Title: Adduct of omega-guanidino-fatty acid amide and glyoxylic acid, and its preparation
Inventor: UMEDA YOSHIHISA
IPC: C07C239/00
Filed: 1984-02-27
Abstract: NEW MATERIAL:The compound of formula I (n is 6-8; R<1> is H, lower alkyl or benzyl), and its salt. EXAMPLE:(+ or -)-N-(7-Guanidinoheptanoyl)-alpha-hydroxyglycine. USE:A synthetic intermediate of carcinostatic agent. PREPARATION:The objective compound of e.g. formula IV can be prepared by the dehydrative condensation of the omega-guanidinofatty acid amide of formula IIwith glycoxylic acid of formula III. The compound of formula IV can be converted to the chemically stable compound of formula V by the O-alkylation of the 2-hydroxyl group. When a spergualin-relating compound is synthesized via the compound of formula V, it is not necessary to protect and deprotect the highly reactive aldehyde group of the glyoxylic acid, and the group can be converted rapidly to a functional group having high chemical stability and poor reactivity. An optically active compound which has been difficult to resolve optically, can be synthesized relatively easily by this method.

Title: Method for measuring reflection attenuation amount of light connector
Inventor: FUJITA KIYOHISA
IPC: G01M11/02
Filed: 1995-01-31
Abstract: PURPOSE: To improve the productivity by subtracting a value when a value when a difference of measuring values adjacent to a converging value of the reflection attenuation amount of a pair of light connectors converges is supposed to be reduced up to a preliminarily obtained converging time, and estimating a converging value before an actual measuring value converges. CONSTITUTION: The reflection attenuation amount of a light connector is measured by a measuring system. When the measuring result shows a characteristic that the reflection attenuation amount is the maximum value of Y0 at a time T0 , decreases every ΔT time and finally converges at the minimum value, a difference of measuring values adjacent to each other is obtained for every ΔT time. Then, a time N for difference of measuring values to converge is subtracted from a time T1 when the preliminarily obtained reflection attenuation amount of the light connector converges. The subtracting result is divided by the time ΔT thereby to obtain a plot count of the time.  The plot count is multiplied by a converging value YS of the differences of measuring values, which is subtracted from a value of the reflection attenuation amount in the time N when the differences of measuring values are converged to be converging value YS. An estimated value approximate to the converging value is thus obtained.

Title: Digital oscilloscope
Inventor: SATO HIROSHI
IPC: G01R13/22
Filed: 1998-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain a digital oscilloscope in which a start/stop operation can be performed easily by a simple method even when a probe is operated by both hands by a method wherein one end of an OR means receives the ON signal of an external switch, the other end receives the ON signal of a start/stop key which is installed at a main body and an ORed ON signal is output. SOLUTION: An external switch 82 and an OR gate 83 are added. For example, a foot switch is used as the external switch 82. The ON signal of a switch 81 as a start/stop key and the ON signal of the external switch 82 are received by one end and the other end of the OR gate 83, and an OR output is given to a memory control circuit 80. Consequently, in a stop state, the switch 81 or the external switch 82 is pressed once, and a fetch operation is started. In a start state, the switch 81 or the external switch 82 is pressed once again, and the fetch operation is stopped. For example, even when both hands are occupied by probes 11, 12, a foot switch as a start/stop key is pressed by a foot so as to be operated.

Title: Signal selector
Inventor: HOSHINO TAKEHIKO
IPC: H03H17/02
Filed: 1984-02-25
Abstract: PURPOSE:To detect simply and assuredly a fault of the filter characteristics of a signal selecting circuit which is caused by the frequency change of a clock signal or a sampling signal, by supplying the check signal of a fixed frequency produced by a system different from that for the clock signal for signal selecting circuit to a sampling circuit together with the signal to be selected and then monitoring the output level of the check signal which is outputted from the signal selecting circuit. CONSTITUTION:The selection outputs corresponding to input signals are obtained from signal selecting parts 51-5n in accordance with the frequency and the level of the input signal supplied to a terminal 1 as long as each circuit is nondefective. When the frequency of a clock signal CP or a sampling signal SP has a change, it is impossible for a signal selector to select accurately the input signal to the terminal 1 owing to variation of the filter characteristics of a signal selecting circuit 5. Thus the output level of a check signal selecting part 5x is reduced. Then a level monitor circuit 9 detects a fault of said filter characteristics.

Title: D/a converter
Inventor: TSUZUKI HIROYOSHI
IPC: H03M1/76
Filed: 1988-02-19
Abstract: PURPOSE:To decrease the difference between the maximum resistance and the minimum resistance by giving plural partial voltages of reference voltage to the gate of a field effect transistor(FET), controlling the level of a drain terminal to a power source voltage or a ground potential in response to each input bit to switch the FET and adding and outputting source currents. CONSTITUTION:Switches S1-S4 are controlled by using a digital data given to input terminals B1-B4 to control FETst1-t4 to be conductive or nonconductive. Thus, the current sum of a constant current flowing through the FET subjected to conduction control among the FETst1-t4 flows to the fly-back resistor R6 of an operational amplifier Q composing an adder to obtain the output voltage of V6, and since the resistance of adjacent components of a resistance plex connected to the gate circuit of the FETs has only to be varied by the multiple of 2<0.5>, the difference of resistance between the most significant bit and the least significant bit is suppressed to be small.

Abstract: PURPOSE:To uniformly electrify a photosensitive drum by coating a roll electrifier with a semiconductive layer having a semiconductive resistance value to supply a sufficient electrifying current to an indefectible part of the photosensitive drum but to limit an excessive current to a defective part. CONSTITUTION:A soft elastic body layer 3 consisting of rubber or a synthetic resin is joined to the column curved surface of a metallic roll core body 2, and the outside surface of the elastic body layer 3 and both ends of the core body 2 are brought into contact with each other by a thin film conductive layer 4. A semiconductive layer 5 consisting of a natural rubber latex is joined to the curved surface of the outside surface of the conductive layer 4. A roll electrifier 1 is pressed to a photosensitive drum and a supply voltage is applied to the electrifier 1. When the photosensitive drum is electrified, the electrifier 1 supplies a sufficient electrifying current to an indefectible part of the photosensitive drum and limits an excessive current due to discharge to a defective part by the semiconductive resistance value of the semiconductive layer 5. Thus, overheating of the defective part due to discharge heat is prevented. The roll resistance of the core body 2 is made uniform and elasticity is given to it and the electrifier is pressed to uniformly electrify the photosensitive drum.

Abstract: PURPOSE:To prevent unstable images in the area where the small screen used to be by providing a small screen switch to disconnect the small screen image signal processing circuit from the synthesizing circuit in response to the small screen selection signal to vanish the small screen on the CRT. CONSTITUTION:After the completion of playing a video tape, for example, no image signals for the small screen is given, and therefore no flower image as illustrated appears in the small screen for a certain period of time. A specified delay time after small screen image signals to the small screen image signal processing circuit 8 stops, a detection signal is given from the signal detection circuit 12 to the control section 5. This signal turns off the switch 11 so that no small screen image signal is given from the small screen image signal processing circuit 8 to the synthesizing circuit 9, to which main screen image signals alone are given from the main screen image signal processing circuit 7. Thus, image of the flower in the small screen 10b disappears and the main screen occupies the full CRT.
