Title: Oxidation resistant sintered compact of powder
Inventor: KONO TOMIO
IPC: B22F3/10
Filed: 1993-06-01
Abstract: PURPOSE:To impart oxidation resistance in a high temp. region comparable to that of Ni-contg. stainless steel by compacting and sintering Cr-contg. iron powder having a specified compsn. not contg. Ni to certain high density. CONSTITUTION:Iron powder consisting of 0.7-2.5wt.% Si, 16.0-25.0wt.% Cr and the balance Fe with inevitable impurities is compacted and sintered. In order to regulate the relative density of the resulting sintered compact to >=91%, the iron powder is formed by a water atomization method and compacted under about 5-8ton/cm<2> pressure without using a binder. The sintering is carried out in vacuum or in an inert atmosphere and the sintering temp. is preferably set at 1,150-1,300 deg.C. By this method, the objective sintered compact having oxidation resistance comparable to that of SUS 310S is produced at a low material cost and a low production cost.

Abstract: PURPOSE: To prevent the fluctuation in the output voltage of an element by connecting diodes in parallel in a series circuit made by a Hall element and a temperature compensation resistor, and selecting the value of the temperature compensation resistor as specified.  
     CONSTITUTION: Temperature difference is T, the input resistance of a Hall element H is r i , temperature coefficient is 2, temperature coefficient of a diode D is δ, magnetic flux density is B, product sensitivity at temperature t 0 is K 0 , and the diode current is constant. Under these conditions, if k=1-K 0 B/r i0 , then V=E 0 (1+8T)- (E 0 k/2)[(1+δT)(1+αT)/(1+αT)+R1/r i0 ] is obtained. If dV/dT is obtained, then, conditions for V 0 /dt=0 for the output voltage V 0  is obtained, considering only for a dc component with B=0, i.e. k=1, and necessary approximation is made in the vicinity of the temperature t 0 ; R1=r i0  [α/δ-3±[(α/δ-3) 2 -8] 1/2 ] ÷4 is obtained. In the case a compensation resistance value is set to the said value, the output voltage V 0  does not vary due to the temperature cgange.

Filed: 1990-05-22
Abstract: PURPOSE:To enable an outline font data to be reused by a method wherein the prepared outline font data is temporarily stored in a RAM and when the same letter is printed, the outline data stored in the RAM is outputted. CONSTITUTION:When a letter code data or the like is supplied from a print data preparation device 12, a font data controller 14 judges whether it is required to be converted to an outline font or not. For a letter to be outputted as the outline font, whether an outline font data exists in a memory 15 or not is checked. In the case where it exists in the memory 15, said outline font data is read out from the memory 15, which expanded to a printing dot pattern data. It is outputted as the printing pattern data to the print data preparation device 12, and the outline font data is additionally written to the tail of the memory 15.

IPC: C01G49/02
Filed: 1985-06-18
Abstract: PURPOSE:To perform reducing process safely by a method wherein a surface active agent containing one carboxyl group in molecular formula is bonded on the surface of oxy iron hydroxide powder to be heat-treated. CONSTITUTION:When a surface active agent containing one carboxyl group in the molecular formula thereof as a fatty acid salt base anionic surface active agent or fatty group amine salt base cationic surface active agent is bonded on the surface of goethite powder to be heat-treated with inert gas flow, the surface finishing agent can fulfill the sinter-preventing function of the powder as well as the reducing function. The heat-reducing temperature shall be 300-700 deg.C and preferably within the range of 400-600 deg.C. When the heating temperature is insufficient, not only the heat-treatment time shall be extended but also the reducing function shall become insufficient, deteriorating the final saturated magnetization as well as coercive force while when the heating temperature is excessive, not only the particles shall be sintered remarkably but also the particle shape as well as the coercive force shall be deteriorated. Finally the produced magnetite powder can be slowly oxidized in the air at the temperature of 100-500 deg.C to produce maghemite powder.

Title: Interuption control circuit system
Inventor: DOUMOTO TAKASHI
IPC: G06F9/48
Filed: 1977-11-02
Abstract: PURPOSE: To detect the presence or absence of the interruption for the control circuit in the operator console by detecting the partial toruble of the interruption interval matching line based on the output of the interruption request line and the final stage device and then delivering the individual selector line to each device from outside.  
     CONSTITUTION: The interruption circuit is formed with control part 1 and plural units of devices 2-1W2-n, and the interruption detecting signals which are transmitted in sequence from part 1 to devices 2-1W2-n are produced at interruption interval matching line 3. Devices 2-1W2-n generates the interruption at interruption request line 4 for part 1 in case the devices have some interruption. Thus, the detection signal is prevented from being propagated to devices 2-1W2-n of the next stage. Then the detection signal output of device 2-n in the final stage is sent back to part 1 via interruption answer back line 12, and the individual selection signal is generated to devices 2-1W2-n to draw in the interruption from part 1 when the logical sum is O between the interruption detection signal and the interruption request signal.

Title: Slip issuing device
Inventor: YAMAGUCHI KIYOMITSU
IPC: G06Q50/00
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To attain reduction of development load of products, low prices and reduction of working time by discriminating a kind of job to be performed in printing a slip and carrying out printing for a title column of the slip to validate the title of slip to be issued in a target job. SOLUTION: A slip form is a copying paper, having a slip item column printed in advance, and an unified slip form 1 with a slip title column 1-2 which has each title printed in advance for every kind of slip to be issued for each job performing each slip issuing of a sales registration job, a delivery registration job, a buying and returning registration job and a transport registration job. Then, in printing a slip, a kind of job to be performed is discriminated, a character for deletion is overprinted on every title except for a title of a slip to be issued by a target job and the title of the slip to be issued by the target job is only validated. Thus, regardless of kinds of slips, a kind of slip form 1 is used to issue every kind of slip.  In consequence, a logic program regarding a slip printing can be used in common and preparation of a program for a printing logic for each kind of slip becomes unnecessary.

Next, a developing unit 3a is supplied with a cyan toner by a toner-circulating mechanism, and the paper 1 is passed on the unit 3a, whereby the cyan toner is adhered to the latent image to obtain a visible image. When printing in cyan is finished, the roller 8 is stopped, the cyan toner is recovered from the developing unit by a toner-recovering mechanism, and the developing unit is stopped in the condition of being out of contact with the paper 1. Thereafter, the paper 1 is fed backward. By this, the recording paper 1 is prevented from being stained with toners.

Title: Detection of high-frequency reflected power
Inventor: OOTA KIYOSHI
IPC: G01R21/01
Filed: 1985-06-17
Abstract: PURPOSE:To correctly detect reflected power regardless of the length of a transmission line and the mismatching position of impedance by selecting the max. value of the values detected by plural reflected power detecting circuits inserted in series into a transmission line. CONSTITUTION:The reflected power detecting circuits 3, 4 are provided in the positions apart from each other by lambda/4 (lambda is the wavelength of the high-frequency power to be transmitted) on the transmission line between a power amplifier circuit 2 and an antenna output terminal 5. Detection signals 103, 104 change according to the distance from the output terminal 5 to an impedance mismatching point if said discharge is changed. A selection circuit 6 selects the larger value of the signals 103, 104 and outputs the same as a reflected power signal 106. The signal 106 fluctuates extremely less in level as compared to the signals 103, 104. The reflected power is thus correctly detected without making adjustment with each of apparatus even if radio communication apparatus having the different lengths of the transmission line from the terminal 5 up to the antenna are used.
