Title: Disc molding die and molding method therefor
Inventor: ASAI IKUO
IPC: B29L11/00
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To prevent gas in the space within a stamper outer periphery holding- down ring from staying. SOLUTION: A movable side second air path 42 is connected through a change-over valve 50 and pressure regulating valves 51 and 52 to an air supply source 53. Into the space 25a within a stamper outer periphery holding-down ring, low pressure air from the air supply source 53 is blasted at all times through the pressure regulating valve 52 and the change-over valve 50 from the movable side second air path 42. The gas developing at the injection and charging of molding material in a cavity 3 flows not in the space 25a within the stamper outer periphery holding-down ring but from a gap 26a through a gap 26b outside a mold through a path. At the separation of a molded disc from a stamper 7, the change-over valve 50 is changed-over so as to blast high pressure air through the pressure regulating valve 51 into the space 25a.

Title: Magnetic encoder
Inventor: OKAMOTO ATSUSHI
IPC: G01D5/245
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic encoder in which a very small and constant gap can be ensured easily by a method wherein a magnetoresistive element pattern is vapor-deposited on a flexible printed-circuit board(FPC) and the board is installed so as to match the curvature of a magnetic drum. SOLUTION: A pulse-magnetized magnetic drum 2 is mounted on, and attached to, a shaft 3, and magnetism is detected by a magnetoresistive element 7. A magnetoresistive element pattern 4 is vapor-deposited onto an FPC 5, the FPC 5 is formed an pasted in an arc shape so as to match the curvature of the drum 2, and the pattern 4 is protected by a glass, a resin or the like. Therefore, a very small and constant gap can be ensured easily and surely between the element 7 and the outer circumference of the drum 2. In addition, when the outside diameter of the drum 2 is changed, the curvature of the element 7 can be changed easily so as to match the outside diameter, and no bad influence is exerted on the magnetism-sensing capability of the element 7.

IPC: B60K23/02
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To enable smooth start to be achieved without complicating a program for controlling a clutch engaging pressure by installing an electrically driven pump other than a hydraulic pump directly connected to an engine as a means for supplying hydraulic pressure to a starting clutch. SOLUTION: In such a device as supplying hydraulic pressure fed to a starting clutch 10 from the first hydraulic pump 21 directly connected to an engine, the second hydraulic pump 41 driven by an electric motor 43 is provided outside the system of the first hydraulic pump 21 and further construction is realized in such a manner that the clutch tightening pressure is fed to the starting clutch 10 from this pump 41 via piping 32 and a solenoid valve 23. In this case, a proportional valve is used for the solenoid valve 23 and by precisely controlling the hydraulic pressure by means of a control system, an automobile can make its start smoothly.  In addition, with regard to the hydraulic pressure supplied to the solenoid valve 23, since a constant pressure is supplied from the second hydraulic pump 41, smooth starting characteristic is secured by only controlling the solenoid valve 23 by means of a comparatively simple program.

Title: Burner for analysis
Inventor: SUZUKI KOHEI
IPC: F23D11/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of concentration measurement in sample gas, to extend a measuring range, to ensure stability of light emitting intensity and to prevent condensation of alkali metal component by providing a sample gas tube for injecting the gas, and a sample gas temperature regulator disposed around the tube. SOLUTION: An emitting intensity of an atom emission spectral ray generated from atom of ignited alkali metal is measured by a detector 6.

Since a sample gas tube 2 is heated by a sample gas temperature regulator 5A and the air and combustion gas are heated by an air temperature regulator 5B and a combustion gas temperature regulator 5C on the way up to its injection, saturated vapor pressure of the metal in the gas is not lowered, and hence condensation of the metal can be prevented. Here, when hydrogen gas is used as the combustion gas, burner flame becomes colorless, and accuracy of measurement is improved.

IPC: A61B5/00
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To objectively and exactly evaluate stiff shoulders by tracing the activity of the autonomic nerves and determining the stiff shoulders when the sympathetic nerves are in active state. SOLUTION: An electrocardiograph 16 as a measuring device for measuring parameters necessary for analyzing the activity of the autonomic nerves, and data obtained by measuring heart beats are input to a CPU 14 via an input device 11. Those input data are frequency analyzed, and the value of HF/(LF+ HF) is computed from power values (HF and LF values) in prescribed high and low frequency bands. These actual and standard values are compared to determine whether the measurement showing the activity of the sympathetic nerves is higher than the standard value and the measurement showing the activity of the parasympathetic nerves is lower than the standard value. If the result of determination is 'YES', the condition is determined as being stiff shoulders, and the result is output on an output device 13 and displayed on a display device.
