Title: Molding of aromatic polysulfone resin
Inventor: GOTOU YOSHIHISA
IPC: C08K5/09
Filed: 1984-01-17
Abstract: PURPOSE:To produce a high-quality molding in good releasability by using a small amount of a releasing agent, by applying a finely powdered releasing agent to the surface of an aromatic polysulfone resin and molding this resin. CONSTITUTION:The surfaces of pellets or powder of an aromatic polysulfone resin are coated with about 200-1,000ppm of a powdered releasing agent, and this resin is molded. As the above releasing agent, a metallic soap releasing agent (e.g., 10-30C fatty acid magnesium salt) and/or a fatty acid amide releasing agent (e.g., 10-30C fatty acid amide) are used. According to the above process, it is possible to produce a molding of excellent quality in good releasability without detriment to mechanical strength, thermal performances, appearance, etc., by using even an extremely small amount of a releasing agent, unlike a conventional process wherein an aromatic polysulfone resin containing a releasing agent is molded.

Title: Solid-state imaging element and its manufacturing method
Inventor: ASAI ATSUSHI
IPC: H01L21/265
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To handle larger signal electric charge amount for wider dynamic range, by providing an impurity diffusion region of wider width than formed by single-direction ion implantation. SOLUTION: With the process of ion-implantation that of inclined in a vertical transfer forward direction and that of ion-implantation inclined in the direction opposite to the vertical transfer direction, a width W1 of an impurity diffusion region 13 is formed larger than that with ion-implantation in normal vertical direction. An electric charge accumulation amount is decided by distribution of impurity element forming a sensor part in a semiconductor substrate 11. Thus, by forming the width W1 of the impurity diffusion region 13 larger, in short, wider than the sensor part, the amount of electric charge accumulation of the entire sensor part is larger. Thus, the dynamic range of a CCD solid-state imaging element is larger.

Title: Integral interpolating device for pcm modulator/ demodulator
Inventor: YONETANI JUNICHI
IPC: H03M1/66
Filed: 1990-01-11
Abstract: PURPOSE:To modulate/demodulate a faithful original waveform without increasing a sampling frequency by adding an integrated value at every one-sampling period of the difference signal between a signal before modulation and a delay signal to a delay signal. CONSTITUTION:Quantized data after PCM modulation is converted by an amplitude discrete/continuous converter 1 into a rectangular wave signal having an amplitude corresponding to each quantized data. Its output A is delayed by the delay circuit 2 by one sampling period and outputted as a signal B. The signals A and B are inputted to a subtracter 3 to generate the difference signal C(=A-B). The signal C is integrated by a reset integration circuit 4 at every sampling period. The output of the circuit 4 and the output signal B are added by an adder 5 to generate a continuous signal E. The signal E is a signal generated by linear interpolation between sample points in a discrete state and contains no sampling frequency component, so a side band due to the sampling frequency and the modulation of the original signal is not generated.

Title: Control method of internal combustion engine
Inventor: SHIMIZU KIYOSHI
IPC: F02D41/14
Filed: 1993-01-19
Abstract: PURPOSE:To control a span of ignition timing in an internal combustion engine for its feedback so as to accord a combustion roughness value with the target roughness value on the basis of the combustion roughness value sought by means of an ionization current process. CONSTITUTION:When a combustion roughness value RN is smaller than the target roughness value RNref at a step S58, a constant A (>1) is multiplied to a roughness correction factor KRN at a step S59, while the combustion roughness value RN becomes more than the target roughness value RNref, a constant B (<1) is multiplied to the roughness correction factor KRN at a step S60, and an ignition timing command value thetaIG is compensated by the roughness correction factor KRN at a step S61 in succession. Since both these constant A and B have a relationship of ¦A-1¦<¦1B¦, in the case where the combustion roughness value RN goes beyond the target roughness value RNref and its burningness is worsened, the ignition timing command value thetaIG is suddenly reduced and thereby the combustion roughness value RN can be quickly accorded with the target roughness value RNref.
