Title: Suspension device for vehicle
Inventor: MASUHARA KENICHI
IPC: B62K5/02
Filed: 1988-03-11
Abstract: PURPOSE:To improve traveling stability by linking the supporting member of cross-arm support shafts which are linked together via a longitudinally directed longitudinal arm, to a linking member which is linked to a rear wheel pivotally installing means to which a rear wheel is provided. CONSTITUTION:So long as front wheels 3a, 3b or a rear wheel 4 is not floated up from a road surface as in the case when a load is applied to the front portion of a body 1 at the time of braking, etc., when a load is applied to the rear portion of the body 1 due to increase in the weight of riders, or when a load is applied to the whole body 1 due to centrifugal force at the time of turningly traveling, and the like, cross-arm support shafts 32, 42 are held by a cross-arm support shaft supporting member 28 so as to be kept nearly horizontally at all times. Hence, when the body 1 is inclined at the turningly traveling time, even if a vehicle is seen in a plan view, the horizontal longitudinal axis in the longitudinal direction of a vehicle is in parallel or in a straight line with the cross-arm support shafts 32, 42. Thereby, both right and left ends of upper and lower arms 31, 41 will not be shifted separately in the unintended longitudinal direction while also preventing an inadvertent steering angle, obtaining a smooth driving feeling while improving traveling stability.

Title: Semiconductor integrated circuit
Inventor: KOMATSU YUUJI
IPC: H01L27/04
Filed: 1983-04-04
Abstract: PURPOSE:To increase the capacitance per unit area by a method wherein a P type region of a high impurity concentration is formed in an Si substrate, which region is made as one electrode of a capacitor, an oxide film and an Si nitride film are formed on the surface thereof, and an electrode is formed thereon in layer form and then made as the other electrode.

Title: Ram control circuit
Inventor: KAWAMURA YASUAKI
IPC: G11C11/419
Filed: 1982-04-09
Abstract: PURPOSE:To obtain an RAM control circuit which outputs a different number of bits stably by controlling an output selecting means selectively by a control signal, and placing a data output line which is not used when data is read out in an insignificant state. CONSTITUTION:When Y1=''0'' and Y1'=''0'', transistors TR1-TR8 all turn off, so data output lines out1-out8 are selected to read 8-bit data OUT1-OUT8. When Y1=''0'' and Y1'=''1'', the TR1-TR4 turn off and the TR5-TR8 turn on, so the data output lines out5-out8 are grounded to be placed in insignificant state. Therefore, the read data OUT1-OUT4 are selected and the OUT5-OUT8 are unselected to read 4-bit data among the data OUT1-OUT4. Consequently, 4-bit data are written in and read out of an RAM having the data output lines for eight bits.

Title: Tough steel with low hardenability
Inventor: NITSUTA KAZUYUKI
IPC: C22C38/00
Filed: 1981-04-21
Abstract: PURPOSE: To inexpensively obtain a track bush, etc. with high wear resistance, bending fatigure strength and impact toughness by reducing the amount of C in a steel to lower the hardenability and by specifying Si, Mn and Al.  
     CONSTITUTION: This tough steel with low hardenability consists of 0.40W0.55% C, 0.05W0.20% Si, 0.20W0.40% Mn, 0.015W0.08% Al and the balance Fe with impurities. This steel is formed into a track bush shown by the figure, and by subjecting the surface parts to high pressure spray hardening and tempering, a product having a high hardness martensite structure at the surface parts and a tough bainite structure at the core part is easily obtd. In said composition the lower limit or more of C is required to maintain the surface hardness and strength, yet more than the upper limit of C hardens the core part as well as the surface parts and deteriorates the toughness. Since Si and Mn increase the hardenability, the upper limits are decided, and the lower limits are minimum amounts necessary for deoxidation and desulfurization. The lower limit or more of Al is required to carry out deoxidation in combination with Si and Mn, yet since excess Al increases the amount of inclusions, the upper limit or less of Al is added.

Title: Heater unit for warm air type electric japanese foot warmer
Inventor: MORIMOTO TETSUJI

Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To uniformly heat the inside of a Japanese foot warmer and to suppress an abnormal temperature increase by controlling the energization of a fan motor according to the detection temperature of a temperature sensor when heating the inside of the Japanese foot warmer by discharging the radiation heat and the conduction heat of a heater forcibly using the fan motor toward the outside a heater unit for heating. SOLUTION: When a heating switch 15 is turned on and a set temperature is set to, for example 'low' when using a Japanese foot warmer, no output is available from a comparator 20 initially since temperature in a heater unit 1 is low, a relay contact 24 is turned off, and the energization of a fan motor 3 is interrupted. On the other hand, a thermostat 6 is ON from the beginning, so that heaters 4, 4 are energized for heating and the temperature in the Japanese foot warmer is rapidly increased. When a detection temperature by a thermistor 5 reaches a specific temperature that is lower than the set temperature, a relay contact 24 is turned on by the output of the comparator 20 and the fan motor 3 is rotated, thus discharging warm air.

Abstract: PURPOSE:To share a call to a proper transfer destination by providing a transfer incoming call controller transferring a call to an extension terminal equipment relating to an incoming call based on identification information of a transfer destination line detected by a transfer destination detector and allowing the system to decide the transfer destination line for each extension terminal equipment being a called destination. CONSTITUTION:A transfer incoming call controller 4 transfers a call to any of extension terminal equipments 11-1n or a line 7 leading to a transfer destination different from a line 2 connecting to a caller based on given identification information of a line of a transmission destination. Moreover, identification information of the line of the transfer destination is given from a transfer destination detector 5 to a message transmission device 8. The device 8 generates a voice message representing it that a call is transferred to the transfer destination based on the identification information of a line of a given transfer destination and sends a voice message to the caller via the line 2 leading to the caller. Thus, when the incoming call is transferred, the transfer to a line with a prescribed relation decided by the called destination and the caller is ensured and the message representing the fact of transfer is sent to the caller, then the service to the caller is enhanced.
