Title: Differential control mechanism of differential gear for vehicle
Inventor: NAKAO TOSHIYUKI
IPC: F16H48/32
Filed: 1987-06-09
Abstract: PURPOSE:To enable an optimum differential limit under various running conditions to be optionally set by controlling the pressing force of a pressing member with which the plates of a multiple disk clutch are pressedly engaged. CONSTITUTION:Differential control is carried out by generating a differential control torque by engaging a multiple disk clutch 13, and controlling the relative rotation between a ring gear 12a and a side gear 12b of a differential gear 12. And the engaging force of the multiple disk clutch 13 is optionally set by the pressing force of a pressing member with which the plates of the multiple disk clutch 13 are pressedly engaged, thereby the differential limit in the differential gear 12 can be optionally set. Accordingly, by controlling the pressing force of the pressing member, an optimum differential limit under various running conditions, for instance, at the time of turning running, one wheel slipping running, or at the time of braking can be optionally set.

Title: Semiconductor nonvolatile memory
Inventor: KOJIMA YOSHIKAZU
IPC: H01L27/115
Filed: 1990-05-30
Abstract: PURPOSE:To make small the size of a memory and to make it possible to conduct a high-speed information readout by a method wherein a selector gate electrode and a floating gate electrode are arranged in parallel between source and drain regions and an increase in the density of the memory and the speedup of the memory are attained. CONSTITUTION:In case a memory is a non-selective one, the conductance of a channel formation region 3 of the non-selective memory can be always set into a small conductance by grounding the potentials of a selector gate electrode 10 and a control gate electrode 8. Accordingly, even if a voltage is applied to a drain region 4, an unnecessary charge is not injected in the region 3 because the inductance of the region 3 of the non-selective memory is set small. As this result, a high-speed information readout can be conducted. The reason why the conductance of the region 3 is small in a non-selective state regardless of the potential of a floating gate electrode 6 is because the conductance of the region 3 is controlled by the electrode 10.

Title: High frequency heater
Inventor: OTSUKA AKINORI
IPC: F24C7/02
Filed: 1986-06-19
Abstract: PURPOSE:To make it possible to stop heating right before a food catches fire by following up the amount of steam generated from an object that is being heated with a sensor and judging the change in the amount of steam and by a set-up that a microcomputer detects by the sensor information and information on the kind of cooking which is inputted from a cooking selection key the timing of ignition for foods by each kind of cooking. CONSTITUTION:When cooking starts with heating, the amount of steam generated from a food changes. When a food is heated to a certain extent, the increase in the amount of generated steam increases rapidly, and after a certain time has passed the steam generation decreases on the contrary and finally the food catches fire. A period of time T1 of cooking taken up to P point at which the steam generation changes and suddenly increases initially is reached is multiplied by a certain constant (K) to obtain a value T2. T2 is estimated to be the cooking time with additional heating Point Q at which heating is stopped is determined by T=T1+(T1XK)+A. Because the constant K is almost constant for the kind of food to be cooked, it is determined when the user depresses a cooking selection key.
