Title: Apparatus and method for shortening test time in dynamic random access memory
Inventor: HASHIMOTO SEIJI
IPC: G11C11/409
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To shorten the time for testing parameter of data hold time of a storage cell in a dynamic random access memory without complicating the constitution. SOLUTION: In comparing with a voltage impressed during the operation of a memory cell, the level of a voltage impressed to elements 13, 14 constituting a storage cell (or a plurality of voltage levels) is changed, so that a voltage difference at bit lines 1, 2 detected by a sense amplifier 9 is reduced. Accordingly, a data hold time is reduced because of a reduction of charges in the storage cell. The changed voltage (or a plurality of changed voltages) is impressed to storage cell bit lines 1, 2 and/or a storage cell dummy capacitor.

Title: Electrophotographic recorder
Inventor: KATO KOJI
IPC: G03G15/01
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain high transfer efficiency and high image quality in toners having different polarities, that is, negative and positive polarities, in aligning the polarities of both of the toners on a photoreceptor. SOLUTION: Three stage levels of high, middle, low potential parts (VH, VM and VL) are set with a laser exposure on the photoreceptor 1. In the high potential part (VH), normal development with the toner having the polarity opposite to that of the photoreceptor is attained and in the low potential part (VL), reversal development with the toner having the same polarity as that of the photoreceptor 1 is attained. Then, an electric charge having the polarity different from that of the photoreceptor 1 is applied by the pretransfer electrifier 6, to reverse the polarity of the toner after the development in the low potential part (VL). Here, the quantity of the charge applied from the pretransfer electrifier 6 is one for making the potential of the middle potential part (VM) almost the same as that of the low potential part (VL).

Title: Protective resistor provided with switch
Inventor: NAKAJIMA HIROSHI
IPC: H01F6/02
Filed: 1991-11-08
Abstract: PURPOSE:To ensure reliability of protective system by opening a protective resistor circuit based on an external signal only at the time of magnetizing or demagnetizing a superconducting coil. CONSTITUTION:When a superconducting magnet is magnetized or demagnetized, an electric contact making/breaking medium supply port 9 is previously fed with external medium such as air so that an electric contact making/breaking cylinder 8 is operated to open the electric contact 7 of a switch thus interrupting electric circuit for a protective resistor 4. Consequently, current is not shunt at all to the protective resistor 4 when the superconducting magnet is magnetized or demagnetized. Upon finish of magnetization or demagnetization, air supply to the medium supply port 9 is stopped. Consequently, the cylinder 8 is drained and the electric contact 7 of switch is automatically closed by means of a spring 10 thus establishing the electric circuit for the protective resistor 4. According to the constitution, essential protective function of superconducting magnet is ensured.

Title: Semiconductor non-volatile memory and its writing method
Inventor: IMAI TOSHIO
IPC: G11C17/12
Filed: 1990-11-26
Abstract: PURPOSE:To produce a non-volatile memory which allows writing only once by applying high negative voltage on the source of an n-channel MOS transistor and breaking the junction between a drain and a substrate. CONSTITUTION:Information writing is performed by applying a voltage Vpp, which causes the potential difference Vds (Vdd-Vpp) between a source 112 connected through a bit line 115 and a drain 111 to exceed the drain withstand voltage of a transistor 101, on a terminal 105 and by breaking the junction between the drain 111 and a substrate electrode 114. At that time, since current flows from a diode 103 to the source 112 through resistances 104 and 102, the potential of a gate 113 turns on the transistor 101. As for the information reading, a condition that the potential of the bit line 115 is higher than (Vdd-Vss)/2 is displayed by '1', and the condition lower is displayed by '0'. From the transistor 101, the '1' is outputted since the drain and the source are short- circuited, and from a non-written transistor, the '0' is read.

Title: Convergence type optical transmission device of sunlight lighting system
Inventor: HASHIMOTO SHINICHI
IPC: F21V8/00
Filed: 1990-11-26
Abstract: PURPOSE:To obtain an optical transmission duct of smaller diameter and reduce the cost by transmitting the reflected luminous flux of the sunlight after converged to parallel luminous flux. CONSTITUTION:The reflected luminous flux of the sunlight guided by means of a reflecting mirror 7a of a sun-tracking device 7 is converged by means of a Fresnel lens 9a of a condenser 10 of a convergence type optical transmission device 8 to obtain parallel luminous flux by mans of a collimator lens 9b, and transmitted. Thus, the diameter of a cylindrical optical transmission duct 11 which serves as the transmitting path of the luminous flux can be made smaller since the diameter of the luminous flux to be transmitted is small. Further, the transmittable quantity of light is not restricted by the diameter of the optical transmission duct 11, enabling increase of the lighting quantity while the optical transmission device 8 is kept compact in size. This constitution allows the spacial restriction within the device to be released, enabling the cost reduction.

Title: Communication equipment
Inventor: HORAGUCHI YOICHI
IPC: G06T1/00
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To perform timer transmission at the set time even in a light source requiring the time for reaching required light quantity stably after energizing by controlling a light source driving means prescribed time before the set time of timer transmission start and turning the light source ON. SOLUTION: When an original 20 is set to a read part 11, an original sensor 18 detects the setting of the original 20 and the light source 15 is turned ON. When a user selects a timer transmission mode, the light source 15 is tentatively turned OFF and the light source 15 is turned ON the prescribed time before the transmission set time. Thus, the light source 15 is sufficiently started at the transmission set time and transmission is immediately started. Also, since there is the case that the light source 15 is not sufficiently started at the transmission set time, the prescribed time from the ON of the light source 15 to the timer transmission set time is changed corresponding to the measured result of the start-up time.  In the case that the light quantity of the light source 15 does not reach prescribed light quantity even after the lapse of a sufficiently long time, a fault is judged and end is performed without performing transmission.
