Title: Fuel injection control device
Inventor: TAKIZAWA SATORU
IPC: F02D41/26
Filed: 1982-05-11
Abstract: PURPOSE:To enable the air-fuel ratio to be properly maintained upon the condition of transition, by utilizing the data which is a basic amount of fuel injection including a past information, so that unequilibrium between the air-flow into an engine cylinder and the fuel injection amount is prevented. CONSTITUTION:An arithmetic device 2 which receives an intake-air flow theta and a rotational speed N, carries out the following computation for estimating the fuel injection amount. First, T1=K(Q/N) where K is a constant, is calculated. This T1 is transmitted to a memory 3 each time a reference pulse S4 is given, the newest N number of T1 values are stored, and the averaged value of them is computed. Next, compensating computation is carried out in accordance with various compesating factors K1, K2 for obtaining T2=T1.K1+K2. The T2 is delivered to a registor 4, as the value which corresponds to the actual fuel injection amount, thereby the air-fuel ratio has a proper value.

IPC: H03K19/096
Filed: 1980-06-09
Abstract: PURPOSE:To prevent the adverse effect between two logical circuits, by keeping the logical signal output point at off-state at floating, through the provision of a switching element between output lines of a common logical signal from one logical circuit consisting of MOSFETs to other two. CONSTITUTION:A logical output determined with logical signals applied to the gate of FETs 6, 8 is outputted, by applying a common output signal from the 1st logical circuit consisting of MOSFETs 1, 2, and MOS partial logical circuit 3 to the 2nd and 3rd logical circuits consisting of MOSFETs 4, 5, 6; 7, 8 respectively via signal lines 9a, 9b. This signal line 9b is provided with an MOSFET 12 connected to the drain of the partial logical circuit 3 for the source as a switching element, so that this can be held at off-state when the output point of the logical circuit 1 is floated. Thus, even if the output signal lines 9a, 9b are floated, no adverse effect is given between the 2nd and 3rd logical circuits.

Title: Rotating holder of substrate of molecular beam epitaxy device
Inventor: FUJIOKA KAZUMASA
IPC: H01L21/203
Filed: 1985-04-15
Abstract: PURPOSE:To curb the rise in temperature of a bearing element and to reduce the heat loss of a heater heating a substrate, by providing an element serving as a lead wire for electrifying the heater and a support for supporting the heater. CONSTITUTION:The heat from a heater 7 or a heater base 6, either of which is at a high temperature, is transmitted to a terminal plate 15 through an ele ment 8 serving as a lead wire and a support for the heater, and further it is transmitted to a bearing 10 through a holding plate 14 and a fixed shaft 4. Since the element 8 serving as a lead wire and a support for the heater has a large length, it renders a large heat resistance, and consequently the tempera ture is lowered sufficiently in the terminal plate 15. Since the element 8 has a sufficiently large diameter, in addition, the heat in the element 8 can be neglected substantially, and thus the fixed shaft 4 is not heated from inside. Therefore little heat is transmitted to the bearing 10, the temperature of the bearing 10 is kept at a remarkably low level, the reliability thereof is improved, and thus the lifetime of a holder is prolonged.

Title: Recording and reproducing device
Inventor: TAGAWA AKIRA
IPC: G11B27/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To simplify calculation attended with display of a recording time and a reproducing time or the like and to reduce the processing time attended with the calculation processing. SOLUTION: A CPU 3a of this recording and reproducing device records recording data from an audio processing IC 4 which a data amount (500 bytes) that is the n-th power of 2 (seconds) in time conversion of data stored per page to a data area for each page of an IC card 2 as its control. In the case of calculation for indication of a recording time and a reproducing time, the time can be calculated in an expression of number of pages ×1/2 sec. When the 8-bit CPU 3a executes this calculation procession, an instruction of '1-bit shift to the right' has only to be given to the CPU 3a for the calculation processing in this case. Thus, a multiplication instruction (bit shift) of the assembler required only 2 CPU clocks.  Since the calculation processing requires only a time equivalent to the 2 CPU clocks, the processing time attached with the calculation processing can remarkably be reduced more than that of a conventional technology.

Abstract: PURPOSE:To keep the size in an opened groove uniform by forming many protruded stripes continued along the longitudinal direction on the inner face of the opened groove of a guide member, crushing the protruded stripes at the time of bend machining, and offsetting the decrease of the size in the opened groove. CONSTITUTION:In a guide member, e.g., the guide 43 of a passive seat belt for an automobile, many protruded stripes 45a continued along the longitudinal direction on the whole inner face of its opened groove 45 are formed. At the bent portion of the guide 43, a bending mold not shown in the figure is slid on the bottom section 47 of the opened groove 45 and the face 49a on the second projection 51 side of the first projection 49 to crush them. The height of protruded stripes 45a is reduced from the height (d) of the linear portion of the guide 43 to the height (d1) of the bent portion. Protruded stripes 45a of the bent portion are crushed for plastic deformation, and the generation and accumulation of cutting chips during cut machining are prevented. The size of the inner diameter of the opened groove 45 is kept uniform, and the sliding resistance of a sliding member sliding in the opened groove 45 is reduced.
