Title: Pulse frequency modulating device
Inventor: TANAKA TSUTOMU
IPC: H03K7/06
Filed: 1984-07-19
Abstract: PURPOSE:To better linearity of modulation in high frequency by making duty nearly 50% in maximum repetitive frequency using a PFM modulator, a delay circuit and a logical sum circuit. CONSTITUTION:Pulse 8 from the PFM modulator A has pulse width (td) determined by a monostable multivibrator 5. The pulse width (td) is smaller than (1/2) fmax and duty is set to lass than 50% even if it is maximum repetitive frequency. The pulse 8 passes through the delay circuit and generates time lag of (tg), and logical sum with original pulse 8 is taken in an OR gate 10. By selecting time lag (tg) to make pulse width (td+tg) of the output (td+tg)approx.=(1/2)fmax, the duty becomes 50% in maximum repetitive frequency. Thus, the linearity of modulation in high frequency can be bettered.

IPC: F01L3/24
Filed: 1986-06-26
Abstract: PURPOSE:To find the width and shape of the valve sheet of an engine not visually with high accuracy without recourse to vision by bringing a detection surface which is divided in a matrix form by optical fiber end surfaces into a close contact with the valve sheet and detecting which optical fiber light is incident on. CONSTITUTION:The detection surface 28 is brought just into contact with the valve sheet 20 and irradiated with light from a light source 30 through a radiation window 23. The projected light is reflected by the periphery of the valve sheet 20, i.e. the internal wall of a cylinder head 10 and incident on the end surface of the optical fiber cable cable 16 of a detection part 28 that the vale sheet 20 does not contact. This incident optical signal is passed through the optical fiber cable 26 and converted by a signal conversion part 34 into an electrical signal, which is supplied to a graphic form recognition and storage part 36. This graphic form recognition and storage part 36 consists of a matrix type storage part corresponding to an optical fiber array on the detection part 28 and its output signal is supplied to an arithmetic part 38 to compute the width and shape of the valve sheet.

Title: Flat package type semiconductor device
Inventor: FUJIZU TAKAO
IPC: H01L23/50
Filed: 1989-06-14
Abstract: PURPOSE:To improve the flatness of a lead top and to improve connection strength at the time of soldering on a printed wiring board, and to enable prevention of connection inferiority by making the lead width smaller than that of the shoulder part over the range of required length from the top. CONSTITUTION:For a lead 13, the lead width of the top part 13b over a required range from the top is narrower than the width of a shoulder part 13a where strength is required to maintain the external lead 13 in a fixed shape. Hereby, within the external lead 13, the elastic deformation area such as spring back, etc., becomes narrow only at the top part 13b, and the rigidity lowers, whereby the flatness improves. The connection strength and the reliability, in the case where a semiconductor devices is mounted on a printed wiring board by soldering, can be improved.

Title: Surface-crosslinked protein prepartion
Inventor: IKADA YOSHITO
IPC: A61K38/00
Filed: 1993-05-27
Abstract: PURPOSE:To provide a surface-crosslinked protein preparation always stably containing a medicinal ingredient and enabling a desired sustained release without deteriorating the original physiological activity of the medicinal ingredient. CONSTITUTION:This preparation is obtained by crosslinking only the surface- near parts of a protein carrier containing a medicinal ingredient, especially a protein medicinal ingredient, with an oleophilic crosslinking agent without affecting the contained medicinal ingredient by the crosslinking reaction, and is stabilized so as to preserve the early physiological activity of the medicinal ingredient as such, achieving a desired sustained release. The surface-crosslinked protein preparation is obtained as follows: adding an aqueous solution comprising the protein carrier and the protein medicinal ingredient to an organic solvent containing a surfactant for stabilizing the emulsion, homogenizing the mixture, pouring the obtained emulsion into a preliminarily cooled organic solvent containing the surfactant to form a protein carrier-containing emulsion, and subsequently adding an oleophilic crosslinking agent (e.g. hexamethylene diisocyanate, oxalyl chloride) to the formed emulsion to crosslink only the surface-near parts of the protein carrier emulsion.

Title: Facsimile equipment
Inventor: OGAWA KIYOSHI
IPC: H04N1/00
Filed: 1990-06-11
Abstract: PURPOSE:To reduce the wait time of the operator and to improve the efficiency of transmission operation by receiving communication to read an original into a picture storage section and using a count means to await the communication start and receiving succeeding communication during that time. CONSTITUTION:When an input original 1 is set to a read section 2, a discrimination means 11 discriminates whether or not the input original satisfies a prescribed communication start wait condition. When the discrimination result by the discrimination means satisfies the condition, communication control information relating to the input original is stored in a storage means 13. Then the communication start control means 11 starts the operation of the count means 14 by the set signal and allows the communication start operation of the communication control section 6 to be awaited when the count operation is within a set time thereby allowing the read section 2 to accept a succeeding input original. Thus, plural communication operations are accepted at once without awaiting the end of preceding communication and the wait time is reduced and the efficiency of the transmission operation is improved.

Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To provide an image reader which can remove the noise component of image data or can simulate an image having noise components in small scale circuit configuration. SOLUTION: Colors at position which are not affected by defects, and colors at positions affected by defects are respectively red tow in twos (S2-S8).

When the image-reneging mode is a mode for generating an image having no defect [(b) in S16], a color D' at a position having a defect is read and a color D in the case of assuming the absence of defect at that position is calculated (S22 and S24) from the color D', the transmissivity of defect and the color of defect.
