Title: Mixed-gas controlling apparatus for internal-combustion engine
Inventor: TAKIZAWA SATORU
IPC: F02D41/12
Filed: 1982-07-05
Abstract: PURPOSE:To prevent reduction of torque and prevent generation of engine stall by feeding intake air by opening a by-pass passage and making correction-control of the air-fuel ratio to the lean side if the number of engine revolution reduces with a throttle valve perfectly closed. CONSTITUTION:When a throttle valve switch 18 is turned ON, the average value n of the revolution number N of n-units of engines which are memorized in a memory 38 is calculated, and the newset number N of engine revolution together with a set value DELTAN are compared, and if N<n-DELTAN, the output of an arithmetic circuit 35 becomes ''N'', and a solenoid control valve 32 is opened through a transistor 37, so as to allow communication of the by-pass passage of a throttle valve. Therefore, when the number of engine revolution reduces in the perfect closed state of the throttle valve, air is supplied through a by-pass air passage, and the retardation of increase of the air amount with respect to the succeeding increase of the fuel injection amount is corrected, and sharp reduction of the air-fuel ratio, namely over-rich condition is prevented. Thus, generation of engine stall and other trouble in engine operation can be prevented.

Title: Method and device for processing picture
Inventor: ISHIDA SHINICHI
IPC: B41J2/52
Filed: 1988-05-11
Abstract: PURPOSE:To reproduce the satisfactory picture of high resolution with simple constitution by outputting picture data, which has been quantized by means of an error diffusion method, through the use of a thermal head printer. CONSTITUTION:The thermal head printer 7 records binarization data which has been binarized by the error diffusion method in a read part 1. In the case of the thermal head printer, the diameter of printing dots become large in a dark part where there are many black dots in a periphery picture element, and the diameter of the printing dots become small in a highlight part where there are less black dots. Thus, the occurrence of a stripe pattern which is peculiar to the error diffusion method can be prevented in the highlight part, and a void between the dots can be prevented in the dark part, whereby the satisfactory picture can be reproduced.

Title: Cartridge for correction ribbon of typewriter
Inventor: REMO FUARUKONIERI
IPC: B41J33/52
Filed: 1989-05-09
Abstract: PURPOSE: To optimize tensioning and forwarding operations of a correction ribbon by receiving a resistance due to movement of a cartridge to mount it on a movable support of a machine by a thrust force. CONSTITUTION: A lever 67 is always received by a stress of counterclockwise direction by a force of a spring element, displaced from a first position to a second position and then third position. At this time, the lever 67 follows to the movement of a support 19. A distance of the support 19 moved from the third position to the first position is rotated clockwise against the force or the spring by engaging a front teeth 66 with a teeth 69. Thus, the lever 67 is rotated clockwise against the force of the spring. Thus, it is reciprocated between the teeth 66 and the teeth 69. Therefore, since the teeth 69 are engaged with the teeth 66, a receiving reel 39 is rotated only at a predetermined degree, and forwarding operation of the ribbon 13 is optimized.  However, a distance of the support 19 from the second position to the third position is insufficient to forward the ribbon 13 by engaging the teeth 69 with the front teeth 66.

Title: Removal of oxide scale
Inventor: SUMIDA HARUO
IPC: C02F5/08
Filed: 1980-08-25
Abstract: PURPOSE:To protect devices, pipings, etc. from damage in a power generating plant or the like, by lowering the concentration of an oxide scale-dissolving agent without lowering the dissolving speed of the oxide scale. CONSTITUTION:An object 1 from which oxide scale is to be separated, is dipped in a solution 2 containing an organic acid and a reducing agent in a dissolving vessel 3. The solution is circulated through a conduit 6 by a circulating pump 5, while light having a wave length in a range of from ultraviolet to near infrared is radiated from a xenon lamp 4. Thus, oxide scale is separated from the object 1. In the light source of the xenon lamp 4, a luminosity is large especially in a range of from near ultraviolet to ultraviolet where the light-absorbing intensity of the scale is large and the light absorption by the reducing agent itself is effected, so that the oxide scale is converted into an easily soluble excited state by absorption of the light energy. Consequently, a higher dissolving speed can be obtained even when the concentration of the dissolving agent and a temperature in the dissolving step are low, as compared with that in a conventional method.

Abstract: PURPOSE:To protect programs stored in an internal ROM by inhibiting the write to a memory space, an I/O space, or a register space while an instruction, which is read out from an external memory, stored in a buffer for the change of the mode is executed. CONSTITUTION:When it is detected by a mode switching control circuit 7 that the mode of operation where only an external memory 2 is used is switched to the mode of operation where only an internal ROM 1 is used, a multiplexer switching control signal line 8 is made active to switch a multiplexer 4 from the side of the external memory 2 to the side of the internal ROM 1. While all instructions which are stored in an instruction advance red buffer 5 and are read out from the external memory 2 are executed, a control signal line 9 is set to the low level to inhibit the output of the signal of an instruction decoder 6 to a write permission signal line 10. After execution of all instructions read out from the external memory 2, the control signal line 9 is set to the high level, and the write permission signal line 10 is set to the outputtable state for instructions read out from the internal ROM 1.

Abstract: PURPOSE:To obtain tolerance to an external disturbing magnetic field and perform high-density recording by making the surface of a recording medium recessed and projecting, and arranging a magnetic body which is not magnetized on at least projection part surfaces and forming magnetic parts and nonmagnetic parts substantially. CONSTITUTION:Recesses and projections corresponding to an information signal are formed in the surface of a disk base body 1 and a thin-film magnetic body layer 3 is formed on the surface of the base body 1. The recess and projection shape of the disk surface is maintained even after the magnetic body layer 3 is formed, and the magnetic body layer 3 is held in a nonmagnetic state. Consequently, pit parts become nonmagnetic parts 5 substantially because of the relation with a pickup and other parts become magnetic parts 4. The signal on this recording medium is reproduced by detecting variation in the magnetic resistance of the signal detection end part 37 of the pickup which has a permanent magnet 32 as the core when the end part 37 comes into contact with said recessed and projection parts.
