Title: A-d converter
Inventor: TAKASHIMA IZUMI
IPC: H03M1/18
Filed: 1984-10-22
Abstract: PURPOSE:To improve the resolution to an analog input signal low in level by applying a different upper limit reference voltage respectively to plural A/D converters having a prescribed bit to which an analog signal is inputted in common. CONSTITUTION:The input analog signal V1 is inputted in common to each data input terminal Vin of 8-bit A/D converters ADC1, 2, a voltage Vr is fed to an upper limit reference voltage terminal Vref of the ADC1 and a Vr/4 is fed to a terminal Vref pf the ADC2 while being divided by resistors 32, 33. When the signal V1 is within a range of Vr/4-Vr, an H level is outputted to an overflow terminal OF of the ADC2 and a digital signal of the ADC1 is outputted to terminals OD2-OD9 from the buffer 11. The output of a tri-stage buffer 12 is at a high impedance and terminals D0, D1 are fixed to logical 0 by pull-down resistors 40, 41. When the signal V1 is less than the Vr/4, the output of the buffer 11 shows a high impedance, the buffer 12 gives a digital signal of the ADC2 to the terminals OD0-OD7 and the level of the OD8,OD9 are fixed to logical 0 by resistors 42, 43.

Title: Fluorescent character display tube and manufacture thereof
Inventor: ITOU SHIGEO
IPC: H01J9/02
Filed: 1982-12-20
Abstract: PURPOSE:To obtain a fluorescent character display tube having no exhaust tube by holding the terminal section of cathode between a planar board and sideboard frame member while holding anode leads between the sideboard frame member and anode substrate and fixing with glass sealing member thereby preventing production of decomposition gas when sealing while preventing air leakage. CONSTITUTION:Anode lead 2a for 7 segment display and wiring conductor 2b are connected to external terminal section 2d of anode substrate 1. Crystal glass sealing member R is applied on the sideboard frame member 6 and planar board 4 then an electrode frame 7 is held between them and burnt under atmosphere to produce crystalized glass. Then the anode substrate 1 and the sideboard frame member 6 integral with the planar board 4 while incorporating with cathode 8 are thermally sealed in vacuum while pressurizing from above and below to construct an outer casing thus to complete a fluorescent character display tube having no exhaust tube observable from the planar board side 4. Since it is burnt in vacuum after evacuating decomposition gas completely, gas is never produced after sealing while since the wiring lead 2b is formed with thin film, contact-tight performance is improved to leak no air.

Title: Image recording head and imaging apparatus
Inventor: YAMAMOTO RYOICHI
IPC: B41J2/205
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality image stably while increasing ink ejection by keeping ink ejection through single displacement of a movable member at a substantially constant level. SOLUTION: When a drive section is driven, a diaphragm 52 advances into a cavity 48 or retracts therefrom to vary the volume of the cavity 48. Consequently, ink flows toward an ink outlet. Since moving range of the diaphragm 52 is regulated, the quantity of ink being ejected through single reciprocation of the diaphragm 52 is constant. Consequently, first and second ink supplies can be regulated with high accuracy by regulating the number of drive pulses being applied to each drive section. According to the arrangement, image quality can be enhanced while stabilizing the operation and the control width of ink ejection can be widened while increasing ink ejection.

Title: Semiconductor integrated circuit
Inventor: IMAMURA KAZUO
IPC: H03K17/567
Filed: 1987-09-04
Abstract: PURPOSE:To speed up operation of the saturation prevention circuit of a bipolar transistor(TR) to be driven by a CMOS circuit by inserting a P channel MOS TR between the power source terminal of a CMOS TR circuit part and the power source terminal of a semiconductor integrated circuit, when the bipolar TR to be driven is an npn TR. CONSTITUTION:The CMOS TR circuit part is constituted of the P channel MOS TR 5 and an N channel MOS TR 6, and the output 7 of said CMOS TR circuit part and the base of the npn TR 10 are connected. Then, by adjusting the threshold voltage of the P channel TR 3 previously at the time of manufacturing, a base current is made to flow into the base of the npn TR 10 within a range that it does not come to a saturated state, extending over the whole range of the change of the base voltage of the npn TR 10. Thus, since the base current flows into the base of the npn TR 10 is limited, the change of the base voltage of the npn TR 10 is stopped before the npn TR 10 is saturated. Thus, the bipolar TR to be driven can be made to operate in a non-saturated state, and therefore, it can be made to operate at high speed.

Title: Imagae forming method
Inventor: SHIGETA KUNIO
IPC: G03G5/06
Filed: 1987-09-04
Abstract: PURPOSE:To obtain an image having a high quality by using a photosensitive body containing a carrier transport substance in a specific carrier generating layer, forming an electrostatic latent image on this photosensitive body, and subsequently, bringing the electrostatic latent image to non-contact development under the alternating electric field. CONSTITUTION:As for a photosensitive body, a photosensitive body whose content ratio to a binder substance of a carrier generating substance 10 is <=1/2, in which the film thickness of a carrier generating layer 2 is >=1mum, and also, in which a carrier transport substance is also contained in the carrier generating layer 2 is used. In this state, an electrostatic latent image is formed on this photosensitive body, and subsequently, the electrostatic latent image is brought to non-contact development under the alternating electric field. In such a way, a dissipation and a decrease of a surface charge caused by a local carrier injection from a conductive base body 1 side can be obstructed, and even in case when an inversion development has been executed, no black potting is generated on the image, and an image being free from an image defect and having a high quality can be obtained.

Title: Box-shaped container
Inventor: KASAHARA TOSHIHIRO
IPC: B65D21/04
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To stack a container in such a manner that the support legs of the upper container is not hindered by the protrusive lines forming the recessed groove of the lower container, by forming the recessed groove only in the flange between pockets and the support legs of respective side walls. SOLUTION: When the upper container Bu is stacked on the lower container Bb while it is slid along the flange 3 of the lower container Bb, it is slid along the flange 3 of the longitudinal side walls 2a, 2b of the container Bb in the state the shorter side walls 2d of one container Bu are lifted. Since the protruded part 6e of the support legs 6 of the container Bu is inserted in the grooves 9a', 9b' of the container Bb, the container Bu is prevented from transferring sideways and hence, the container Bu is prevented from getting out of the container Bb. And hence, the container Bu can be securely stacked. The protruded line 9c is projected only between the wider support legs and the pockets C, in the shorter wall 2c side flange 3 of the container Bb and it is not projected at any other positions. And hence stacking troubles do never arise.

Title: Memory device changing boosting ratio
Inventor: KUROSAKI KAZUHIDE
IPC: G11C16/06
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To ensure a read operation by maintaining a boost voltage for driving a work line in a proper range even to a wider source voltage or a lower source voltage. SOLUTION: In the memory device having a floating gate type memory cell array transistor, a boosting ratio of a boost voltage-generating circuit is set to be variable so that a value of a boost voltage for driving a word line at the read time is constant in accordance with a level of a source voltage. In other words, the boosting ratio is raised when the source voltage steps down, and it is lowered when the source voltage steps up. The boost voltage VPW for driving the word line at the read time can be maintained in a predetermined range, thereby ensuring a normal read operation. More specifically the boosting ratio of the boost voltage circuit is controlled so that a current of a read reference transistor to which the boost voltage VPW is applied is maintained higher than a leak current on a bit line from a permitted memory cell transistor.
