated by being made fine.

CONSTITUTION:The radio wave absorbing body 1 formed by adhering both the two kinds of ferrite tiles 2, 3 formed to be a square shape or a rectangular shape with different radio wave absorbing center frequency in a checkered pattern is provided at least on a wall face and a ceiling face. Since the two kinds of the ferrite tiles 2, 3 differ from the radio wave absorbing center frequency and cover the different frequency bands, the radio wave absorbing body 1 formed by arranging the tiles in a checkered pattern offers an excellent absorbing characteristic over a wide band as a whole. Moreover, the arrangement of the tiles in the checkered pattern acts like eliminating the change in the absorption performance depending on the direction of the magnetic field of an incoming radio wave. Furthermore, since the ferrite tiles 2, 3 are in use, a small-sized radio wave dark room is constituted.

Title: Optical scanner
Inventor: SUZUKI MAKOTO

Filed: 1990-10-29
Abstract: PURPOSE:To reduce the size of a tilting mirror in a simple structure and to use a light guide wave passage of small core diameter by shortening the wavelength of a light source. CONSTITUTION:Light is deflected at an equal angular velocity by a light beam rotation reflecting mirror 14 from a light source 11, which is generated based on image information, and whose wavelength is shortened by a non-linear device, and is injected in order into a light guide passage alley 15, so as to be transmitted in a light guide passage, and comes out of an outgoing end 15b, and a photosensitive material 20 is thereby irradiated. Since the wavelength of the light to be reflected is shortened, the reflecting surface of the rotation reflecting mirror 14 may be small, while the diameter of a core 16a of the light guide wave passage 15 may be small. The size of a tilting mirror, i.e. of a rotation reflecting mirror can thus be reduced, or otherwise, the light guide passage as well as the core diameter of a light guide wave passage alley can be reduced.
