Title: Accumulating method for hydro-pneumatic main accumulator
Inventor: MIMUKAI KEN
IPC: B60G17/04
Filed: 1986-06-30
Abstract: PURPOSE:To effectively utilize the pump capacity, by stopping the operation of a pump at a full charge pressure, and after a short dead time, repeating the start and stoppage of the operation of the pump. CONSTITUTION:When an inner pressure P of an accumulator 1 becomes equal to or less than a charge starting pressure Pin, an unload valve 2 is closed to start accumulation to the accumulator 1. When the inner pressure P of the accumulator 1 becomes equal to or greater than a full charge pressure Pout, the current to the unload valve 2 is cut, and after a fixed time is elapsed, the unload valve 2 is repeatedly opened and closed several times. Accordingly, a stable balanced condition may be obtained during the period from a full charge pressure region to a balanced condition pressure, thereby suppressing a reduction in full charge pressure. Accordingly, an oil pump may be used at a high pressure with the same capacity, thus effectively utilizing a pump capacity.

Title: Semiconductor functional element
Inventor: ARAI KUNIHIRO
IPC: H01L29/06
Filed: 1995-06-21
Abstract: PURPOSE: To provide a semiconductor functional element which has a single-peak current-voltage characteristic and can sufficiently suppress the increase of an electric current when an applied voltage is higher than the valley voltage by providing a barrier layer of an undoped semiconductor to which no impurity element is added between a semi-insulating semiconductor substrate and a collector layer. CONSTITUTION: When an undoped InAlAs layer 2 is interposed between a semi- insulating semiconductor substrate 1 and an n-type InGaAs layer 3, the pinch-off effect of the substrate 1 on the electrons flowing in the layer 3 in the lateral direction can be intensified, because a barrier which prevents the leakage of electrons to the substrate 1 side is provided and the barrier surely encloses electrons within the layer 3. In other words, the increase of electric current can be sufficiently controlled when a voltage higher than the pinching-off voltage is applied and a current-voltage characteristic having a single-peak current characteristic can be realized easily.

Abstract: PURPOSE:To assure a positive operation of a non-volatile memory by a method wherein the number of operations of revising data in the non-volatile memory is counted every time the revising is carried out and as the number of revising exceeds a predetermined number of times, the data is transferred to a non-used area. CONSTITUTION:An address to be stored is read out from a non-volatile memory 2, stored in an index register 6, the number of times of revising is read out from the memory 2 and stored in a CNT register 7. The number of times of revising is increased by one and it is tested if the revising time exceeds a revising assurance time, for example, 10,000 times. If the times do not exceed it, the revising times increased by one and the cooking data are written into the same area. If it is judged that the times exceed 10,000 times, the revising times exceed the assurance value, resulting in that it is required to write data in a new area. Then, the last area in the area being operated at present is searched out. That is, all the addresses to be stored are read out for all the cooking numbers so as to get their maximum value. Number of data is added to the maximum value and the added value is stored in a register 6. In this case, the register 6 indicates a leading address in the area not being used.
