Title: Photoelectric type object detector
Inventor: ISHII TAKESHI
IPC: G01V8/12
Filed: 1989-04-25
Abstract: PURPOSE:To identify the presence or absence of the intrusion of an object by detecting the intensity of the reflected light from a monitoring section intermittently at prescribed sampling intervals and successively and relatively comparing the data on the intensities of a pair of the reflected light rays. CONSTITUTION:A photodetector 7 successively detects the modulating intermittent reflected light rays reflected from a background surface or object surface and intermittently outputs the modulating detection currents having the amplitudes corresponding to the light intensities thereof. An amplifier section 10 detects and amplifies the modulating detection currents and outputs an AD detection signal AC. A smoothing section rectifies and smoothes this signal and outputs a DC detection signal DC. A converting section 12 converts the crest components of the signal DC successively to the corresponding sampling data DATA in synchronization with the sampling signal CTL outputted by a control arithmetic section 14. A memory section 13 alternately records the data DATA and updates the recording data at every inputting. The arithmetic section 14 reads out the updated data DATA recorded in a pair of memory regions M 1, M 2 and computes the relative ratio. The signal indicating the intrusion of the object is outputted when the relative ratio exceeds the set threshold.

Title: Nonvolatile semiconductor memory
Inventor: NODA MASANORI
IPC: H01L21/8246
Filed: 1990-04-20
Abstract: PURPOSE:To improve write characteristics and punch-through voltage while preventing the decrease in breakdown voltage by isolating a semiconductor region from the heavily doped area of a drain region. CONSTITUTION:An impurity introduced is diffused and electrically activated by annealing. As a result, lightly doped areas 6a, 6b, 7a, and 7b are formed under a side wall spacer 4, and a p-type semiconductor region 8 is formed between the lightly doped areas 6b and 7b and a p-type silicon substrate. The p-type semiconductor region 8, between the lightly doped areas 7b in a drain region and the p-type silicon substrate, is not directly in contract with the heavily doped areas in the drain region. If the impurity concentration in the p-type semiconductor region is increased, therefore, it is possible to prevent the decrease in the breakdown voltage between the semiconductor region 8 and the heavily doped areas in drain region 7.

Abstract: PROBLEM TO BE SOLVED: To make the apparent arc length constant by setting the period of counting the number of times of short circuits and the target number of times of the short circuit, starting welding and controlling the output voltage value so that the detected number of times of the short circuits becomes the target number of times of the short circuits. SOLUTION: In order to obtain the suitable apparent arc length La, the suitable ranges of the target number Nr of times of the short circuits and the period Tr of counting the number of times of the short circuits, are set. In a small current zone, a middle current zone and a large current zone, the count periods Tr are set to the same of 1 sec and also, the output voltage value Vt is controlled so as to become the target number Nr of times of the short circuits corresponding to the average value Ia of welding current or the pulse frequency (f) defining this average value.  In the small current zone which sets the frequency to low, the Nr is set to e.g. 4 times, and at the time of controlling the Vt so that the number of the short circuit becomes 4 times, the number of times of the short circuits and the number of times of peak current synchronously become the same of 4 times and the La becomes the suitable value. In the same way, the Nr is set to 6 times in the middle current zone, and 8 times in the large current zone, and then, the suitable La can be obtd.

Abstract: PURPOSE:To shorten the time for curing without shortening the pot life and without adversely affecting a surface smoothing treatment by using the block isocyanate expressed by formula as the binder of magnetic powder. CONSTITUTION:The block agent B of the block isocyanate expressed by the formula I is selected from alcohols, phenols, epsilon-caprolactams, oximes, and active methylene compds.

The dissociation catalyst is a tin compd., etc. The total content of the polyisocyanate and the block isocyanate is selected at 5 to 100pts.wt. per 100pts.wt. total content of the resin component having a hydroxyl group. The isocyanate reproduced by dissociating the block agent reacts only when the magnetic recording medium is heated at the time of production of the medium according to the material of this constitution. The pot life is thus long and only the curing time is shortened. In addition, the durability of the magnetic recording medium itself is improved.

Title: Multi-frequency discriminator circuit
Inventor: JINNO TAKAYUKI
IPC: H04L27/26
Filed: 1978-08-29
Abstract: PURPOSE:To decrease the necessary number of the BPF and the signal detector by installing the BPF which makes pass through the tone signals of different frequencies plus the FM demodulator circuit which detects one wave for the signals passed through the BPF. CONSTITUTION:The grouping is given with every three waves to n units of tone signals in the order of the lower frequencies, and the multi-frequency combination signals selected by such combination method in which just one wave is used in the same group. Such combination signals undergo the amplification and shaping through signal amplifier 2 and are then supplied to signal detector 7 via BPF6 which gives the selective passing to the groups. Detector 7 gives a detective decision which tone signal is received within the same group among the upper, medium and lower rank frequency to obtain each corresponding tone signal detection output 5. In such way, the necessary number can be decreased down to 1/3 from the conventional number for both the BPF and the signal detector, thus securing a wider range for the BPF. As a result, the constitution can be simplified with the increased response velocity.

Filed: 1993-04-09
Abstract: PURPOSE:To facilitate the desired layer design and to improve the characteristics obtainable therefrom by controlling a change in the content of carbon atoms with the content of silicon atoms and a change in the content of boron atoms. CONSTITUTION:A photoconductive layer formed of a non-single crystalline material basically consisting of the silicon atoms and a surface layer are successively laminated on a conductive base body.
