Title: Display system for unused program number
Inventor: SHIMIZU TOMOHIRO
IPC: G06F11/28
Filed: 1978-08-23
Abstract: PURPOSE: To realize the display for the unused program numbers by installing the program memory device to memorize the supplied program information plus the means to read the contents of the program memory device and then detect the program numbers which are already written.  
     CONSTITUTION: When the program is written, the address designation code signal of ROM32 is transmitted from the control part via address part 21 and with operation of key input part 10. And the program number is read out of ROM32 to be written into the X register of RAM25. Then the address of RAM 31 is designated, and the contents of the address is read out to the Y register of RAM25. A decision is given at operation/judge part 24 to the numbers already written in RAM31 among all program numbers which are set first to the X register, and the unused program numbers are sent to display driving circuit 33 to be displayed at display part 33. In such way, the same program number is never used mistakenly, thus avoiding the programing error.

Title: Transfer device for electrophotography
Inventor: TAKEKIDA YOSHISUKE
IPC: G03G15/14
Filed: 1978-08-22
Abstract: PURPOSE: To obtain a transfer device for electrophotography having a simple constitution, high reliability and high efficiency without causing transfer unevenness, by bundling conductive thin fibrous wires into a brush form, and lightly pressing to the photoreceptor from the back of the material being transferred.  
     CONSTITUTION: A bundle 11 of conductive thin fibrous wires is shaped into a brush form by means of a holder 12, and is positioned so as to lightly press against a photoreceptor 1 from the material being transferred, i.e. from the back of a paper 6. A lead wire 13 is connected with the bundle 11 of fibrous wires within the holder 12. When a potential is applied to the lead wire 13, the potential is applied to the boundle 11 of wires, so that the toner image on a photoreceptor 1 is transferred on the paper 6. The bundle 11 of wires ia made of conductive fibrous material, which is mostly carbon fibers or stainless steel fibers measuring about several microns to scores of microns in diameter. Thus, because of the fine wires, frictional resistance with the paper 6 is small. Besides, since innumerable wires contact with the paper 6, transfer unevenness never occurs. In addition, the constitution is simple and the reliability is high.

Title: Semiconductor memory
Inventor: OTSUKA NOBUAKI
IPC: G11C11/41
Filed: 1992-04-22
Abstract: PURPOSE:To prevent the pulse width of a latching signal from being affected by means of the power source noise of an output circuit by permitting power source noise not to occur in an output circuit power source line when a pulse generating circuit is generating an output latching signal. CONSTITUTION:When the output circuit power source line 14 and an inner circuit power source line 15 are branch-wired, the power source noise of the power source line 14 occurs at the time of changing-over output data in the output circuit 11 and the power source noise of the power source line 15 occurs at the time of operating an inner circuit 12. Therefore, when the inner circuit 12 such as an address input circuit, an address decoding circuit, a word line selection driving circuit in memory cell array, a sense amplifier 17, etc., is operated immediately after the change-over of an address signal input, a voltage drops in the power source line 15. After the latching signal LAT is risen, the voltage drops in the power source line 14 at the point of time when output data is changed-over. Since power source noise does not occur in the power source line 14 during the generation of the signal LAT, the pulse width of the signal LAT is not affected by the power source noise of the circuit 11.

Title: Electric current detector
Inventor: SHIMIZU TOSHIHISA
IPC: G01R15/20
Filed: 1982-06-17
Abstract: PURPOSE:To enable the exact detection of DC and high frequency current having a large transient fluctuation, by removing the electromagnetically induced voltage component owing to the fluctuation in magnetic field from the electrical output obtained from a magneto-electric transducer. CONSTITUTION:Two routes, i.e. the lead wires wherein the electromagnetic induced voltage induced in lead wires 17, 18 for leading out the Hall voltage of a Hall element 3 placed in a magnetic field is induced positive, and the lead wires wherein said voltage is induced negative, are made in an electric current detector using the Hall element 3 as a magneto-electric transducer. These two voltages are added under control with resistors R1, R2 at the lead wire output terminal 16 of the element 3 to offset the electromagnetic induced voltages so that only the Hall induced voltage appears at the lead wire terminal 16 of the element 3. The DC and high frequency current having a large transient fluctuation are thus detected exactly.

Title: Colorant for pressure-sensitive, heat-sensitive recording paper
Inventor: TSUJIMOTO MICHIHIRO
IPC: B41M5/136
Filed: 1980-07-29
Abstract: PURPOSE:To obtain the titled colorant, which is excellent in colored image retention, light resistance, plasticizer resistance, etc., as compared with colorants based on crystal violet lactone, by using a specific triphenylmethane. CONSTITUTION:A triphenylmethane (e.g., as represented by formula IV or V) of formula I or II (where X is H, a halogen, methyl group, or methoxy group, R1 is H or methyl group, and R2 is phenyl or benzyl group, or R1 and R2 together may form a group of formula III) is used as a colorant for pressure-sensitive heat-sensitive recording paper. The colorant having a mechanism of developing color when contaced with atmospheric oxygen, different from lactone-type compounds, takes time to develop colors. Thus, the signal use of the colorant is not suitable for the case where quick color development is required, but the combined use of this colorant as a secondary agent with lactone compounds is very promising.

Electron waves enter the potential barrier at different angles along a lens, corresponding to the position and exit from there at different angles due to the shape of the potential barrier, and the electron waves are focused on at a focal point on the axis as an overall effect.  Then, in the case of changing the potential from a voltage source 2 to vary the speed of the electron waves under the electrode 2, the focal point of the structure is changed from F1 to F2 or to F3. Thereby different effects are imparted to the electron waves.
