Title: Electronic balance
Inventor: SATO TAKESHI
IPC: G01G21/30
Filed: 1992-02-26
Abstract: PURPOSE:To detect the tare in compliance with one's aim by so arranging a balance as to generate a first alarm when an instruction to detect the tare is fed while the door of a weighing chamber is opened, and to generate a second alarm after detecting the tare when an instruction to obtain the tare is given again subsequently. CONSTITUTION:When a tare key 10 is depressed, the opening/closing state of a door 4 is recognized from the output of a sensor 5. If the door is kept closed, the weight W on a saucer 2 at this time is stored as a tare T in a tare memory. On the other hand, in the case where the door 4 is opened when the tare key 10 is depressed, the tare is not stored and an alarming lamp 11 is blinked, with a first alarm being generated. When the tare key 10 is pressed again while the first alarming state is continued, if the door 4 is closed then, the alarming lamp 11 is turned OFF and the tare is stored. If the door 4 is still opened when the key 10 is pressed again, the alarming lamp 11 is turned ON and the tare is stored while a second alarm is generated.

Title: Manufacture of low density fuel pellet containing gadolinium oxide
Inventor: YUDA RYOICHI
IPC: G21C3/62
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a fuel pellet having a stable structure with a limited sintering- shrinkage, by press-molding a powder mixture of a uranium dioxide and a gadolinium oxide and then sintering it within a specific temperature range in an oxidizing atmosphere. CONSTITUTION:A powder mixture of a uranium dioxide and a gadolinium oxide is press-molded to produce green pellets and after a preliminary sintering, the pellets are sintered for more than 1hr within a temperature range between 1,400-1,800 deg.C and in an oxidizing atmosphere. As an oxidizing atmosphere, flowing gas consisting of mixture of a hydrogen and a carbondioxide (mixing rate: CO2/H2=0.4-8), or an oxygen and an algon, or an oxygen and a nitrogen (an oxygen concentration for both cases: 5-100ppm) is preferable. In this sintering process, sintering is accelerated at a part which is enough far from the Gd2O3 particle in the pellet and at the part where a ratio of oxygen atoms to metal atoms (O/M) is rather high, while sintering is not much accelerated at a part where the O/M is low and being close to the Gd2O3 particle. Consequently, gas holes at the part where sintering rate is low, are not removed thus low density pellets having comparatively large gas holes can be manufactured.

IPC: H04L25/49
Filed: 1987-02-23
Abstract: PURPOSE:To suppress low frequency components of information signals without increasing the information volume to transmit signals by transposing plural kinds of sampling information signals in accordance with sampling positions to encode them. CONSTITUTION:A picture signal quantized to eight bits is converted to an 8-bit substitutive word having a CDS value corresponding to the quantization level by an encoder 3. Substitutive words having the same CDS value are assigned to input quantization level values of adjacent values fundamentally; but if substitutive words having the same CDS value are not assigned to input quantization level values of adjacent values, substitutive words between which the difference of CDS value is small as much as possible are assigned to them.

IPC: H04N5/16
Filed: 1987-02-24
Abstract: PURPOSE:To decrease the deterioration of a waveform and the potential fluctuation of an output signal in a transient state by limiting the potential fluctuation in a clamping means by providing a potential limiting means to a required minimum value with respect to an output dynamic range. CONSTITUTION:A potential limiting means 22 consists of a transistor (TR) 10 and a constant voltage source 11 so as to limit the transient potential raising in the input signal to a prescribed voltage. That is, when the base potential of the TR 4 is going to be lower than a prescribed voltage V1', a charging current flows from the emitter of the TR 3 of the clamping means 21 to the capacitor 2 rapidly and the base voltage of the TR 4 is kept to V1'. When the base potential of the TR 4 is going to be higher than the potential V3' decided by the TR 10 and the constant current source 11 forming the means 22, the discharge current from the capacitor 2 flows quickly to the emitter of the TR 10 and the voltage does not reach higher than the V3'. Thus, the low potential side among the input signal is matched to the voltage V1', the transient raising of the potential is limited to the voltage V1' and the potential fluctuation of the output signal and waveform deterioration are reduced.
