Patent JP-S61277978-A (JP)
Title: Image forming device
Inventor: HANADA SHINJI
IPC: G03G15/08
Filed: 1985-06-04
Abstract: PURPOSE:To prevent much toner from sticking in no-image areas by setting the DC component of the developing bias in no-image areas so that the DC components has the same polarity with the potential of a photosensitive body and is smaller in absolute value than a development start voltage during negative-positive image formation and also has the same potential with the photosensitive body potential and is larger in absolute value than the development start voltage during positive-positive image formation. CONSTITUTION:When positive toner is used, normal development is performed in an area (a) where the absolute value of the photosensitive body potential is larger than that of the DC component of the developing bias, and reverse fogging occurs in an area (c) where the photosensitive body potential is about >=-300V lower than the DC component of the developing bias to cause a little toner to stick. The development start potential is as high as the boundary between the areas (a) and (b), i.e. the photosensitive body potential and a reverse fogging start potential is as high as the boundary between the areas (b) and (c), i.e. about 300V higher than the photosensitive body potential. Similarly, when negative toner is used, the development start potential is as high as the boundary between areas a' and a', i.e. the photosensitive body potential and the reverse fogging start potential is as high as the boundary between areas b' and c', i.e. about 300V lower than the photosensitive body potential. Consequently, excellent images are obtained without consuming unnecessary toner nor causing contamination, etc., in the device.

Title: Data copying/comparing system
Inventor: KOJIMA SHUJI
IPC: G06F3/06
Filed: 1989-05-12
Abstract: PURPOSE:To shorten an operation time by switching a data bus with a data read signal from a magnetic disk control adapter and reading, writing, and comparing data. CONSTITUTION:When a host device sends an indication for copying data to a magnetic disk device 61 from a magnetic disk device 60, a data bus indication part 40 sends an indication for selecting data from a magnetic disk control adapter 50 to an FIFO input selector 70 and instructs the FIFO output selector 71 to output data to the magnetic disk adapter 51. Selectors 70 and 71 forms a data bus from the adapter 50 to an adapter 51 through an FIFO memory 20 and the reading operation of the adapter 50 and the writing operation of the adapter 51 are performed simultaneously. When the host device indicates the comparison between the data of the devices 60 and 61, the selector 70 selects, for example, the precedent adapter 50 under the control of the indication part 40 and a selector 73 selects the adapter 51 to compare data.

Abstract: PURPOSE:To obtain cast steel having excellent corrosion resistance and anti-wear property under acidic corrosive environment and high hardness, by specifying the ferrite  content of ferrite-austenite two-phase cast steel and containing Al therein to create precipitation hardness of a Ni-Al type intermetallic compound. CONSTITUTION:This cast steel consists of, on the wt% basis, 0.1 or less C, 0.5-1.5 Si,  0.5-1.5 Mn, 22-28 Cr, 8-15 Ni, 1.5-3.5 Mo, 0.8-2.0 Al and the remainder of iron  and inevitable impurities and is adjusted to 40-70% in the volume ratio of ferrite and  subjected to precipitation hardneing treatment at 470-630 deg.C after solid solution treatment. herein, Al imparts precipitation hardening property as referred above as well as  enhances anti-wear property and necessitates the lower limit amount or more but, if  the upper limit amount thereof is exceeded, oxide is formed during casting as well as  flowability and an Al yield are lowered and ferrite phase is increased too much  and  anti-wear property is lowered. When the ferrite volume ratio is below the lower limit,  precipitation hardening is small as well as a wear reduction amount is made large and,  if the upper limit thereof is exceeded, embrittlement is made remarkable and corrosion  resistance is lowered. If the temp. of hardening treatment is out of the aforementioned  range, sufficient hardness is not obtained.

Title: Fuel injection control device
Inventor: ISHIDA KATSUMI
IPC: F02D41/22
Filed: 1989-05-15
Abstract: PURPOSE:To prevent engine stall by providing a replacing means which makes a predetermined substitute value a detection value of engine load when the engine load more than a discrimination value for detecting abnormality is detected by a comparing means. CONSTITUTION:When abnormality of an engine load sensor output VPH is generated at a time t1 when engine revolution number is lower than Nx, for example, N1, the output VPH is raised though intake pressure is not actually raised due to trouble of an intake pressure sensor 8, and fuel injection amount operated using this output VPH is also raised. And when it reaches a time (t2a) when the output VPH reaches an abnormality discrimination value Vh2a on the upper limit side, the output VPH is replaced by a substitute value by a route shown by a broken line. As a result, the fuel injection amount becomes a predetermined amount of Tp3 from Tp2 by a route shown by a broken line. Thus, as generation of abnormality is promptly detected and measures are taken, the abnormality is dealt with before generation of engine stall and the engine stall is prevented.

Title: Method for polling system information transmission
Inventor: KATSUMATA NORIAKI
Filed: 1985-06-04
Abstract: PURPOSE:To prevent the reduction in transmission efficiency by shifting sequentially the presence of a fault at each circulation of call of all slave stations so as to prevent the fluctuation of time until all the slave stations is finished for call. CONSTITUTION:When a master 1 confirms a fault of a remote 2 while the remote 2 is a fault detection object at the 1st cycle, the remote 3 is called immediately, the information is transmitted with the remote 3 and then the remote 4 is called. The remote 2 is not called at the 2nd cycle and the call of the remote 3 is transferred immediately. The operation above is applied similarly at the 3rd cycle. When the remote 2 is for the fault confirmation object at the 4th cycle, the master 1 calls the remote 2 and discriminates it whether the fault is consecutive or restored depending on the presence of an acknowledgment signal ACK. When the fault is restored, the information is sent between stations.

Title: Information reader
Inventor: KASHIWAGI KAZUO
IPC: G03B27/32
Filed: 1989-05-15
Abstract: PURPOSE:To improve the accuracy of an input task as well as the input efficiency by deciding whether a medium to be recorded should be recorded or not corresponding with the read contents of a 1st reading means which reads the code information on the medium and a 2nd reading means which reads the presence/absence of the code information on the medium. CONSTITUTION:A bar code recognizing part 6d serves as a 1st reading means which analyzes the bar codes out of the converted digital signals. Then a bar code presence/absence detecting part 6e serves as a 2nd reading means which reads the presence/absence of bar codes. Thus it is decided whether the medium to be recorded should be recorded or not corresponding with the read contents of both means 6d and 6e. Therefore even the medium to be recorded and originally containing no code information can be surely recorded. Consequently, an input task is accurately carried out together with the omission of the input tasks caused by the useless manual operations. Then the processing time is shortened and the input efficiency is improved for an information reader.
