Title: Idle speed control system for an engine
Inventor: OHKUMO HIROYA
IPC: F02D31/00
Filed: 1990-09-20
Abstract: A feedback control system has a wide dead zone (No I  DELTA N2/2) and a narrow dead zone No +/-  DELTA N1/2) with respect to a desired idle speed No such that the control of an idling speed control valve, ISCV, is halted when the idle speed is in one of the dead zones. When the idle speed is greater than an upper limit of the wide reference, and when the idle speed is smaller than a lower limit of the wide reference zone, the narrow reference zone is selected. When the idle speed is within the narrow reference zone, the wide reference zone is selected. The idle speed is compared with upper and lower limits of the selected reference zone, and controlled in accordance with the difference there-between. The control system quickly brings the idling speed to a desired value yet prevents hunting near that value.   <IMAGE>

Patent GB-2251308-A (GB)
Title: Sensors
Inventor: DAMES ANDREW NICHOLAS
IPC: G01N9/00
Filed: 1990-12-22
Abstract: A density sensor comprises a cavity arranged to receive the gas whose density is to be sensed. The cavity is divided into two chambers by a flexibly mounted diaphragm. A piezoelectric excitation device at one end of the cavity is used to excite the gas in the cavity into resonant vibration in a mode having an anti-node at the diaphragm, which causes the diaphragm to vibrate with the gas. Another piezoelectric device senses the vibration, whose frequency is a function of the known mass of the diaphragm and the density of and speed of sound in the gas. This last parameter can be sensed by exciting the gas in the cavity into resonant vibration in a second mode having a node at the diaphragm, so that the diaphragm does not take part in the vibration. Alternatively, it can be sensed by providing a second cavity, also arranged to receive the gas but not having a diaphragm, and resonantly vibrating the gas in the second cavity.

Title: Conductivity modulation type mosfet
Inventor: SEKI YASUKAZU
IPC: H01L29/78
Filed: 1991-12-12
Abstract: A conductivity modulation type MOSFET including a highly doped buffer layer (2) whose impurity concentration is at least 1 x 10<17> atoms/cm<3> so that the buffer layer (2) can function to reduce the injection efficiency of carriers to an adjacent high resistivity layer (3). This will prevent the carrier transport efficiency of the high resistivity layer (3) from decreasing, which is caused by the effect of lifetime killers, and shortens a turn-off time of the device. Thickness of the buffer layer (2) is made equal to or less than 15  mu m so as to prevent increase in the ON-state voltage of the device. Tradeoff relationship between the turn-off time and ON-state voltage of the device can be further improved by diffusion of a certain amount of lifetime killers and irradiation of charged particles. <IMAGE>
